本文对综合利用炼厂气以扩大芳烃来源探索了一条新的途径。研究用氧化锑改性HZSM-5与沸石分子筛催化剂对炼厂气芳构化催化活性的影响,以及活化温度和反应温度对产物分布的效应,并对炼厂气(主要是C_4、烃类)在Sb/EIZSM-5沸石分子筛健化剂上芳构化过程作了初步探讨。实验结果表明,炼厂气可作为制备芳烃的原料。在活化反应温度500℃,空速为60ml/min,总芳烃平均收率为92%,C_6—C_8芳烃收率为77%,液态非芳烃含量为7.5%,
This article explores a new approach to the comprehensive utilization of refinery gas to expand the source of aromatics. The effects of antimony trioxide modified zeolite HZSM-5 and zeolite catalyst on the catalytic activity of refinery gas aromatization, as well as the effect of activation temperature and reaction temperature on the product distribution were studied. The effects of refinery gas (mainly C 4, hydrocarbons) The aromatization of Sb / EIZSM-5 zeolite molecular sieve was preliminarily discussed. Experimental results show that refinery gas can be used as a raw material for the preparation of aromatic hydrocarbons. The average yield of total aromatics was 92%, the yield of aromatics C_6-C_8 was 77%, the liquid non-aromatics content was 7.5% at an activation temperature of 500 ℃ and a space velocity of 60ml / min.
