    摘要: The present invention concerns a process for the synthesis of hydrocarbons from a feed comprising synthesis gas, in which a solid catalyst comprising cobalt is used in a three-phase reaction section operated such that said catalyst is maintained in suspension in a liquid phase by movement of a gas phase from the bottom to the top of said reaction section, said process comprising an external loop for separating waxes, characterized in that: 1) the theoretical ratio PH2O:PH2 in the external loop for separating waxes is determined using the following calculation: PH2O:PH2 theoretical=Cv/(R1−Rft×Cv) where Cv=(COinlet−COdegas)/COinlet R1=H2 inlet/COinlet Rft=(H2 inlet−H2 degas)/(COinlet−COdegas) 2) if the theoretical ratio PH2O:PH2 determined in step 1) has a value of Rthreshold or higher, the temperature in the degassing means for the external loop for separating waxes is reduced, 3) steps 1) to 2) are repeated until the theoretical ratio PH2O:PH2 has a value strictly less than Rthreshold, where Rthreshold is in the range 0.1 to 1.1.

    摘要: A process for converting carbonaceous materials or light hydrocarbon gases into products comprising predominately C5+ hydrocarbons. The process converts the feedstock into synthesis gas comprising hydrogen and carbon monoxide and then uses the Fischer-Tropsch reaction to produce heavy hydrocarbons. A small excess of hydrogen is produced in the syngas generator or by water gas shift for use in product upgrading and for blending with Fischer-Tropsch tail gas for recycle back to syngas generation. A portion of the Fischer-Tropsch tail gas is used as fuel, thus purging combustible light gases and CO2 from the tail gas. Hydrogen rich purge gas is blended into the remaining tail gas resulting in a recycle stream that is returned to the syngas generator. The tail gas components are therefore efficiently used to produce more products.

    摘要: A synthesis gas conversion process and system are disclosed. Fresh syngas from a methane reformer is used as a sweep zone gas feed which is caused to flow across a water permselective membrane in a membrane reactor. The water permselective membrane is adjacent a synthesis gas conversion reaction zone in which synthesis gas is contacted with a catalyst and converted to effluent including water. Water is removed from the reaction zone through the membrane and passes out of the reactor with the sweep zone gas. The water is then removed from the sweep zone gas forming a modified gas feed which is fed to the reaction zone. The modified gas feed has a preferred H2/CO ratio to feed into the reaction zone.
