| 摘要 |
The invention relates to a method for producing liquid hydrocarbons from gas that has been produced by partial oxidation of natural gas or liquid and solid organic fuels, especially biomasses such as wood, straw, energy plants and/or organic waste and residues, by partial autothermic or allothermic oxidation, with subsequent gas purification and preparation, e.g. C0 conversion and C0<SUB>2</SUB> washing in a synthesis gas production installation, and is then converted to liquid hydrocarbons on catalysts. According to the invention, a first gas accumulator operating at a pressure above the process pressure of the synthesis stage is arranged between the synthesis gas production and synthesis process stages, and a second gas accumulator operating at a pressure below the process pressure of the synthesis stage is arranged between the stages of the condensation of the liquid products, carried out following the synthesis, and of the purge gas evacuation. Said gas accumulators are interconnected by means of a circuit compressor and a pressure reduction such that, in the event of a pressure drop in the supply of fresh synthesis gas from the synthesis gas production stage to the first gas accumulator, the pressure of the gas in the synthesis stage remains constant or only drops according to the material conversion in the synthesis stage, when the evacuation opening for the purge gas from the second gas accumulator is open or closed. |
