    摘要： A process for producing synthesis gas, or syngas, from biomass. The process comprises contacting biomass with oxygen, or oxygen and steam, in an amount effective to oxidize the biomass and to heat the biomass to a temperature to no greater than 750° C. At least one combustible material also is contacted with oxygen and steam to heat the at least one combustible material to a temperature of at least 1,100° C., to provide a hot gas derived from the oxidized combustible material. The latter maybe residual products derived from the process itself as char, tar, or hydrocarbons. The oxidized biomass then is contacted with the hot flue gas to heat the biomass to a temperature of at least 900° C., thereby producing synthesis gas. The synthesis gas then is recovered. Such process provides a method of providing heat for producing synthesis gas without consuming a portion of the synthesis gas to provide such heat, thereby providing an increased yield of synthesis gas.

    摘要： Syngas is formed by combining a carbon source with steam at an elevated temperature in a generally horizontal reactor. The heat for the reaction is provided by a stoichiometric combustion nozzle at a first end of the horizontal reaction chamber. The carbon source is deposited downwardly into the reaction chamber where it combines with a flowing stream of hot gas formed from the stoichiometric combustion in combination with steam and additional oxygen, if necessary. This flowing stream of gas reacts with the deposited carbon feed source and is directed to a cyclone separator where the formed syngas is recovered from an upper portion of the separator and any formed ash is directed into a collection tank.

    摘要： The invention relates to a method for the gasification of carbonaceous materials in the form of solid particles. The inventive method comprises the following steps consisting in: heating a gaseous mixture formed by a feed gas and water vapor in a heater (1); bringing the particles of the carbonaceous materials into contact with the heated gaseous mixture in a pressurized gasification reactor (2), with the formation of a raw reaction gas and unburnt ash; separately supplying the heater with (i) water vapour and (ii) the aforementioned feed gas; taking separate samples from the heater of the gaseous mixture (at point 13) and of part of the feed gas in the dry state (at point 16); and injecting into the gasification reactor said dry feed gas and a gas forming therewith a fuel mixture in the ash.
