Preparation method of catalyst - leaching method
Jun 26, 2017

A porous catalyst is prepared from a multi component system by pumping some of the material with an appropriate liquid agent (or water). For example, the manufacture of Raney nickel catalyst, the nickel and aluminum melting furnace in quantitative, melt cooling become alloy. The alloy is broken into small particles, using sodium hydroxide aqueous solution soaking, most of aluminum was dissolution (the production of sodium aluminate is formed with high activity), porous nickel.
