    摘要: The present invention relates to a process for producing ethylene and propylene from syngas, the process comprising the steps of a) contacting syngas (2) with a first catalyst composition to obtain a first product stream (3) comprising ethylene, propylene and aliphatic hydrocarbons having 4 or more carbon atoms, b) splitting the first product stream (3) into a second product stream (5) comprising at least 90% of said aliphatic hydrocarbons having 4 or more carbon atoms and a third product stream (4) comprising ethylene and propylene, 3) separating ethylene and propylene in the third product stream so as to form a first ethylene stream (17) and a first propylene stream (16) and d) converting the second product stream (5) into a fourth product stream (8) comprising ethylene and/or propylene.

    摘要: The invention relates to synthesis of liquid C5 and higher hydrocarbons from CO and H2 according to the Fischer-Tropsch synthesis. An object is to provide high syngas conversion rate, minimum content of waxes in the products, high content of C10-C20 fractions per pass within a single reactor and avoidance of use of expensive catalyst components. The claimed method for preparing synthetic liquid hydrocarbons by catalytic conversion of a syngas according to the Fischer-Tropsch synthesis comprises sequential passing the reaction mixture through at least four layers of a multilayer fixed bed of granulated catalysts, wherein a first layer in the direction of passing the reaction mixture comprises a cobalt Fischer-Tropsch synthesis catalyst that provides occurring the Fischer-Tropsch synthesis at Anderson-Schulz-Flory factor of 0.67 to 0.96, a second layer in the direction of passing the reaction mixture comprises a traditional cobalt Fischer-Tropsch synthesis catalyst that provides occurring the Fischer-Tropsch synthesis at Anderson-Schulz-Flory factor of 0.82 to 0.96, a third layer in the direction of passing the reaction mixture comprises not less than 30% of H-form zeolite, and a lowermost layer comprises a traditional cobalt Fischer-Tropsch synthesis catalyst that provides occurring the Fischer-Tropsch synthesis at Anderson-Schulz-Flory factor of 0.82 to 0.96. The cobalt Fischer-Tropsch synthesis catalyst of the first layer has thermal conductivity not less than 4 watt/m·K and comprises not more than 10% of skeleton cobalt to decrease heat generation intensity in the front layer and not less than 20% of H-form zeolite.
