(57) Abstract: A chromium-free, copper-containing catalyst, Cu-Al-O, and a method for preparing the same are provided. The Cu-Al-O catalyst uses sodium carbonate (Na 2 CO 3 ) as a precipitant and co-precipitates copper nitrate (Cu (NO 3 ) 2 ) solution and sodium aluminate (Na 2 Al 2 O 4 ) solution. Prepared. The precipitate is filtered, washed to remove excess sodium and dried. The dried product to be used in the form of a powder, from about 700 ° C to 900 ° C The dry powder to be extruded or extruded should be from about 400 ° C The addition of various agents can promote hydrocracking. The Cu-Al-O catalyst can be employed in various applications in place of the Cu / Cr catalyst or the copper-based catalyst. |
