Biochemical technology is an effective means for China's chemical industry to achieve transformation of production methods, product structure adjustment and clean and efficient manufacturing. During the “Eleventh Five-Year Plan†period, China increased its investment in scientific research in the field of biochemical technology and achieved important results in the areas of biocatalyst-oriented transformation, large-scale biocatalytic technology systems, biomaterials, and bioenergy. At present, China has formed a modern industrial cluster of bio-industries, and the industries of bio-plastics, bio-energy, and bio-based chemical materials are rapidly developing.
During the "Eleventh Five-Year Plan" period, China has been synchronized with the world advanced level in the field of cellulosic ethanol research and development, and has established a number of large-scale demonstration projects for fuel ethanol and biodiesel. China's first 10,000-ton fiber ethanol demonstration plant started operation in Henan Tianguan Group Corporation in 2008; Tianjin University and Guangxi Zhongliang built the world’s largest single 200,000-ton/year cassava fuel ethanol plant; Changchun Dacheng Group implemented a corn starch sugar, a series of modified starch and polyol development and industrialization demonstration projects. It has built a 200,000-ton production line for the first time in the world. Jilin Song Original Handan Chemical Co., Ltd. is relying on the technology of the Chinese Academy of Sciences Institute to build an international leader. 300,000 tons / year straw refining industrial production line. In the field of biodiesel produced by microalgae, the Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences, has screened oil-producing microalgae and algae strains, which has greatly reduced costs.
In the field of biocatalyst-oriented reformation and enzymatic biodiesel production, Beijing University of Chemical Technology developed a green chemical synthesis process using lipase as a catalyst, developed a new lipase immobilization technology, and successfully achieved the esterification industry in China. Production. At present, China's first enzymatically-produced biodiesel industrialization project with an independent intellectual property right in China has started in Qinhuangdao.
During the “Eleventh Five-Year Plan†period, China’s research and development of biomass-based macromolecules and new material technologies and products have also yielded significant results. Originally, a lignocellulose organic acid separation technology system was created, and new functional materials such as high-performance ion exchange resins have been successfully developed. In the field of polylactic acid, domestically produced polylactic acid with properties that meet the standards of similar foreign products has been successfully produced using the core technology of green solvent-free bulk polymerization developed by China and the production line of polylactic acid; in terms of PHA, China's current total annual production capacity exceeds 15,000. Tons, the PHA industrialization variety and output are all in the leading position in the world, and the 10,000-ton PHA unit has been successfully tested.
In the field of large-scale production of biocatalytic technology, the new technologies and new products for the application of microbial pesticide fermentation, completed by the Chinese Academy of Agricultural Sciences, have significantly increased the fermentation level of avermectin, Bt, and mesitulin. Zhejiang University of Technology developed Jinggangmycin biocatalytic method for large-scale production of jingololamine, realizing the large-scale production of jingokamylamin and high-purity Jinggangmycin; the production of microorganisms by the microbial fermentation method developed by the Institute of Microbiology, Chinese Academy of Sciences The chain dibasic acid technology has made China the only country in the world that can use the biosynthetic process to produce long-chain dicarboxylic acids.
In the field of creation of clean conversion media, Tsinghua University has developed a complete set of equipment for integrated membrane bioreactors. The new wastewater treatment technology, which combines membrane separation technology with biotechnology, can realize the transition from wastewater treatment to reclaimed water. The low-energy membrane-bioreactor and membrane module unit developed by the project has significantly improved the operating flux. The world's largest membrane bioreactor river water purification project is currently under construction at the Wenyu River Water Resources Project in Shunyi New City, Beijing (100,000 tons/day). Get applied. China has also developed a biodegradable bio-based superabsorbent resin based on agricultural product processing waste. This agricultural water-retaining agent product has been applied in Xinjiang, Guangdong, and Inner Mongolia.
