Abstract

See full text

An integrated plant that includes a steam explosion process unit and biomass gasifier to generate syngas from biomass. A steam explosion process unit applies a combination of heat, pressure, and moisture to the biomass to make the biomass into a moist fine particle form. The steam explosion process unit applies steam with a high pressure to heat and pressurize any gases and fluids present inside the biomass to internally blow apart the bulk structure of the biomass via a rapid depressurization of the biomass with the increased moisture content. Those produced moist fine particles of biomass are subsequently fed to a feed section of the biomass gasifier, which reacts the biomass particles in a rapid biomass gasification reaction to produce syngas components.
