The present invention provides a system and method for producing hydrocarbons from biomass. The method is particularly useful for producing substitute natural gas from forestry residues. Certain disclosed embodiments convert a biomass feedstock into a product hydrocarbon by fast pyrolysis. The resulting pyrolysis gas is converted to the product hydrocarbon and carbon dioxide in the presence of hydrogen and steam while simultaneously generating the required hydrogen by reaction with steam under prescribed conditions for self-sufficiency of hydrogen. Metha...
1. A method, comprising: pyrolyzing biomass to produce a pyrolysis gas and char;hydrogasifying the pyrolysis gas in the presence of a catalyst and hydrogen produced by a hydrogen generator powered by a renewable energy source, to produce a gas mixture;separating the gas mixture into a substitute natural gas stream and a residual gas stream. 2. The method of claim 1, wherein the substitute natural gas stream comprises methane. 3. The method of claim 1, wherein the residual gas stream comprises water. 4. The method of claim 1, wherein the residual gas stre...
