多级孔Hβ分子筛NiWP催化剂的制备与加氢脱芳性能
Preperation and Hydrodearomatization Performance of NiWP Catalyst Containing Hierarchical Hβ
摘要
Abstract
The hierarchically mesoporous Hβzeolite was synthesized by alkali treatment to commercial Hβzeolite in NaOH solution.The composite carrier was prepared by mixing the hierarchical Hβ zeolite and Al2 O 3 .The hierarchical NiWP/Hβ-Al2 O 3 catalysts were prepared by incipient wetness impregnation method,and characterized by means of XRD,BET and TEM. The hydrodearomatization of the prepared NiWP/Hβ-Al2 O 3 catalyst was evaluated in a miniature fixed bed reactor with fluid catalytic cracking diesel as raw material.The results suggested that the prepared NiWP/Hβ-Al2 O 3 catalyst has an excellent hydrodearomatization activity,and under the condition of the reaction temperature 360 ℃,reaction pressure 8.0 MPa, hydrogen to oil volumetric ratio 800 and liquid hourly space velocity 1.0 h-1 ,the cetane number was increased from 7.21of feed to 46.96 of product.关键词
