Abstract
The invention provides an efficient catalyst for cashew nut shell oil hydro-conversion and a preparation method thereof. The catalyst comprises a hydrogenation active component Pt, a catalyst carrier EU-1 type zeolite molecular sieve and a catalyst modifier MO2 (M is Zr < 4 + >, Ti < 4 + > or Ce < 4 + >). The preparation method comprises the following steps: jointly impregnating a hydrogenation active component Pt, a modifier MO2 and an EU-1 zeolite molecular sieve, drying to obtain a catalyst precursor, and roasting the obtained precursor to obtain the PtO2-MO2 / EU-1 catalyst. Through the synergistic interaction between the unique pore structure of the EU-1 type zeolite molecular sieve and different metals, the catalyst provided by the invention realizes efficient hydro-conversion of cashew nut shell oil, and has a long service life.
