摘要： 国内首套400 kt/a煤基石脑油连续重整装置于2020年10月投料试车成功。工业应用结果表明:以低温煤焦油加氢生产的石脑油为原料,采用PS-Ⅵ催化剂,当平均反应器入口温度为481 ℃时,C+5产品辛烷值可达107,液体收率达到93.48%,芳烃产率和纯氢产率分别为82.21%和4.55%,产氢纯度高达97.95%,并且重整生成油中几乎检测不到烯烃,可避免微量烯烃带来的负面影响。由于第一反应器和第二反应器的温降较大,在工艺设计时建议适当减少第一反应器和第二反应器的催化剂装填量,以提高催化剂的利用率。该装置的开车成功,开辟了一条以煤炭为原料生产芳烃的新途径。

Abstract: China's first 0.4 MM TPY coal-based naphtha continuous catalytic reforming device was successfully put into commissioning in October 2020. Naphtha produced by hydrogenation of low temperature coal tar is used as feedstock with PS-Ⅵ catalyst. Industrial application results show that when the average reactor inlet temperature is 481 ℃, the octane number of C+5 product can reach 107, the liquid yield can reach 93.48%, the aromatics yield and pure hydrogen yield can reach 82.21% and 4.55% respectively, and the hydrogen purity can reach 97.95%. Moreover, olefins can hardly be detected in the reformate, which can avoid the negative effects of trace olefins. Due to the large temperature drop in the first and second reactors, it is suggested to reduce the amount of catalyst in the first and second reactors to improve the utilization rate of the catalyst. The successful operation of the unit opens up a new way to produce aromatics from coal.
