SELECTIVE HYDROGENATION CATALYST FOR PRODUCING BIODIESEL AND PREPARATION METHOD AND APPLICATION THEREFOR

WIPO Patent Application WO/2017/185928

A1

A selective hydrogenation catalyst for producing biodiesel and a preparation method and an application therefor. The selective hydrogenation catalyst comprises a carrier and a main metal active component, the main metal active component being loaded onto the carrier; the weight percentage of the catalyst product occupied by the main metal active component is 5-30%, the main metal active component being one or a combination of more than one oxide containing Co, Mo, Ni, or W, and the carrier being composed of 1-8% molecular sieves, 25-65% amorphous silicon aluminium, 30-65% aluminium oxide, and 2-10% graphene adjuvant calculated by weight percentage of the raw ingredient. The method for preparing the catalyst comprises immersing the carrier in a metal salt solution containing Co, Mo, Ni, and/or W for 4-20 h to obtain an immersed carrier; and, after freeze-drying, calcining the immersed carrier to obtain the selective hydrogenation catalyst. Under the same load, the carrier has a larger active surface area and has more active sites, reducing reaction temperature and improving hydrogenation performance.
