Abstract: A method comprising contacting a carbon and hydrogen-containing solid fuel and a metal-based catalyst in the presence of oxygen to produce hydrogen gas and carbon monoxide gas, wherein the contacting occurs at a temperature sufficiently high to prevent char formation in an amount capable of stopping production of the hydrogen gas and the carbon monoxide gas is provided. In one embodiment, the metal-based catalyst comprises a rhodium-cerium catalyst. Embodiments further include a system for producing syngas. The systems and methods described herein provide shorter residence time and high selectivity for hydrogen and carbon monoxide.

Abstract: A method for suppressing dehydrogenation includes reacting an optionally functionalized olefin reactant in a metathesis reaction to form an olefin metathesis product; and providing a dehydrogenation suppression agent in admixture with (a) the olefin metathesis product and/or the optionally functionalized olefin reactant, and (b) a metal-containing material selected from the group consisting of residual metathesis catalyst, a hydrogen transfer agent, and a combination thereof, under conditions that are sufficient to passivate at least a portion of the metal-containing material. Methods of refining natural oils and methods of producing fuel compositions are also described.
