Research progress on high-efficient transformation and utilization of cellulose biomass

Recently, the "863" project has made progress in the field of "high-efficiency conversion and utilization of cellulosic biomass" in the field of modern agricultural technology. The chief expert of the project, Ma Longlong, director of the Guangzhou Institute of Energy Research of the Chinese Academy of Sciences, introduced the project in the marginal land energy grass molecular breeding. New germplasm creation, key technologies for efficient preparation of biogas from energy grass, high-efficiency pretreatment technology and equipment for lignocellulosic materials, radiation-induced and cellulosic degradation of thermophilic thermostable cellulase, and aqueous catalytic synthesis of biomass The development of key technologies such as bio-aviation fuel technology, high-temperature biorefinery of biomass liquid fuels, advanced biocracking of bio-mass, bio-efficient catalytic pyrolysis directed gas preparation, and high-efficiency biomass fixed-bed gasification power generation are progressing smoothly.

The research team of Guangzhou Institute of Energy, which undertakes the project's project, developed a new biological aviation fuel technology for the synthesis of biological materials for water from birth. It successfully converted agricultural waste such as corn stalks and sorghum stalks into high-quality biological aviation fuel products, and built the world’s first 100 ton Aqueous phase synthesis of biological aviation fuel pilot test demonstration system, and achieve continuous and stable production, testing by the State Oil Testing Center, to reach aviation fuel quality standards, the overall international leading technology level. The team responsible for the study of efficient energy anaerobic fermentation to prepare natural gas, using hybrid Pennisetum and other energy plants as raw materials, integrated optimization of pretreatment, two-stage anaerobic fermentation gas, biogas upgrading and comprehensive utilization of fermentation residues. The module technology and equipment form a pilot platform for the entire industrial chain of “energy grass cultivation→anaerobic fermentation→products (natural gas, organic fertilizer)”. Through the operation, adjustment and optimization of the project, the energy plant preparation for China Biogas provides reliable theoretical basis and practical experience.

The project “High-efficiency Conversion and Utilization of Cellulosic Biomass” has provided technical support for the efficient and comprehensive utilization of agricultural and forestry waste.
