Definitions
- the present invention relates to a new and advantageous catalyst for use during a single-stage Gasoline production process from syngas and a process making use of the same.
- the catalyst can be regenerated in an easy manner without stopping the process.
- Such a process is more economic and still further leads to constant octane numbers of the product at values of about 95.
- the new process prevents the catalyst from deactivation and increases its capacity, resulting in better conversion rates, becoming even better after each regeneration step. Also, with the process according to the invention the catalyst's lifetime is significantly prolonged, making the whole process more economic.
- the Fischer-Tropsch (FT) process was first commercially applied in 1930, in Germany, where, using a cobalt catalyst together with a promoter in a fixed bed reactor, more than 10000 barrels of hydrocarbons were daily produced.
- US 3,958,957 reports about regeneration of a catalyst through oxidation by air.
- US 4,151,190 refers to a method for regenerating a catalyst by hydrogen gas at 500 to 600°C, applying a process that takes 16 hours of time.
- the catalyst used according to US 4,738,948 contains Co and Ru and was regenerated by hydrogen gas at temperatures between 150 to 300 °C.
- US 5,728,918 describes a method for regenerating a cobalt based catalyst comprising a support, which is used to synthesize C 5 + hydrocarbons.
- This method includes the application of carbon monoxide and 30 percent of hydrogen gas at a temperature which is 10°C higher than the one usually used during FT process (that is 220 to 230 °C), under pressure of from 0.5 to 10 bars for 1 to 15 hours.
- the cobalt based catalyst used in the FT process described in the US 4,595,703 was regenerated by making use of hydrogen gas in the presence of nitrogen, carbon monoxide and methane gas at the same temperature as the reaction temperature.
- the regeneration process of a catalyst depends on multiple factors, such as operation conditions of the reactor type, the structure of the catalyst, the type of end products and the reduction and activation conditions for the particular catalyst. As a result, finding a suitable regeneration process differs from case to case, even if with a similar process only operation conditions are changed.
- Regeneration includes the elimination of the sediment coke built on the surface of the catalyst by hydrogenation and/or combustion with oxygen. For such regeneration processes, the whole FT process has to be stopped and then resumed after the regeneration step.
- a catalyst based on iron compounds as catalytically active species comprising further Zeolite components shows superior qualities during FT synthesis processes, in particular as to superior possibilities for its regeneration.
- the whole FT can be run continuously without any interruption for catalyst regeneration.
- the whole process, including the regeneration process of the catalyst can be furthermore improved with adopting particular process parameter, such as the space velocity, which makes an easy regeneration of the catalyst possible while continuously running the process.
- the deactivation of the catalyst is to be regarded in connection with the following parameters:
- sedimentation of carbon compounds on the active sites of the iron - Zeolite catalyst leads to deactivation.
- the decomposition of methane is endothermic while the disproportionation of CO is exothermic. So, by increasing the temperature, the methane decomposition increases, while the disproportionation of CO declines.
- Another aspect when regarding the activity of a catalyst in a FT process is the coverage of the Zeolite components present in the system, as a result of which the active acidic sites are hidden from the reactants and don't take part in the overall reaction.
- the advantageous catalyst and a process for its regeneration lead to significant and up to two times longer life times of the Fe Zeolite catalyst while the whole FT process runs without interruption and with a constant selectivity of the catalyst throughput.
- the Fe catalyst is prepared by the co- precipitation of a solution of respective cations Fe 2+ , Fe 3+ and Cu 2+ with a bicarbonate or sodium carbonate solution.

- Both solutions are heated up to 60 to 80 °C, and are then added to the precipitation system that contains 100 to 1000 millilitres of deionised water, that is heated up to the same temperature used for the ionic solutions.
- the rate of the addition of the solutions to the precipitation system is controlled such that the pH value of the solution remains between 5 to9.
- the precipitates are filtrated off and washed with deionised water for several times to eliminate all the remaining cations and anions.
- the alkaline salt and surface area modifiers potassium silicate together with a silica-sol solution is added to the resulting cake.

- the weight percent of the final Fe- Zeolite catalyst is composed of from 10 to 30 percent of iron and from 70 to 90 percent of the Zeolite.
- an appropriate adhesive agent having a good thermal and mechanical as well as abrasion resistance is formed, which adhesive agent does not have any negative effect on the selectivity of the desired end products and the activity of the catalyst.
- Alumina, silica and silica - alumina gels were used for this purpose, in total weight percents of from 10 to 30.
- the alumina gel was prepared by dissolving respective aluminium salts in deionised water and precipitating them with ammonium salts.
- the silica gel was prepared by precipitating a silica sol solution with nitric acid, and a alumina-silica gel was produced by dissolving aluminium salts in a silica sol solution and precipitation by adjusting the pH at values of between 5 to 9.
- the iron catalyst was prepared from aqueous salt solution of contain Fe2+, Fe3+ and Cu2+ with sodium carbonate solution, using the co-precipitation method.
- the mixture of cations was prepared by dissolving exactly 0.035 to 0.095 mole of copper nitrate, 0.60 to 1.50 mole of iron (III) chloride and 0.10 to 0.80 mole of iron (II) chloride in one liter of total solution.
- the precipitating solution was prepared by dissolving sodium bicarbonate or carbonate in an amount of 200 to 400 grams, in a volume of deionized water, equivalent to those of the cation solutions. Bath solution were heated up to 60 to 80 °C and added to a precipitation system containing 100 to 1000 ml of equivalently heated deionized water. The addition rate was adjusted in a way that the pH of the solution remained in the range of 4 to 10.
- the precipitates were filtered and washed thoroughly with deionized water for several times in order to remove the excess cations and anions.
- a suitable amount of potassium silicate and silica sol was added to the formed cake, in a way that the amount of potassium and silicon oxides do not exceed 1 to 3 and 15 to 25 percents by weight respectively.
- the formed catalyst was heated in 100 to 150 °C for 12 to 30 hours and was calcinated in 400 to 500 °C in an air flow for 4 to 8 hours.
- the atomic ratio of the formed catalyst with respect to iron was calculated using the [M/(M+Fe)] x 100 formulas where M represents metal oxide the atomic ratios for the prepared catalyst are: 100 Fe/3-10 CuO/0.5 - 3 K 2 O / 15-25 SiO 2
- HZSM5 catalyst with a silicon to Alumina ratio of 12-40 was prepared, using the method disclosed in the Egyptian patent No. 25 845.
- the catalyst according to the invention was prepared by physically mixing the prepared iron catalyst with HZSM5 Zeolite. A sieve with mesh size of 100 to 150 was used for adjusting the size.
- the catalyst was prepared in such a way that the eight percent of iron were present and between 10 to 30 and 70 to 90 weight percents of the catalyst are zeolite.
- a suitable binder is one of the important features.
- the silica gel was prepared by precipitation of silica sol by nitric acid and the silica-alumina gel was prepared by dissolving aluminium salts in a silica sol and then precipitation by controlled pH in a range of 6 to 8.
- oxidation and reduction method oxygen or air is used for burning hydrocarbons or coke remaining in or onto the catalyst.
- the reduction method the heavy hydrocarbons remaining on the catalyst as well as the coke placed on the active sites of the catalyst are converted to methane in a process called methanation making use of hydrogen.
- a water - gas shift reaction is observed in addition to the main process, which is caused by the absorption of carbon monoxide on the catalyst surface, the formation of surface carbides and chain growth.
- a water - gas shift reaction includes the reaction of carbon monoxide with water and the formation of carbon dioxide and hydrogen. This reaction is shown below: CO + H 2 O C0 2 + H 2
- hydrogen gas is produced during the water - gas shift reaction.
- This produced hydrogen can be used to regenerate the catalyst.
- the occurrence of the water-gas shift reaction among the total reactions is increased.
- Such an effect can be achieved by decreasing the space rate of the feed to 20 to 70 percents (based on the total volume of the reaction) and hence 90-99 percents of carbon monoxide is converted to hydrogen through the water-gas shift reaction.
- This provides enough hydrogen to regenerate the catalyst.
- the process to regenerate the catalyst by the produced hydrogen is performed at temperatures of the catalyst bed of between 280 to 300°C and under a pressure of 10 to 30 bars, after every 120 to 200 hours of the running process.
- the iron catalysts according to the invention can successfully be regenerated by such a process without any need to stop the process, i.e. the regeneration process can be achieved with simultaneously running the main process.
- the Fe-Cu - k catalyst was prepared by coprecipitation of iron and copper salts (Iron nitrates and copper nitrates), under controlled pH and temperature, with a final addition of potassium oxide.
- the prepared Fe catalyst was then physically mixed with the commercial HZSM5 Zeolite () by addition of silica - alumina gel (with a ratio of 70 to 10 percents of silica, and 30 to 90 percents of alumina) as an adhesive agent (in an amount of 10 to 15 weight%).
- the catalyst was formed to cylindrical pills with a diameter of about 4 mm and a length of 3 mm making use of a tableting press.
- the final catalyst was calcinated in airflow, at 450 °C.
- the activity of the catalyst was tested in a fixed-bed steel reactor of 2cm in diameter, which was furnished with a thermowall and a thermo couple.
- the flow of feed is controlled by mass - flow meters.
- the heating system consists of electrical heating jackets, each of which is controlled by a temperature controller.
- the temperature of the reactor outlet that passes through a pressurized container to collect the yielded liquid is lowered with a cooling system.
- the catalyst was moved to a reactor and finally prepared by reduction and carbonization stages. In the reduction stage, the catalyst stayed in a flow of nitrogen containing 5 to 8 percents by volume of hydrogen with a space rate of from 10 to 20 liters (g.Fe.h) -1 and was heated up to 250-270°C, with a temperature gradient of 10 °C /min.
- the regeneration by reduction of feed rate process was quickly performed, while the reaction was in process, after every 120 to 200 hours. During each regeneration reaction, the space velocity of the feed was reduced to 20, 45 and 70 percents of its initial values. As mentioned before, the initial values are 2 to 4 liters (g.Fe.h) -1 .
- the reaction was performed for 641 successive hours, during which the octane number of the product remained constant at about 95. Running the process under such conditions did not only prevent the catalyst from deactivation but also the capacity of the catalyst was increased, resulting in better conversion rates, becoming even better after each recycling step.
