Recently, Sinopec's Southwest Chemical Research and Design Institute Co., Ltd. (Hereinafter referred to as "Southwest Institute") provided the core catalyst for the largest single-series natural gas hydrogen production plant in China, Zhejiang Petrochemical 100000 m3/H natural gas hydrogen production plant, which was successfully put into operation.
It is reported that the unit adopts the process technology of pre-conversion + one-stage conversion, in which the pre-conversion reactor is filled with a new generation of CN-14R pre-conversion catalyst provided by Southwest Institute, which has stable structure, strong carbon deposition resistance and is a pre-reduction catalyst. After the catalyst is adopted, the cold state start-up time of the device is less than 10 hours, the reaction reaches the process design requirement in less than half an hour after feeding, the methane content of the outlet process gas is reduced to 73%, and the high hydrocarbon above C2 is less than 0.1%, so that the start-up time of the device is greatly shortened, and a large amount of start-up cost is saved for owners. With more than 60 years of professional catalyst research, production and application experience,
Southwest Institute is the earliest research Institute in China to carry out low-pressure methanol synthesis process and catalyst research. The research of this technology has successfully broken the monopoly of foreign companies in low-pressure methanol synthesis technology, and has won many national and provincial awards. In 1996, it was listed as a key promotion project of national scientific and technological achievements by the Ministry of Science and Technology. Southwest Institute is mainly engaged in technical research and development, product production and supply, engineering design, project management and project EPC of gas adsorption and separation (PSA), natural gas chemical industry, coal chemical industry, C1 chemistry, hydrogen energy, carbon capture, nickel/copper/precious metals and other series of catalysts, with profound technical precipitation, complete design qualification and rich engineering experience. To provide users with perfect technical solutions.
Southwest Institute, as the "National Research and Promotion Center of Pressure Swing Adsorption Gas Separation Technology", is the technological pioneer and leader in the field of gas separation, has the "State Key Laboratory of Industrial Emission Gas", has strong R & D strength, comprehensive technical reserves, and leads the development direction of adsorption separation technology. It provides technical support and guarantee for the development of refining, metallurgy, hydrogen energy, carbon recovery and carbon emission reduction industries. It has more than 20 patented technologies related to fuel cell hydrogen, and the technology of preparing hydrogen for fuel cell vehicles from industrial by-product gas has won the first prize of Sinochem Science and Technology Progress in China.
As early as 2004, the pre-conversion catalyst of Southwest Institute was applied in industry for the first time. After intensive research by the R & D personnel of the catalyst, similar products at home and abroad were continuously upgraded and improved, and it was successfully applied in the 100000 m3/H natural gas hydrogen production plant of Zhejiang Petrochemical Company. The successful start-up of
the unit marks the successful operation of the hydrocarbon conversion catalyst in the large-scale refining and chemical unit of the Southwest Institute, and further consolidates the leading position of the nickel conversion catalyst in the industry in China.
