Definitions

  • the gaseous and some of the liquid products are further hydrogenated in one or more reactors via fixed hydrogenation catalysts in order to increase the proportion of volatile products.
  • the object of the present invention was to develop a method in which external heat is not required during operation and the heat emission to the environment is as low as possible and to avoid a high pressure loss and deposits in the heat exchangers.
  • the invention is based on a process for the continuous production of hydrocarbon oils from coal by splitting pressurized hydrogenation in two stages, in which the first stage is grinding ground coal together with finely divided catalysts with an oil mixture, the slurry and the hydrogen under pressure from 200 to 700 bar heated to 380 to 440 ° C and passed through one or more reaction rooms and hydrogenated and separated the gaseous and liquid reaction products in hot separators from the solid and passed through one or more reaction rooms provided with fixed hydrogenation catalysts and hydrogenated again ( Gas phase) whereby the heat of the end products is transferred to the starting materials by heat exchange.
  • the invention relates to a method of this type, in which the heat on the coal-oil mixture and the hydrogen separately, indirectly and in three stages by heat exchangers, the heating of the coal-oil mixture in the temperature range from 290 to 340 ° C by adding a part of the hot liquid-solid hydrogenation residue and the entire condensate obtained at 390 to 410 ° C of the gas -Vaporous hydrogenation products.
  • a preferred embodiment of the method according to the invention consists in heating the starting materials coal pulp through line (1) with a circulating gas fraction of 0 to 25 vol.% And circulating gas in line (2), separated in 3 stages in tube bundle heat exchangers (10, 11, 12) and further partial flows can be found in (2., 4).
  • the circulating gas in line (2) is also heated in at least 5 stages in indirect heat exchangers (13, 14, 15, 16, 17).
  • Another possibility is to take other partial streams of the circulating gas from lines (2) and (4) and to add them to the coal slurry.
  • the entire heating heat is the flow of the hydrogenation products (7) removed.
  • the centrifugal pump (22) is used to convey intermediate separator condensate and the piston pump (21) is used to convey a partial flow of the residue through line (9).
  • the difficulties that arise when distributing highly segregated multiphase systems on parallel strands (tube bundles) are avoided with the small-bubble multiphase system.
  • the source area between 290 and 340 ° C can also be controlled by adding hot circulation and intermediate separating condensate. It is expedient to regeneratively heat the coal pulp up to the start of the source at 290 ° C and to bypass the source area by direct heat exchange with hot circulating product, since the swelling of the coal causes less equipment difficulties with direct heat exchange.
  • the suspension is advantageously mixed with a concentration of 40% solids.
  • concentrations of 0.38 to 0.58 solid / oil can be conveyed by the process according to the invention.
  • a particular technical effect of the method according to the invention can be seen in mastering the difficulty which arises from the property of the carbon particles to swell in the temperature range between 290 and 340 ° C. In this temperature range, swelling in the coal / oil mixture increases the toughness by a factor of approximately 100.
  • the swelling area can be avoided according to the invention if a concentration of ⁇ 40% solids in the mashing oil is set and the above-mentioned gradual heating is observed.
