    Recently, researchers from the National Key Laboratory of Structural Chemistry of Fujian Institute of Chinese Academy of Sciences made new progress in the research of coal-based dmoethyl carbonate catalysts, and successfully developed atomic-grade dispersed Pd catalysts with excellent catalytic properties. The study will accelerate the industrialization of coal-based methamphetylate catalysis technology.
    atomic-grade dispersed Pd catalysts show good catalytic properties: CO conversion rate of more than 80%, carbonate selectivity close to 100%, continuous operation of 100 hours without attenuation .
    based on the experimental results, the researchers revealed the catalytic functional sub-components of selective regulation of products: the single Pd activity center of atomic dispersion is conducive to the production of carbonate, while the dual-Pd activity center is conducive to the generation of another product of oxalate. They then obtained a stable atomic-level dispersed Pd catalyst with molecular sieve through theoretical calculation optimization, rational design and controlled synthesis, which is consistent with the structure of the theoretical design catalyst model.
    is known as a green chemical, and its demand is growing rapidly with the rapid development of the power battery and polycarbonate industry. At present, the industry mainstream ester exchange production technology has high product cost, raw material epoxy propane production process pollution is serious and so on.
    Institute of Material Structure of the Chinese Academy of Sciences has developed coal-based glycol technology after more than 30 years of basic research and applied research. On the basis of coal-based ethylene glycol technology, the researchers developed coal-based carbon-carbon-carbon-methylene catalytic technology through technological expansion. Compared with the ester exchange method, the raw materials of coal-based methamphetrate are only methanol, CO and O2, and the product cost is low, which has a strong competitive advantage. However, due to the low comprehensive performance of catalyst activity, selectivity and stability, coal-based paracamite catalysis technology has not been able to achieve industrialization.
