Pathways are disclosed for the production of liquefied petroleum gas (LPG) products comprising propane and/or butane, and in certain cases renewable products having non-petroleum derived carbon. In particular, a gaseous feed mixture comprising CO.sub.2 in combination with CH.sub.4 and/or H.sub.2 is converted by reforming and/or reverse water-gas shift (RWGS) reactions, further in combination with LPG synthesis. A preferred gaseous feed mixture comprises biogas or otherwise a mixture of CO.sub.2 and H.sub.2 that is not readily upgraded using conventional processes. Catalysts described herein have a high activity for reforming (including dry reforming) of CH.sub.4, as well as simultaneously catalyzing RWGS. These attributes improve the management of CO.sub.2 that is input to the disclosed processes, particularly in those utilizing recycle operation to increase overall CO.sub.2 conversion. 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.

A method that combines a fuel cell with a Gas Recovery Unit (GRU) to a methanol plant to produce methanol at near zero GHG emissions. The fuel cell generates steam, carbon dioxide and electricity. A GRU unit condenses, separates, recovers, pressurizes and reheats the fuel cell anode exhaust stream. The GRU prepares a stream of natural gas and steam to feed the fuel cell anode and a stream of carbon dioxide and air to feed the fuel cell cathode. The GRU also prepares streams of carbon dioxide and steam as reactants for the stoichiometric mixture with natural gas to produce synthesis gas in an electric catalytic reformer at a methanol plant. The electric catalytic reformer uses electricity, steam and/or carbon dioxide reactants produced by the fuel cell to produce synthesis gas for conversion to methanol with low GHG emissions.
