The present invention describes a process and catalysts for the conversion of a light hydrocarbon and carbon dioxide input stream into high quality syngas with the subsequent conversion of the syngas into fuels or chemicals. In one aspect, the present invention provides an efficient, solid solution catalyst for the production of a carbon containing gas from carbon dioxide and light hydrocarbons. The catalyst comprises a single transition metal, and the transition metal is nickel.

Operation of a thermochemical regenerator at a controlled ratio of recycled flue gas to reforming fuel provides formation of fuel species that permit a higher flame temperature upon combustion of the resulting combustible mixture.

A method upgrading waste to produce fuel can include: introducing a hydrocarbon feed stream into a 450 C. to 1050 C. coking zone of a reactor containing a fluidized bed of coke particles maintained at coking temperatures to produce a vapor phase hydrocarbon product while coke is deposited on the coke particles; allowing the coke particles to pass downwards to a stripper section of the reactor; introducing a steam stream into the stripper section; transferring the coke particles from the stripper section to a gasifier/burner; contacting the coke particles in the gasifier/burner an oxygen-containing gas in an oxygen-limited atmosphere at 850 C. to 1200 C. to heat the coke particles and form a fuel gas product that comprises carbon monoxide and hydrogen; recycling the heated coke particles from the gasifier/burner to the coking zone of the reactor; and introducing at least one waste stream to the reactor and/or the gasifier/burner.
