    Abstract: 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.

    Abstract: A method is provided for converting synthesis gas to liquid hydrocarbon mixtures useful as distillate fuel and/or lube base oil. The synthesis gas is contacted with a synthesis gas conversion catalyst comprising a Fischer-Tropsch synthesis component in an upstream catalyst bed thereby producing an intermediate hydrocarbon mixture containing olefins and C21+ normal paraffins. The intermediate hydrocarbon mixture is subsequently contacted with a hydroisomerization catalyst and an olefin saturation catalyst, thereby resulting in a product containing no greater than about 25 wt % olefins and containing no greater than about 5 wt % C21+ normal paraffins. The hydroisomerization and olefin saturation catalysts may be in separate beds or mixed in a single bed downstream of the synthesis gas conversion catalyst.

    Abstract: Disclosed is a process for converting synthesis gas to liquid hydrocarbon mixtures useful in the production of fuels and petrochemicals. The synthesis gas is contacted with at least two layers of synthesis gas conversion catalyst and at least two layers of acidic hydrocracking catalyst in an alternating layer arrangement within a single reactor tube wherein each synthesis gas conversion catalyst layer is followed by a layer of hydrocracking catalyst. The process is conducted within a single reactor at an essentially common reactor temperature and an essentially common reactor pressure. The process provides a high yield of naphtha range liquid hydrocarbons and a low yield of C21+ normal paraffins.
