Carbon dual hydrogenation catalyst industrial application soon

The national "863" key project - a breakthrough in the research of highly dispersed precious metal catalytic materials and applications in important chemical processes, and the engineering application research project of the highly dispersed palladium catalyst undertaken by the China Petroleum and Petrochemical Research Institute in the carbon selective hydrogenation process passed last week The Ministry of Science and Technology organized an on-site inspection. Researchers have tackled the key aspects of the carbon 2 hydrogenation process and prepared new catalysts that are highly active and highly selective. This result will effectively increase ethylene production and resin quality. The 12-ton new carbon-dihydrogenation catalyst produced by the Lanzhou Chemical Research Center will be used for industrial applications at the 240,000 tpa ethylene plant of Lanzhou Petrochemical Company at the end of this month or early next month.

Researchers at the PetroChina Research Institute of Petroleum and Petrochemicals have made strenuous efforts to successfully synthesize layered inorganic precursors and successfully prepared novel highly dispersed carbon dual hydrogenation catalysts, which have successfully completed the 100 kilograms of new carbon dual hydrogenation catalysts. Scale-up preparation and 1000-hour engineering assessment. After the evaluation of the industrial sideline, the new catalyst activity can be increased by 10%, and the selectivity can be increased by more than 20%. The increase in ethylene can be greatly increased, and a single set of equipment can increase the production of ethylene by thousands of tons per year, and the efficiency of the company exceeds 6 million yuan. The catalyst can also effectively increase the purity of the ethylene product and comprehensively improve the quality of the resin product. The current preparatory work for the new carbon dihydrogenation catalyst for the industrial application of Lanzhou Petrochemical has been completed. The project team has applied for 6 invention patents.

Industry experts believe that high-dispersion-supported noble metal catalysts and their applications have broken through the uniform dispersion and stabilization of active components on the surface of carriers, built a high-dispersion-supported catalyst to prepare key engineering technology platforms, and built highly dispersed supported catalysts. The preparation of the demonstration device has formed an application system for highly dispersed supported catalysts in important petrochemical processes, which has greatly promoted the industrialization of high performance catalysts in China's ethylene industry.

The ethylene industry is the leader and foundation of the petrochemical industry. The purity of ethylene products directly determines the quality and performance of subsequent products. According to the person in charge of Lanzhou Chemical Research Center, carbon dihydrogenation is the selective hydrogenation of acetylene in ethylene products to ethylene, which is one of the key technologies for the preparation of polymer grade ethylene. Therefore, carbon dihydrogenation plays an important role in the petrochemical industry. The role.
