New method in catalyst development
Jun 26, 2017

1. chemical bond. This method is now widely used in the manufacture of polymerization catalysts. The aim is to make homogeneous catalysts solid. A carrier that can be chemically bonded to a transition metal complex. The surface has certain functional groups (or chemically treated), such as -X, -CH2X, and -OH groups. This kind of carrier and phosphine, arsine or amine, the phosphine, arsine or amination, then the surface electrons of phosphorus and arsenic or nitrogen atoms of ligand complex metal ions and transition metal complexes, prepared by solid catalyst chemical bonding, such as manufacturing, Ziegler Natta propylene bulk liquid phase polymerization catalyst carrier for the.

2. fibrosis. Manufacture of supported catalysts for noble metals. If borosilicate glass is made into glass fiber silk and corroded in concentrated hydrochloric acid solution, it is changed into porous glass fiber carrier and impregnated with platinum platinum acid solution to make it contain platinum component. According to the utility model, the fibrous catalyst is pressed into various shapes and the required degree of tightness, such as a catalyst for automobile exhaust oxidation, can be compressed into a short round tube. Carbon fibers are also available if they are not oxidation processes. The manufacturing process of fiber catalyst is complex and the cost is high.
