Preparation method of nickel copper bimetallic catalyst used for hydrogenation of aromatic compound

摘要

A method of preparing a catalyst comprising a bimetallic active phase comprising nickel and copper and a carrier containing a refractory oxide, and method of including the following process.The step of contacting the carrier with a solution containing a nickel precursorThe process of contacting the carrier with a solution containing a copper precursor- drying the catalyst precursor at temperatures below 250The resulting catalytic precursor is supplied to a hydrogenation reactor and the precursor is reduced to less than 200 degrees centigrade for less than 5 minutes in less than 200No selection
