Preparation of bimetallic catalysts for selective Ni Cu hydrogenation

摘要

A method for preparing a catalyst containing nickel and copper based bimetallic active phases and a support for a refractory oxide comprising the following steps: a) realizing the step of contacting the support with a solution containing a nickel precursor;(b) The step of contacting the carrier with the solution containing copper precursor is realized;(a) Steps (a) and (b) were carried out in unimportant order;The drying step of the catalyst precursor is realized after steps (a) and (b).Page: 11. The temperature is lower than 250 ℃;(d) Supplying the catalyst precursor obtained by step C;In a hydrogenation reactor, the reduction step is carried out in 5 minutes or less by contacting the precursor with the reducing gas at a temperature below 200 ℃.
