A biomass conversion system is disclosed. The system comprises a syngas generator, a cleanup engine and a power producing engine. The power producing engine is coupled to a load, such as an electrical generator. Methods of controlling the power producing engine in response to changes in load are disclosed. In certain embodiments, the air-to-fuel ratio, spark timing, and/or recirculation gases are varied to change the power of the power producing engine. In other embodiments, the power producing engine is throttled by limiting the amount of clean syngas that enters the engine.

A method of producing liquid fuel and/or chemicals from a carbonaceous material entails combusting a conditioned syngas in pulse combustion heat exchangers of a steam reformer to help convert carbonaceous material into first reactor product gas which includes carbon monoxide, hydrogen, carbon dioxide and other gases. A portion of the first reactor product gas is transferred to a hydrogen reformer into which additional conditioned syngas is added and a reaction carried out to produce an improved syngas. The improved syngas is then subject to one or more gas clean-up steps to form a new conditioned syngas. A portion of the new conditioned syngas is recycled to be used as the conditioned syngas in the pulse combustion heat exchangers and in the hydrocarbon reformer. A system for carrying out the method include, a steam reformer, a hydrocarbon reformer, first and second gas-cleanup systems, a synthesis system and an upgrading system.
