Assignee: NINGBO UNIVERSITY OF TECHNOLOGY
Field: Chemical engineering (Chemistry)
Classification: CPC B  C | IPC B  C

Claim 0:
1. A catalytic hydrogenation method for carbon nine resin, wherein the method comprises the following steps:
1) Preparing a carbon nine resin stream;
2) Pretreating the carbon nine resin stream, thereby producing a pretreated carbon nine resin;
3) Adding a Pt—W—Y/γ-Al2O3 catalyst in the first half of a fixed bed, adding a Pd—Zr—Nd/γ-Al2O3 catalyst in the second half of the fixed bed, and feeding hydrogen for reduction of the Pt—W—Y/γ-Al2O3 catalyst and the Pd—Zr—Nd/γ-Al2O3 catalysts; and
4) catalytic hydrogenating under catalytic hydrogenation conditions the pretreated carbon nine resin in the fixed bed.
