摘要:
为解决中国石油兰州石化公司90万t/a柴油加氢改质装置开工后出现的原料与热量不足的问题，进行了掺炼催化柴油的工业试验。结果表明：当催化柴油掺炼比（质量分数）为10%，裂化反应器第1~第4床层温升依次为7，8，5，6 ℃时，航空煤油收率与柴油转化率最高。与掺炼前相比，掺炼10%催化柴油后，装置能耗由19.48 kg/t（以标准油计）提高至19.96 kg/t；产物中气相、轻重石脑油与航空煤油收率增加；精制柴油收率下降；重石脑油中环烷烃、芳烃质量分数分别提高了2.11，1.67个百分点；航空煤油冰点降低了10 ℃，烟点降低了8.2 mm；精制柴油的质量得到改善。
Abstract:
In order to solve the problems of insufficient raw material and heat in the 0.9 Mt/a diesel hydrogenation upgrading unit of Lanzhou Petrochemical Company， PetroChina， the industrial trial of blending catalytic diesel as feedstock was carried out. The results showed that when the catalytic diesel blending ratio was 10% and the temperature rise of the first to fourth beds in the cracking reactor was 7，8，5，6 ℃ respectively， the aviation kerosene yield and diesel conversion rate were the highest. Comparing with the scenario before blending， the energy consumption of the unit increased from 19.48 kg/t （based on standard oil） to 19.96 kg/t after blending catalytic diesel oil（10%）. The product yields of gas phase naphtha， light and heavy naphtha and aviation kerosene had increased， while the yield of refined diesel oil had decreased； the mass fractions of cycloalkanes and aromatics in heavy naphtha had increased by 2.11 and 1.67 percentage points respectively； the freezing point and smoke point of aviation kerosene had decreased by 10 ℃ and 8.2 mm respectively， and the quality of refined diesel oil was improved.
