Patent number: 8636923Abstract: 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.Type: GrantFiled: October 12, 2011Date of Patent: January 28, 2014Assignee: Enerkem, Inc.Inventors: Antonin Paquet, Martin Gagnon, Esteban Chornet
