Recently, two projects of national science and technology support plan of biomass energy have obtained staged achievements, namely "R & D and Application of Biomass Low Energy Consumption Solid Molding Fuels Equipment" and "Development and Demonstration of Key Technology of Non-grain Fuel Ethanol". These two new technologies are expected to play a significant role in promoting the development of new energy in rural areas. The overall implementation of the "12th Five-year" National Science and Technology Supporting Plan Project "R & D and Application of Biomass Low Energy Consumption Solid Molding Fuels Equipment" (Project No. 2012BAD30B00) organized by the State Forestry Administration has progressed smoothly and achieved initial results. The project has developed medium and low temperature heat treatment technology of biomass selective, innovatively put forward the technology of catalyzing the pyrolysis of cellulosic / biomass co-production of LGO and molding fuel with titanium-based solid superacid; developed the key components of the split type new pressure roller molding equipment, A new type of closed-cycle oil-cooled biomass pellet molding machine, a low-energy biomass pressure compacting equipment, and the like. The integration of the solid molding fuel production technology and the establishment of an efficient, scientific and orderly raw material storage and storage Mode, industrialized cleaner production mode and industrial development mode, the life-cycle energy consumption and environmental emission analysis model for briquette fuel has been established for the first time. Project achievements have been achieved large-scale promotion and application. In Jilin NongShui poplar forest Township to establish an annual output of 10,000 tons of pellet fuel plant, new pellet fuel molding equipment 10 sets / sets. The biomass cooking stoves and biomass cooking stoves have been popularized 1000 sets, the economic benefits have reached 2.5 million yuan, the annual consumption of molding fuel 5000 tons, the emission reduction of CO26500 tons, SO215 tons, smoke and dust 37.5 tons, NO25 Ton, can directly replace the coal for rural families cooking and heating, effectively improving the rural atmosphere, to solve some of the rural areas of high energy consumption, energy shortages and other issues; built Yang Louzhen, Wenquan Zhen, Wangzhai Township and Temple 4 demonstration fuel production sites in the countryside, forming 60,000 tons / year of molding fuel production capacity, the first half of the production of 30,000 tons of molding fuel, sales revenue of 15 million yuan; developed a new type of biomass fuel molding machine and system equipment, at Wuwei County in Anhui Province to promote the use of new two straw molding fuel processing point, the supply of Salt Red Sifang biomass forming fuel combustion power generation projects. The progress and achievements of the research on the new duckweed cultivation by National Science and Technology Support Program jointly undertaken by Chengdu Institute of Biology, Chinese Academy of Sciences and other units jointly undertaken by the National Key Project of Development and Demonstration of Key Technologies for Non-grain Fuel Ethanol (2011BAD22B03) were carried out. The subject first screened and obtained seven high-starch duckweed strains, and established a stable high-duckweed duckweed culture system. The mechanism of rapid duckweed accumulation was clarified from multiple research levels, and duckweed was established as a high-quality bioenergy source The important position of plants, for the first time elucidated the low duckweed lignin content and the reasons for the high content of flavonoids. Second, the establishment of high-starch duckweed scale culture technology and duckweed wastewater treatment technology system. Large scale duckweed has been developed on the scale of culture technology, in the field environment to achieve the use of wastewater culture high-starch duckweed raw materials. Kunming, Yunnan and Weiyuan, Sichuan, respectively, to establish direct use of waste water duckweed training base has been achieved per mu surface water yield duckweed up to 800 kg, duckweed biomass up to 3 tons / acre year. The third is the establishment of duckweed energy conversion system, developed duckweed as raw material biological liquid fuel conversion technology system, achieved high starch duckweed as raw material, ethanol concentration up to 7% (v / v) above, fermentation efficiency Reached 90%. Butanol fermentation concentration of up to 11.65g / L, the total solvent reached 18.65g / L, the technical indicators have reached international standards.
