After 40 years' R&D, Shengquan Group has developed "Shengquan method" integrated green straw refinery technology. The process is green, efficient and energy-saving, which solves the global problem of high-efficiency separation of cellulose, hemicellulose and lignin in straw, which realizes the high-quality utilization of the three components, and can produce hundreds of products. The cellulose part is used to produce pulp, dissolving pulp for fiber, nanocellulose, fuel ethanol, biomass graphene, etc., and use pulp to further produce degradable green products such as pulp molding; the hemicellulose part can not only produce furfural, but also xylose and L-arabinose, Furfural is used as raw material to further produce furan resin, which is linked with the foundry materials of the company. The lignin part can produce asphalt emulsifier, dye dispersant, degradable plastic bag, woody gum resin, military aviation kerosene, etc., that breaks the rely of fuel material and foreign monopoly to related products, and finally the residual ash content can be produced potassium fertilizer. This process can truly use all the components of straws and realize the simultaneous development of biomass chemical industry, petrochemical industry and coal chemical industry.
