摘要: 以煤焦油加氢精制石脑油为原料,采用半再生重整催化剂进行催化重整制芳烃,考察了反应温度、压力、空速等条件对生成油液体收率和组成的影响。结果表明:反应温度升高,重整生成油液体收率降低,芳烃含量增加;压力增加,重整生成油液体收率降低,芳烃含量降低;空速对重整生成油的液体收率及芳烃含量影响较小。在优化条件下,环烷烃的转化率高达98.95%,重整生成油主要由芳烃、异构烷烃和正构烷烃组成,其中芳烃质量分数为84.87%,芳烃产率为71.79%。煤焦油加氢精制石脑油是生产芳烃的优质原料。

Abstract: Using hydrogenated coal-based naphtha as the feedstock and semi-regenerative reforming catalysts, the effects of reaction temperature, pressure, and space velocity on the liquid yield and composition of the product oil were investigated. The results showed that as the reaction temperature increased, the liquid yield of the reformed oil decreased, while the aromatic content increased. With pressure increasing, the liquid yield of the reformed oil decreased, and the aromatic content also decreased. Space velocity had a relatively minor impact on both the liquid yield and aromatic content of the reformed oil. Under optimized conditions, the conversion rate of naphthenes reached as high as 98.95%. The reformed oil mainly consisted of aromatics, iso-paraffins, and n-paraffins, with an aromatic content of 84.87% and an aromatic yield of 71.79%. Hydrogenated coal-based naphtha is a high-quality feedstock for the production of aromatics.
Key words: coal-based naphtha, semi-regenerative catalytic reforming, cycloparaffins, aromatics
