摘要:
A process is disclosed for converting a feed comprising synthesis gas to liquid hydrocarbons within a single reactor at essentially common reaction conditions. The synthesis gas contacts a catalyst bed comprising a mixture of a synthesis gas conversion catalyst on a support containing an acidic component and a dual functionality catalyst including a hydrogenation component and a solid acid component. The hydrocarbons produced are liquid at about 0° C., contain at least 25% by volume C10+ and are substantially free of solid wax.
摘要:
A method for performing synthesis gas conversion is disclosed which comprises contacting synthesis gas with a hybrid Fischer-Tropsch catalyst formed by impregnating a ZSM-12 zeolite extrudate using a solution, for example, a substantially non-aqueous solution, comprising a cobalt salt and activating the impregnated zeolite extrudate by a reduction-oxidation-reduction cycle. The method results in reduced methane yield and increased yield of liquid hydrocarbons substantially free of solid wax.

摘要:
A method is provided for converting synthesis gas to liquid hydrocarbon mixtures useful as distillate fuel and/or lube base oil containing no greater than about 25 wt % olefins and containing no greater than about 5 wt % C21+ normal paraffins. The synthesis gas is contacted with a synthesis gas conversion catalyst comprising a Fischer-Tropsch synthesis component and an acidic component in an upstream catalyst bed thereby producing a wax-free liquid containing a paraffin component and an olefin component. The olefin component is saturated by contacting the liquid with an olefin saturation catalyst in a downstream catalyst bed.

摘要:
Processes and systems are provided for converting synthesis gas containing a mixture of H2 and CO to liquid hydrocarbon products having a cloud point less than about 15° C. The systems utilize at least one Fischer-Tropsch reactor containing hybrid Fischer-Tropsch catalyst with cooling and separation of reactor effluent following each reactor. The low cloud point indicates that the amount of wax in the hydrocarbon products is minimized relative to conventional Fischer-Tropsch conversion. Accordingly, more economical systems can be built and operated because equipment associated with wax removal or wax treatment can be reduced or eliminated.
摘要:
A process is disclosed for converting synthesis gas to a liquid hydrocarbon mixture useful as distillate fuel and/or lube base oil which is substantially free of solid wax. A synthesis gas feed is contacted with a synthesis gas conversion catalyst in an upstream bed and a hydroisomerization catalyst containing a metal promoter and an acidic component in a downstream bed within a single reactor at essentially common reaction conditions. A Fischer-Tropsch wax is formed over the synthesis gas conversion catalyst and said wax is subsequently hydroisomerized over the hydroisomerization catalyst, thereby resulting in a liquid hydrocarbon mixture having a desirable product distribution.

摘要:
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.
