Latest Patents

Jin is associated with 1 patent: “Method for Preparing Polyether Amine Catalyst, and Polyether Amine.” The invention describes a supported-metal catalyst using γ-alumina as a carrier and basic copper, nickel, and cobalt carbonates as metal precursors. The catalyst is prepared through equivalent-volume impregnation, two adsorption-and-roasting stages, and a reduction stage.

Using basic carbonates allows the precursors to decompose more readily, producing water and carbon dioxide and potentially reducing waste-gas treatment processes and costs. The patent also describes using the catalyst to improve conversion and primary-amine selectivity while reducing product color, which may yield polyether amine with greater activity and broader potential applications.
