查询词典 alumina cream

Catalysts are made by impregnating a porous transition alumina support with an aqueous solution of a copper ammine carbonate complex, draining off any excess of the impregnating solution, and then heating the impregnated support to a temperature above 80 DEG C to decompose the complex thereby depositing a basic copper carbonate compound on the surfaces of the pores of the transition alumina support.
