摘要

在能源转型背景下，利用煤焦油通过加氢裂化技术生产芳烃是实现“减油增化”的重要途径。本文采用多级孔Ni-Mo/Y催化剂，在固定床反应器中考察了温度、压力与空速对煤焦油加氢裂化产物分布及芳烃潜含量的影响，重点研究工艺参数对芳烃转化和单环烷烃保留之间的协同调控机制。结果表明，温度和空速具有关键调控作用，在366

C时、0.50 h

-1

时转化率与芳潜达最优平衡。温度过低或空速过高则多环芳烃转化不足，反之易导致单环环烷烃过度裂解；提高压力主要促进芳烃加氢并抑制裂解。在最优工艺参数（366

C， 15.0 MPa， 0.50 h

-1

）下，转化率、重石脑油产率及芳烃潜含量分别达到71.0 %、52.0 %和61.89 %。本文阐明了工艺参数在多级孔分子筛催化剂催化煤焦油制高芳潜石脑油中的作用机制，对推动煤焦油高值转化和芳烃生产多元化发展具有重要指导意义。

Abstract

Under the strategic background of low-carbon transformation of the energy structure

utilizing the rich aromatic hydrocarbon structure in coal tar and producing aromatics through hydrocracking technology is one of the key approaches to achieving the goal of "reducing oil and increasing chemicals". In this paper

using coal tar as the raw material and hierarchical pore Ni-Mo/Y catalyst

the effects of temperature

pressure and space velocity on the product distribution and aromatic hydrocarbon potential content of medium and low-temperature coal tar hydrocracking were investigated in a 100 mL fixed-bed reactor. We focused on the synergistic regulation of process parameters for aromatic hydrocracking and monocyclic alkane retention. Results show that reaction temperature and space velocity are key to controlling product selectivity. At 366

C and 0.50 h

-1

we achieved an optimal balance between conversion and aromatic potential. Lower temperatures or higher space velocity can prevent the full hydrogenation of polycyclic aromatic hydrocarbons. While the opposite conditions cause excessive cracking of monocyclic cycloalkanes and reduce aroma

tic potential. Additionally

higher reaction pressure mainly enhances aromatic hydrogenation and inhibits excessive cracking. Under optimal conditions (366

15.0 MPa

0.50 h

-1

)

coal tar conversion

heavy naphtha yield

and aromatic potential reached 71.0 %

52.0 %

and 61.89 %

respectively. This work clarifies the mechanism of action of process parameters in the process of multi-stage porous molecular sieve catalytic hydrocracking of coal tar to produce high-aromatic potential naphtha

which is of great guiding significance for promoting the high-value conversion of coal tar and the diversified development of aromatics production technology.
