摘　　要：为了经济高效调整产品结构,降低炼油厂柴汽比,进行了催化裂化装置掺炼渣油加氢柴油的试验研究。结果表明,与重油催化裂化原料相比,渣油加氢柴油具有更好的可裂化性能和汽油选择性,其转化率高达79.46%,汽油收率高达62.72%。某装置掺炼5.34%渣油加氢柴油时,每天可减少柴油198.4 t,增产高辛烷值汽油154.1 t,可显著降低炼油厂柴汽比,汽油研究法辛烷值(RON)增加0.2个单位。In order to adjust the product structure economically and efficiently,experimental study on reducing diesel gasoline ratio by blending residue hydrotreater diesel into FCC feed was carried out.The results showed that,compared with the RFCC residue feed,the residue hydrotreater diestl has better cracking performance and gasoline selectivity.The conversion rate was as high as 79.46%,and the gasoline yield was up to 62.72%.When blended with 5.34%of residue hydrotreater diesel,diesel production could be reduced by 198.4 t d,and the high octane number gasoline production increased by 154.1 t d,resulting in a significant reduction of diesel gasoline ratio,meanwhile the octane number of gasoline increased by 0.2 unit.
