Beschreibung
Zusammenfassung:The invention provides an extrusion molding method of an acetophenone hydrogenation catalyst, which is characterized by comprising the following steps: kneading catalyst raw powder, silica sol, deionized water, an extrusion aid and a pore-enlarging agent into a plastomer according to a certain proportion, and then carrying out extrusion, drying and roasting to prepare a strip-shaped catalyst. The pore channel structure of the catalyst can be obviously improved by adding the pore-enlarging agent, phenethyl alcohol generated by acetophenone hydrogenation can be quickly diffused out of the pore channel of the catalyst, the retention time of phenethyl alcohol on the surface of the catalyst is shortened, and the generation of a byproduct ethylbenzene is effectively reduced; meanwhile, heat released by catalytic hydrogenation can be rapidly removed, agglomeration of the copper nanoparticles is effectively avoided, and the service life of the catalyst is prolonged. 本发明提供一种苯乙酮加氢催化剂的挤条成型方法,其特征是将催化剂原粉,硅溶胶,去离子水,助挤剂和扩孔剂以
