A method of generating hydrogen-enriched fuel gas and carbon dioxide comprising converting hydrocarbon molecules from a gaseous hydrocarbon feed stream into hydrogen and carbon dioxide, separating the hydrogen and carbon dioxide, blending the hydrogen back into the gaseous hydrocarbon feed stream to generate a hydrogen-enriched fuel gas, and utilizing the carbon dioxide for storage or sequestration. A system for generating hydrogen-enriched fuel gas and carbon dioxide comprising an inlet handling system, a syngas and water-gas shift system, a water-gas compression system, a carbon dioxide recovery system, a dehydration system, and a carbon dioxide compression system.

Embodiments of the invention relate to processes and apparatus for the washing and recovery of metal-containing catalyst solids in a form suitable for reclamation. More specifically, a catalyst recovery process comprises removing an organic residue with a washing medium from a metal-containing catalyst solids, recovering washed solids, and treating the washed solids under oxidative conditions to form non-reactive solids. The treatment oxidative conditions may be effective to convert the metal(s) into an oxide form and/or may facilitate the removal of remaining organic residue from the washed solids. The treatment of the washed solids may comprise calcination. In some embodiments, the metal-containing catalyst solids may be recovered from a slurry stream, and the process further comprises passing the slurry stream though a separation unit to obtain a catalyst-enriched retentate slurry. In some embodiments, the organic residue comprises a hydrocarbon wax, and the solid catalyst is a hydrocarbon synthesis particulate catalyst.
