Trans-1,4-cyclohexanedicarboxylic acid catalyst and preparation method

The present invention relates to the production method of preparing trans-1,4-cyclohexanedicarboxylic acid catalyst, 1,4-cyclohexanedicarboxylic acid synthesis in the application of the resulting catalyst, and the catalyst in trans, mainly hydrogenation catalyst solution of terephthalic acid 1,4-cyclohexanedicarboxylic acid in the trans-1,4-cyclohexane dicarboxylic acid is not high selectivity of the prior art exists. By using the present invention is a process for preparing trans-1,4-cyclohexanedicarboxylic acid catalyst, comprising: a compound containing Mo and alumina impregnated with a solution containing compound W, dried and calcined to prepare precursor I; with H2 and alkanes mixed gas precursor process I, to obtain a composite carrier; and a compound containing Pd supported Pt-containing compound; a compound of Pt and Pd is reduced to a metal catalyst to obtain the technical solution solves this problem, it can be used industrial production of trans-1,4-cyclohexane dicarboxylic acid.
