摘要:
为了降低炼油厂柴油产量，多产高辛烷值汽油，采用中国石油石油化工研究院开发的多产高辛烷值汽油降低柴汽比的柴油催化转化工艺（DCP）技术，对中国石油玉门油田公司0.8 Mt/a重油催化裂化装置的两段提升管反应器进料喷嘴进行改造，将加氢改质柴油从第2提升管回炼油和油浆喷嘴下方的2个喷嘴接入反应器，并对改造后装置进行标定。结果表明：采用DCP工艺改造后，当装置掺炼加氢改质柴油质量分数依次为5.0%，7.5%，10.0%时，与空白标定相比，干气和焦炭收率分别减少0.40~0.51，0.16~1.23个百分点，汽油和液化气收率分别增加1.12~1.74，0.04~0.55个百分点，总液体收率增加0.71~1.58个百分点，装置柴汽比降低0.01~0.06个单位；催化稳定汽油烯烃体积分数降低0.60~1.95个百分点，异构烷烃体积分数增加1.11~2.29个百分点，研究法辛烷值（RON）提高0.3~0.7个单位；催化柴油中单环芳烃含量明显增加，但总芳烃含量变化不大；液化气组成基本保持不变，丙烯收率略有增加。
Abstract:
In order to reduce the production of diesel and increase the production of high octane gasoline in a refinery， the diesel catalytic conversion process （DCP） technology developed by Petrochemical Research Institute of PetroChina was adopted to reduce the ratio of diesel to gasoline. The feed nozzle of the two-stage riser reactor of the 0.8 Mt/a heavy oil catalytic cracking unit of Yumen Oilfield Company of PetroChina was modified. Hydrogenated modified diesel was connected from the two nozzles below the refining and slurry nozzles of the second riser into reactor，and the modified unit was calibrated. The results showed that after adopting the DCP process transformation， when the mass fractions of hydrogenated modified diesel blended in the unit were 5.0%， 7.5%， and 10.0% respectively， compared with the blank calibration， the yields of dry gas and coke decreased by 0.40-0.51 and 0.16-1.23 percentage points， and the yields of gasoline and liquefied gas increased by 1.12-1.74 and 0.04-0.55 percentage points， the total liquid yield increased by 0.71-1.58 percentage points， and the ratio of diesel to gasoline on the unit decreased by 0.01-0.06 units. The volume fraction of olefins in catalytic stabilized gasoline decreased by 0.60-1.95 percentage points， the volume fraction of isoparaffins increased by 1.11-2.29 percentage points， and the research octane number （RON） increased by 0.3-0.7 units. The content of monocyclic aromatic hydrocarbons in catalytic diesel increased significantly， but the total aromatic hydrocarbon content did not change significantly. The composition of liquefied gas remained basically unchanged， while the yield of propylene slightly increased.
