摘要: Pathways are disclosed for the production of liquid hydrocarbon products comprising gasoline and/or diesel boiling-range hydrocarbons, and in certain cases renewable products having non-petroleum derived carbon. In representative processes, a gaseous feed mixture comprising CO2 in combination H2 and/or CH4 (or other hydrocarbon source of H2) is converted by reforming and/or reverse water-gas shift (RWGS) reactions, optionally further in combination with Fischer-Tropsch (FT) synthesis and/or cracking. A preferred gaseous feed mixture comprises biogas or otherwise a mixture of CO2 and H2 that is not readily upgraded using conventional processes. Catalysts described herein have a high activity for catalyzing the reforming (including dry reforming) of CH4 and other light hydrocarbons (e.g., those having been produced via FT synthesis and recycled as light ends back to the process) as well as simultaneously catalyzing the RWGS reaction. These attributes allow for flexibility in terms of compositions that may be converted efficiently. Economics of small-scale operations may be improved, if necessary, using an electrically heated reforming reactor in the first or initial reforming stage or RWGS stage.

摘要: Processes for converting methane and/or other hydrocarbons to synthesis gas (i.e., a gaseous mixture comprising H2 and CO) are disclosed, in which at least a portion of the hydrocarbon(s) is reacted with CO2. At least a second portion of the methane may be reacted with H2O (steam), thereby improving overall thermodynamics of the process, in terms of reducing endothermicity (ΔH) and the required energy input, compared to “pure” dry reforming in which no H2O is present. Such dry reforming (reaction with CO2 only) or CO2-steam reforming (reaction with both CO2 and steam) processes are advantageously integrated with Fischer-Tropsch synthesis to yield liquid hydrocarbon fuels. Further integration may involve the use of a downstream finishing stage involving hydroisomerization to remove FT wax. Yet other integration options involve the use of combined CO2-steam reforming and FT synthesis stages (optionally with finishing) for producing liquid fuels from gas streams generated in a number of possible processes, including the hydropyrolysis of biomass.

摘要: Liquefied petroleum gas (LPG) synthesis catalyst systems are disclosed that provide activities for both alcohol (e.g., methanol) synthesis and in situ dehydration of the alcohol (e.g., methanol) to hydrocarbons, and particularly the LPG hydrocarbons propane and/or butane. The incorporation of a stabilizer such as platinum and/or yttrium (e.g., as yttria or yttrium oxide) can benefit these catalyst systems, particularly in terms of improving their activity and/or stability. Other advantages may be realized by the incorporation of promoters such as manganese (Mn), magnesium (Mg), and/or silicon (Si) into these catalyst systems, such as to improve selectivity to, and/or yield of, desired LPG hydrocarbons.
