【Frontiers in HaiChuan Chemical Technology】Complete regeneration of the catalyst more than 100 times in a chlorine-free oxidation atmosphere achieved for the first time

Thread Content

On April 10, the Shanghai Research Institute of Petrochemical Technology, in collaboration with Fuzhou University, the Shanghai Institute of Advanced Study of the Chinese Academy of Sciences, and other institutions, published an academic paper in the journal Science under the category of \"First Release\" to present the results of their collaborative efforts in developing new propane dehydrogenation catalysts. Researchers from the Shanghai Institute are co-first authors of the paper. Sinopec Supercomputing Center (Nanjing) provides computational resource support. In recent years, the shale gas revolution and the \"dual carbon\" strategy have driven rapid development of propane dehydrogenation technology, making it the mainstream method for the targeted production of propylene. Developing green, halogen-free recycled propane dehydrogenation catalysts has always been a major cutting-edge challenge in this field. Based on these findings, a research team comprising Fuzhou University and the Shanghai Institute successfully developed a highly durable, self-regenerating supported Pt/Ge-MFI molecular sieve propane dehydrogenation catalyst, and for the first time achieved over 100 complete regenerations of the catalyst in a chlorine-free oxidative atmosphere. Since 2007, with the continuous support of the Technology Department of the group company, the Shanghai Institute has established a simulation computing research team to carry out fundamental research in computational catalysis and molecular simulation. In the results of this collaborative research, the team from the Shanghai Institute employed a variety of research methods, providing new ideas and theoretical support for the development of novel platinum-based catalysts for alkane dehydrogenation.
