1. A trigeneration facility, comprising:
a desulfurization unit to remove sulfur from a hydrocarbon feed stream forming a desulfurized feed stream, the desulfurization unit comprising a desulfurization catalyst, the desulfurization catalyst comprising a gamma alumina based support, at least one catalytic metal from group VI, at least one catalytic metal from group VIII, and at least one dopant selected from a group consisting of boron, phosphorous, halogen, and silicon;
a pre-reformer to convert the desulfurized feed stream to a methane rich gas, the pre-reformer comprising a steam reformer comprising a nickel catalyst;
a membrane separator to remove at least a portion of hydrogen from the methane rich gas in a permeate, the membrane separator comprising a water-gas shift catalyst to increase an amount of hydrogen in the methane rich gas;
a pressure swing adsorption unit to purify hydrogen in the permeate, providing a purified stream;
a compressed hydrogen stream of about 400 bar to about 900 bar, wherein the compressed hydrogen stream is a fuel stream to a fuel cell vehicle from the purified stream; and
a solid oxide fuel cell (SOFC) to generate electrical power and heat from a retentate from the membrane separator, wherein the retentate comprises methane.
