Title: Zhipeng Liu: Innovator in Catalytic Processes
Introduction
Zhipeng Liu is a prominent inventor based in Shandong, China. He has made significant contributions to the field of catalysis, particularly in the synthesis of polyether amines and diamino-dicyclohexyl methane. With a total of 2 patents, Liu's work showcases innovative methods that have the potential to impact various industrial applications.
Latest Patents
Liu's latest patents include a supported catalyst used for synthesizing polyether amine and a manufacturing method for this catalyst. The catalyst comprises a porous oxide as a support, with active components including Ni, Cu, Pd, and Rh. Additionally, it incorporates auxiliary agents such as Zr, Cr, Mo, Fe, and others. This catalyst is particularly effective in amination reactions for large molecular weight polyether polyols, demonstrating high activity and selectivity for low molecular weight polyether polyols. The manufacturing technique is noted for its simplicity and economic viability, indicating strong potential for future applications.
Another significant patent involves a method for preparing diamino-dicyclohexyl methane (HMDA) through the hydrogenation of diamino-diphenyl methane (MDA). The process begins with hydrogenating 4,4'-MDA to produce 4,4'-HMDA. When catalyst activity decreases, the feed is switched to a mixture of 2,4'-MDA and 4,4'-MDA, allowing for the stabilization of conversion before reverting to 4,4'-MDA. This method results in the production of 4,4'-HMDA with a trans-trans isomer content of 16-24 wt%, along with a mixture containing 2,4'-HMDA and 4,4'-HMDA.
