摘要:
Disclosed are hybrid synthesis gas conversion catalysts containing at least one Fischer-Tropsch component and at least one acidic component deposited on a monolith catalyst support for use in synthesis gas conversion processes and methods for preparing the catalysts. Also disclosed are synthesis gas conversion processes in which the hybrid synthesis gas conversion catalysts are contacted with synthesis gas to produce a hydrocarbon product containing at least 50 wt % C5+ hydrocarbons. Also disclosed are synthesis gas conversion processes in which at least one layer of Fischer-Tropsch component deposited onto a monolith support is alternated with at least one layer of acidic component in a fixed bed reactor.

摘要:
Disclosed are a process and a system for synthesis gas conversion. The process includes contacting a synthesis gas feed of hydrogen and carbon monoxide having a H2/CO ratio from 0.5 to 3.0 with a hybrid catalyst of particles having a particle size from 50 to 500 μm and having at least one zeolite and a Fischer-Tropsch component wherein the ratio of zeolite to Fischer-Tropsch component is from 0.1:1 to 30:1 and the hybrid catalyst includes from 0.5 to 40 wt % Fischer-Tropsch component. The process is conducted in a compact heat exchange reactor having a set of reaction passages disposed between a synthesis gas feed header and a products header and a set of coolant passages disposed between a coolant inlet header and a coolant outlet header. The set of coolant passages conducts a coolant therethrough, and the set of reaction passages contains the hybrid catalyst therein and conducts synthesis gas and reaction products therethrough. The process is conducted at a temperature from 200 to 2800° C., a pressure from 5 to 40 atmospheres, a recycle ratio from 1 to 3, and a gaseous hourly space velocity less than 20,000 volumes of gas per volume of catalyst per hour. The effluent produced includes a hydrocarbon product containing at least 50 wt % C5+ hydrocarbons and less than 5 wt % C21+ hydrocarbons at a C5+ productivity from 0.05 to 2 gC5+/gcat/h.
