Aspects of the invention relate to improvements in the flexibility with which oxygen and hydrogen, for example from electrolysis, may be supplied to processes having both gasification and methanation steps, as well as improvements in how such processes may be operated in response to variations in carbonaceous feeds. Offsets, between the ideal quantity of hydrogen and the quantity available from a given source may be compensated for by adjusting one or more operations of the process, and in particular such operation(s) that ultimately impact the quantity of CO and/or CO.sub.2 available downstream of the gasifier for conversion to methane in an RNG product stream.

A fuel production system includes a gasification unit including a gasification furnace that gasifies biomass feedstock to produce a syngas; a liquid fuel production unit that produces a liquid fuel from the syngas produced by the gasification unit; an electrolysis unit that produces hydrogen from water using electric power generated using renewable energy; a hydrogen tank that stores the hydrogen produced by the electrolysis unit; a remaining hydrogen amount determining section that determines the amount of hydrogen remaining in the hydrogen tank; a hydrogen supply unit that supplies the hydrogen from the hydrogen tank to the gasification unit; and a control unit that performs a hydrogen consumption increasing control to reduce the H.sub.2/CO ratio of the syngas produced by reaction in the gasification furnace and to increase the amount of hydrogen supplied by the hydrogen supply unit, when the remaining amount of hydrogen is more than a predetermined amount.

The present invention relates to a method of optimization for continuous combustion systems, which reduces fuel consumption, exhaust emissions and particulate matter. The operating principle is based on the introduction of small amounts of hydrogen in the fuel intake duct of the system, or preferably along the continuous burning chamber, with the aim of optimizing the burning of traditional fuels, improving the parameters of the combustion reaction, the effect of the process in question will increase the temperature of the walls of the chamber, ensuring re-ignition and a more complete combustion and consequently reducing the required fuel flow feed. This optimized combustion will increase the combustion efficiency and reduce its environmental impact.

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.

A system and method for converting (dry reforming) natural gas (methane) and carbon dioxide via reformer catalyst in a dry reformer into syngas including carbon monoxide and hydrogen, and discharging the syngas to a Fischer-Tropsch (FT) reactor. Supplemental hydrogen is generated via water electrolysis and added to the syngas in route to the FT reactor to increase the molar ratio of hydrogen to carbon monoxide in the syngas. The syngas may be converted via FT catalyst in the FT reactor into FT waxes.
