A method of gasifying carbonaceous material is described. The method comprises a first step of pyrolyzing and partially gasifying the carbonaceous material to produce volatiles and char. The volatiles and the char are then separated and, subsequently, the char is gasified and the volatiles are reformed. The raw product gas is then finally cleaned with char or char-supported catalysts or other catalysts.

Method of gasifying carbonaceous material and a gasification system

A pyrolysis plantcomprises a grinding pyrolyzer, being a machine or apparatus in which both particle size reduction and pyrolysis occur simultaneously. Plantalso comprises a bin (hopper)for holding wet particulate biomass feedstock. Chuteleads from the binto a biomass dryerwhich reduces moisture content of the feedstock as low as possible, e.g., to below about 10. Dried feedstock is conveyed from dryervia lineto a dried biomass feedstock hopper. Dried feedstock is fed from hopperinto a chutewhich leads to an inlet trunnionof grinding pyrolyzer. A discharge trunnionof grinding pyrolyzerleads to a char holderfor collecting char particles and a condensation trainfor condensing vapor generated by the pyrolysis to produce oil.
