Definitions
- the present invention relates to a process for the conversion of a hydrocarbonaceous feedstock and is particularly concerned with the upgrading of certain feedstocks.
- US 4,171,257 describes a process for upgrading a hydrocarbonaceous feedstock by contacting the feedstock with a ZSM-5 crystalline aluminosilicate catalyst at a pressure below 14 bar, a temperature of 260 to 427 °C and a space velocity of 0.1 to 15 l/l.h.
- the feedstock exemplified as gas oil having a boiling point range of 230 to 437 °C, must contain less than 5 ppmw of nitrogen-containing compounds, calculated as nitrogen.
- the upgraded product includes olefinic hydrocarbons, such as propene and butenes.
- US 4,502,945 describes a dewaxing process for upgrading a paraffinic hydrocarbonaceous feedstock by contacting the feedstock with an intermediate pore size zeolite at a pressure of 1 to 8 bar, a temperature of 290 to 595C, preferably of 340 to 480C, and a space velocity of 0.1 to 50 v/v/hr.
- the zeolite must have a silica:alumina mole ratio from about 175:1 to about 300:1 and is preferably ZSM-5.
- the upgraded product includes olefinic hydrocarbons such as propene and butenes.
- US 3,856,659 describes a multistage hydrocarbon conversion operation in the presence of a dual cracking catalyst composition comprising ZSM-5 material, for the production of gasoline and olefinic components, employing one or more riser reactors in parallel flow arrangement wherein the larger and smaller pore catalytic cracking materials comprising the dual function catalyst work substantially independently in their restructuring of hydrocarbon constituents coming in contact therewith under particularly selected operating conditions.
- a first hydrocarbon feed contacts the dual function catalyst in a riser conversion zone
- the dual function Catalyst is then contacted with a second hydrocarbon feed more refractory than the first under conditions to substantially deactivate the cracking activity of the large pore catalyst component without undesirably influencing the activity of the small pore catalyst component which can then be contacted with low boiling hydrocarbon components to effect their restructuring to cyclic components of relatively high octane rating.
- the present invention provides a process for the conversion of a hydrotreated and/or hydrocracked heavy hydrocarbonaceous feedstock to obtain a high proportion of olefinically unsaturated gaseous products, which process comprises contacting the feedstock in a single stage with a zeolitic catalyst comprising a zeolite with a pore diameter of 0.4 to 0.7 nm wherein the contacting is carried out at a catalyst/feedstock weight ratio from 2 to 200, a temperature of greater than or equal to 480 °C and a pressure of up to 10 bar during less than 10 seconds.
- the feedstock is contacted with the zeolitic catalyst for less than 10 seconds.
- the minimum contact time is 0.1 second. Very good results are obtainable with a process in which the feedstock is contacted with the zeolitic catalyst during 1 to 6 seconds.
- the temperature during the reaction is relatively high. However, the combination of high temperature and short residence time allows a high conversion to olefins.
- a preferred temperature range is 480 to 900 °C, more preferably 500 to 750 °C.
- the zeolitic catalyst comprises a zeolite with a pore diameter of from 0.4 to 0.7 nm.
- the catalyst suitably further comprises a refractory oxide that serves as binder material. Suitable refractory oxides include alumina, silica, silica-alumina, magnesia, titania, zirconia and mixtures thereof. Alumina is especially preferred.
- the weight ratio of refractory oxide and zeolite suitably ranges from 10:90 to 90:10, preferably 50:50 to 85:15.
- the catalyst may comprise further zeolites with a pore diameter above 0.7 nm.
- zeolites include the faujasite-type zeolites, zeolite beta, zeolite omega and in particular zeolite X and Y.
- the zeolitic catalyst preferably comprises as zeolite substantially only zeolites with a pore diameter of from 0.4 to 0.7 nm.
- zeolite in this specification is not to be regarded as comprising only crystalline aluminium silicates.
- the term also includes crystalline silica (silicalite), silicoaluminophosphates (SAPO), chromosilicates, gallium silicates, iron silicates, aluminium phosphates (ALPO), titanium aluminosilicates (TASO), boron silicates, titanium aluminophosphates (TAPO) and iron aluminosilicates.
- Examples of zeolites that may be used in the process of the invention and that have a pore diameter of 0.4 to 0.7 nm include SAPO-4 and SAPO-11, which are described in US-A-4,440,871, ALPO-11, described in US-A-4,310,440, TAPO-11, described in US-A-4,500,651, TASO-45, described in EP-A-229,295, boron silicates, described in e.g. US-A-4,254,297, aluminium silicates like erionite, ferrierite, theta and the ZSM-type zeolites such as ZSM-5, ZSM-11, ZSM-12, ZSM-35, ZSM-23, and ZSM-38.
- SAPO-4 and SAPO-11 which are described in US-A-4,440,871, ALPO-11, described in US-A-4,310,440, TAPO-11, described in US-A-4,500,651, TASO-45, described in EP-A-229,29
- the zeolite is selected from the group consisting of crystalline metal silicates having a ZSM-5 structure, ferrierite, erionite and mixtures thereof.
- crystalline metal silicates with ZSM-5 structure are aluminium, gallium, iron, scandium, rhodium and/or scandium silicates as described in e.g. GB-B-2,110,559.
- the zeolites usually a significant amount of alkali metal oxide is present in the prepared zeolite.
- the amount of alkali metal is removed by methods known in the art, such as ion exchange, optionally followed by calcination, to yield the zeolite in its hydrogen form.
- the zeolite used in the present process is substantially in its hydrogen form.
- Olefin production is facilitated by the absence of hydrogen or a hydrogen donor.
- the present process is advantageously carried out in the absence of added hydrogen and/or steam. It is, of course, possible that during the reaction some small molecules, such as hydrogen molecules are formed. However, this amount is usually negligible and will be less than 0.5 %wt of the product.
- the pressure in the present process can be varied within wide ranges. It is, however, preferred that the pressure is such that at the prevailing temperature the feedstock is substantially in its gaseous phase. Then it is easier to achieve the short contact times envisaged. Hence, the pressure is preferably relatively low. This is the more advantageous since no expensive compressors and high-pressure vessels and other equipment are necessary. Pressures up to 10 bar can be employed. Subatmospheric pressures are possible, but not preferred. The minimum pressure is suitably 1 bar. It is economically advantageous to operate at atmospheric pressure.
- the catalyst/feedstock weight ratio may vary widely, for example up to 200 kg of catalyst per kg of feedstock. Preferably, the catalyst/feedstock weight ratio is from 2 to 200.
- the process according to the present invention may be carried out in a fixed bed. However, this would imply that extremely high space velocities be required to attain the short contact times envisaged. Therefore, the present process is preferably carried out in a moving bed.
- the bed of catalyst may move upwards or downwards. When the bed moves upwards a process similar to a fluidized catalytic cracking process is obtained. Preferably, the process is carried out in a downwardly moving bed.
- the catalyst is regenerated by subjecting it, after having been contacted with the feedstock, to a treatment with an oxidizing gas, such as air.
- a continuous regeneration similar to the regeneration carried out in a fluidized catalytic cracking process, is especially preferred.
- the coke formation does not occur at a very high rate.
- the contact time between feedstock and catalyst should be less than 10 seconds.
- the contact time generally corresponds with the residence time of the feedstock.
- the residence time of the catalyst is from 1 to 20 times the residence time of the feedstock.
- the feedstock which is to be converted in the present process comprises hydrotreated and/or hydrocracked hydrocarbons, preferably, though not necessarily, heavy feedstocks.
- Suitable feedstocks are obtained by hydrotreating and/or hydrocracking heavy flashed distillate fractions from long residue or deasphalted oils obtained from short residue.
- the feedstock is suitably fractionated to remove lower boiling fractions after hydrotreating and/or hydrocracking and prior to contacting with the zeolitic catalyst in accordance with the invention.
- the product obtained by the process of the invention is optionally fractionated to yield an olefin-rich gas fraction, a gasoline fraction and a bottom fraction, all or part of which is optionally recycled to the feedstock upstream of the hydrotreating and/or hydrocracking unit. In this way, high conversion of the heavy deasphalted oil or heavy flashed discillate feedstock to more valuable olefin-rich gas is obtained.
- a process for the conversion of a hydrocarbonaceous feedstock comprising hydrotreating and/or hydrocracking said feedstock in the presence of a suitable catalyst, contacting at least a part of the hydrotreated and/or hydrocracked product with a zeolitic catalyst comprising a zeolite with a pore diameter of 0.4 to 0.7 nm at a temperature of greater than 480 °C and a pressure of up to 10 bar during less than 10 seconds, fractionating the resulting converted material and recycling a heavier fraction to said hydrotreating and/or hydrocracking step.
- the said hydrotreating step is known in the art and may be carried out at known conditions. Suitable conditions include a temperature of 150 to 400 °C, a hydrogen (partial) pressure of 30 to 150 bar, a space velocity of 0.5 to 4.0 kg/l.h and a hydrogen/feedstock ratio of 100 to 2000 Nl/kg.
- Suitable hydrotreating catalysts- comprise nickel, cobalt, tungsten, molybdenum, platinum, palladium or mixtures thereof on a carrier, such as alumina, silica-alumina, silica, zirconia, zeolites and the like.
- the catalyst may further comprise fluorine, phosphorus and/or boron.
- the temperature, gas rate and space velocity can be selected by the person skilled in the art, suitably from the range given above.
- Hydrocracking is also known in the art and may be carried out under known conditions, such as over a hydrocracking catalyst at a temperature of 300 to 450 °C, a hydrogen (partial) pressure of 50 to 200 bar, a space velocity of 0.5 to 2.0 kg/l.catalyst.h and a H2/mineral oil fraction ratio of 500 to 2000 Nl/kg.
- the hydrocracking catalyst can be selected from any hydrocracking catalyst known in the art.
- the hydrocracking catalyst comprises a carrier and at least one hydrogenating metal or a compound thereof, which carrier has been selected from the group consisting of silica, alumina, silica-alumina and the faujasite-type zeolites.
- the most preferred faujasite-type zeolite is zeolite Y.
- the most preferred hydrogenating metals are nickel, cobalt, tungsten and molybdenum and mixtures thereof, but platinum and/or palladium may also be used.
- the catalyst may further comprise fluorine and/or phosphorus and/or boron.
- nickel, cobalt, molybdenum and/or tungsten are used as hydrogenating metal, they are preferably present in the form of their sulphides.
- a feedstock with a nitrogen content greater than 5 ppmw may be used with substantially no effect on the catalyst activity.
- Suitable feedstocks may have a nitrogen content of more than 10 ppmw, calculated as nitrogen.
- the feedstock may even have a nitrogen content of 1000 ppmw or more, calculated as nitrogen.
- the feedstock in this example was a hydrotreated Arabian light deasphalted oil having the following properties: IBP, °C 453 50 %wt 591 67 %wt 620 density 70/4 0.8532 kg/l sulphur 232 ppmw nitrogen 12 ppmw
- the DAO feedstock was upgraded in a downflow reactor by passing it downwards co-currently with a flow of catalyst particles.
- the catalyst comprised ZSM-5 in an alumina matrix (weight ratio ZSM-5/alumina 1:3).
- the experiment was carried out at atmospheric pressure. Further process conditions and the results of the experiment are given in Table 1 below.
- the feedstock in this example was a hydrocracked heavy flashed distillate having the following properties: IBP, °C 330 50 %wt 432 FBP, °C 620 fraction boiling below 370 °C, %wt 7.7 density 70/4 0.8157 kg/l sulphur 20 ppmw nitrogen 2 ppmw
- Feedstock was introduced on line 1, after mixing with hydrogen from line 2, to a hydrotreating/hydrocracking unit 3 operated at 90 bar hydrogen partial pressure at 400 °C with a suitable Ni/Mo/alumina hydrotreating cacalyst.
- the hydrotreated product was fractionated in unit 4 into a gaseous fraction 5, a naphtha fraction 6, a kerosine fraction 7, a gas oil fraction 8 and a bottoms fraction 9.
- bottoms fraction 9 was passed to a downflow reactor 10 as described in Example 1, containing catalyst as described in Example 1 and provided with suitable regeneration means from which coke can be removed in line 11 when necessary, while gaseous and liquid product is separated in fractionation unit 12 into a gaseous product 13, a gasoline product 14 and a bottoms stream 15, which is recycled to the feedstock in line 1 for re-processing.
- Bottoms fraction 9 which is upgraded in reactor 10 comprises about 69% by weight based on the initial feed in line 1 when fractionated in unit 12.
