    Recently, Sinopec has made new progress in the field of biodegradable materials
    .
    The 60,000-ton/year PBST production device process package jointly developed by the Beijing Research Institute of Chemical Industry and the China Textile Research Institute passed the review of the Science and Technology Department of the Group Corporation on May 18, and the engineering design of the industrial production device will be carried out accordingly
    .
    The "maleic anhydride hydrogenation catalyst and 20,000 tons/year maleic anhydride hydrogenation to succinic acid complete technical process package" for the supply of key raw materials of PBST also passed the review of the Science and Technology Department of the group company on May 19, which can be regarded as China's biochemical industry.
    The large-scale development of degradable polyester materials provides key technical support
    .
    ? With the advent of 2021, the most stringent plastic restriction order in history has entered the implementation stage, and the degradable plastics industry may usher in new opportunities for rapid development
    .
    PBST is a biodegradable polyester independently developed by the Beijing Institute of Chemical Technology.
    It has good thermal stability, mechanical properties and biodegradability, and its comprehensive performance is better than similar products at home and abroad.
    It can be widely used in disposable packaging, plastic bags, agricultural Film and other fields
    .
    ? At present, Sinopec is actively planning the development of PBST industrialization, and is striving to build a new industrial chain of Sinopec's biodegradable materials
    .
    The "60 thousand tons/year PBST production device process package" jointly developed by Beijing Institute of Chemical Technology and China Textile Institute based on their respective business advantages has high process reaction efficiency, few side reactions, excellent product quality and low energy consumption
    .
    The project has developed a variety of products such as biodegradable film bag materials, injection molding materials, fiber materials, and foam materials to support the promotion and application of biodegradable materials
    .
    ? With the increase in the scale of the biodegradable material industry, problems such as insufficient capacity and high prices in the market for succinic acid, a key raw material for the production of PBST, have become increasingly prominent, which severely restricts the industrial development of PBST
    .
    In order to solve this dilemma, Beihua Institute quickly established a joint research team based on the olefin selective hydrogenation technology platform, and launched the "20 thousand tons/year maleic anhydride hydrogenation to succinic acid complete technology package development" institute on January 13 this year.
    Level key core technology research project, with the chief expert of the group company Wang Guoqing as the project leader, leading the scientific research team to tackle key problems in the preparation and separation of the key monomer succinic acid in the industrialization of PBST
    .
    ? The scientific research team overcomes difficulties such as tight project time and heavy tasks, and carried out tests and development work day and night, and successively completed catalyst optimization and finalization, analysis of impurity components, polymerization test of small test samples, and hydrogenation of 20,000 tons/year of maleic anhydride Development of a complete set of technology and process package for succinic acid production
    .
    ? The maleic anhydride hydrogenation catalyst developed by the project has high low-temperature activity and good stability, which is beneficial to improve the selectivity of succinic anhydride
    .
    Based on this, the complete set of technical process design and equipment selection are reasonable, the reaction conditions are mild, the product yield is high, and the three wastes discharge meet the environmental protection requirements
    .
    The purity of the succinic acid product produced by this technology is over 99.
    5%, which meets the requirements of PBST production, and the PBST sample produced has good color and high molecular weight
    .
    The technology has independent intellectual property rights and has applied for 13 Chinese invention patents.
    Based on this, engineering design can be carried out to realize the industrialized production of succinic acid and effectively solve the key raw material supply problem that restricts the development of PBST's industrialization
    .
    ? So far, PBST has formed a complete technology research and development chain and value chain from raw materials, polymerization technology, material processing and application technology to analysis and characterization of PBST, providing strong technical support for Sinopec's construction of a "one base, two wings, three new" industrial structure
