HYDROGENATION CATALYST USING MULTIPLE IMPREGNATIONS OF AN ACTIVE METAL SOLUTION |
摘要 |
A process for producing a catalyst that results in improved yields and productivity to ethanol. The process involves the steps of preparing a solution comprising one or more precursors to an active metal and impregnating a first portion of the solution on a support to form a first impregnated support. The first impregnated support is calcined to form a first calcined support and a second portion of the solution is impregnated on the first calcined support. The catalyst is useful for hydrogenating alkanoic acids to ethanol. |
