NOVELTY - Biomass composition comprises biomass in a particle form (653) created in a pretreatment step that occurs prior to a biomass gasification reaction or torrefaction process, where the biomass initially has a bulk structure including organic polymers of lignin that surrounds many cellulose fibers in a fiber bundle. The bulk structure of the biomass is: stripped apart to at least partially separate an outer layer of lignin in the biomass from cellulose fibers; and/or internally blown apart to create fragments of fiber bundle, in pretreatment step that uses at least moisture, pressure, and heat.    USE - The biomass composition is useful in a biomass gasification reaction where larger organic molecules making up the biomass are decomposed into smaller molecules to create syngas components, including hydrogen and carbon monoxide, as a product of the biomass gasification reaction and/or a torrefaction process (claimed).    ADVANTAGE - The composition can be produced using the pretreatment step which is easy, rapid and economic, by consuming less amount of energy.    DETAILED DESCRIPTION - Biomass composition comprises biomass in a particle form (653) created in a pretreatment step that occurs prior to a biomass gasification reaction or torrefaction process, where the biomass initially has a bulk structure including organic polymers of lignin that surrounds many cellulose fibers in a fiber bundle. The bulk structure of the biomass is: stripped apart to at least partially separate an outer layer of lignin in the biomass from the cellulose fibers; and/or internally blown apart to create fragments of the fiber bundle, in the pretreatment step that uses at least moisture, pressure, and heat to liberate and expose the cellulose fibers to be able to react in a two-stage sequence during biomass gasification reaction or torrefaction process rather than reacting in a repeating cycle of multiple layers of lignin followed by the cellulose and hemicelluloses. The biomass in particle form has a length to thickness aspect ratio on average of less than 300 to 1, a thickness on average of less than 100 mu thick and a length on average of less than 3000 mu .
