Zeolite molecular sieve CH4/N2 separation adsorbent developed by Chinese molecular sieve manufacturer wins award Hay:F07LYJL

The 2021 China Petroleum and Chemical Technology Innovation Conference was recently held in Wuhan. China's leading molecular sieve manufacturer LYJL Molecular Sieve Technology Corporation and TY University of Technology and other units jointly completed the "Zeolite Molecular Sieve CH4/N2 Separation Adsorbent Creation and Low-Concentration Coalbed Methane Enrichment" The "Complete Technology" project won the first prize of China Petroleum and Chemical Industry Federation's 2021 Technology Invention Award.


"This year's award-winning projects are of high overall level and strong innovation. In particular, the projects that have won the special and first prizes for technological invention and technological progress have all ranked among the world's advanced technologies of the same kind, and some technologies are at the world's leading level." China Petroleum and Chemical Corporation Li Shousheng, president of the Confederation of Industry, said at the meeting that today's world is undergoing profound changes unseen in a century, and technological innovation is one of the key variables.

This award has played a positive role in the promotion and market application of "the creation of zeolite molecular sieve CH4/N2 separation adsorbent and integrated technology for low-concentration coalbed methane enrichment". It is reported that the project takes the enrichment and concentration of methane in low-concentration coalbed methane as the research background, and conducts research on high-efficiency enrichment technology for the core technical issues in the comprehensive development and utilization of coalbed methane. The coalbed methane with methane content of 5-50% is recycled and utilized As the goal, the use of pressure swing adsorption separation technology, with the separation adsorbent as the core, selects the high-selectivity CH/N separation zeolite molecular sieve adsorbent, and carries out the synthesis optimization of the adsorbent and the development of the matching pressure swing adsorption separation process.


Natural gas is the most realistic low-carbon and clean energy at present, but China's conventional natural gas production capacity is insufficient and needs to be supplemented by the development of unconventional natural gas, especially shale gas and coalbed methane. Methane, as the second largest greenhouse gas, has a greenhouse effect 20-25 times that of carbon dioxide. The effective implementation of the above projects will help to achieve the goal of carbon neutrality.
