摘要:
在中国石油宁夏石化公司260万t/a重油催化裂化装置中,以常压渣油与回炼催化裂化柴油为原料,采用MLC-500 NH型高活性降烯烃催化剂,生产出低烯烃高辛烷值汽油。结果表明:催化裂化柴油回炼后,产物中轻柴油和液化气收率分别降低了2.04,0.15个百分点,汽油、干气收率和转化率依次提高了1.32,0.11,1.29个百分点;汽油烯烃体积分数降低,芳烃体积分数增加,研究法辛烷值提高了0.3个单位;催化剂单耗由回炼前的1.00 kg/t降至回炼后的0.94 kg/t。
Abstract:
In the 2.6 Mt/a heavy oil fluid catalytic cracking(FCC) unit of Ningxia Petrochemical Company,PetroChina, the high octane gasoline with low olefin content was produced with the atmospheric residual oil and FCC diesel oil as raw materials and MLC-500 NH as high activity olefins reducing catalyst. The results showed that after FCC diesel was reprocessed,the yields of light diesel oil and liquefied gas decreased by 2.04 and 0.15 percentage points respectively,the yields of gasoline,dry gas and the conversion rate increased by 1.32,0.11 and 1.29 percentage points respectively. The volume fraction of olefins in gasoline decreased,while the volume fraction of aromatics increased,and the research octane number of gasoline increased by 0.3 unit. The catalyst consumption decreased from 1.00 kg/t before reprocessing to 0.94 kg/t after reprocessing.
