NOVELTY - Co-producing and preparing bamboo material biomass fuel and bamboo pulp, by (a) subjecting bamboo raw material to hot water extraction to obtain hemicellulose extract, (b) separating hemicellulose and lignin extract, and the filament material, (c) preparing cellulose extraction and bamboo pulp, adding alkali, and filtering hemicellulose and lignin degradation solution to obtain bamboo pulp, (d) separating hemicellulose, and subjecting to saccharification, and (e) crushing bamboo leaves, mixing residual liquid with cellulose to obtain product, and drying product.    USE - The method is useful for co-producing and preparing bamboo material biomass fuel and bamboo pulp.    ADVANTAGE - The method is cost-effective, improves utilization rate of bamboo resource, has commercial benefits and reduces environmental pollution.    DETAILED DESCRIPTION - Method for co-producing and preparing bamboo material biomass fuel and bamboo pulp, involves (a) obtaining bamboo raw material cutting cleaning dust, extracting hemicellulose from the bamboo material using hot water, filtering the extract, and further extracting the filtrate, and subjecting filtrate to extrusion to obtain a sheet-type material extrusion, (b) extracting the sheet-type material extrusion, kneading the obtained product into thread material, separating hemicellulose and lignin extract from obtained material, and filament material, adding alkali and hydrogen peroxide solution to the product, degrading residual hemicellulose and lignin continuously, and treating the filament material, (c) adding alkali into the treated filament material, heating the obtained product, washing the reacted material, and filtering the degraded hemicellulose and lignin to obtain bamboo pulp, (d) mixing hemicellulose extract of step (a), hemicellulose and lignin extract of step (b), the hemicellulose and lignin degradation solution of step (c) to obtain mixed solution, separating the hemicellulose from the mixed solution to obtain residual liquid, subjecting the residual liquid to saccharification, inoculating microzyme to the obtained material for fermenting and processing hemicellulose, and concentrating the obtain product using ethanol to obtain ethanol by distillation process, and (e) mixing bamboo raw material after cutting the remaining elongate and tail of the bamboo leaves after crushing, and residual liquid of step (d) to obtain a mixture, extruding the mixture to-be in form and drying the mixture to obtain biomass fuel particles.
