Abstract:

The 2.2 MM TPY FCC unit processing heavy oil of Russian crude oil of PetroChina Liaoyang Petrochemical Company adopts MIP-CGP technology(clean gasoline production technology for increasing propylene and producing more isomers) for renovation, using the dedicated catalyst CGP-LY. The calibration results show that under 100% production load conditions, compared with the FCC technology before the transformation, the yield of LPG remains basically unchanged after transformation by the MIP-CGP technology; the yield of propylene increases by 0.3 percentage points; the yield of gasoline increases by 5.47 percentage points, the RON is 92.23, with an increase of 1.18 units, the anti-knock property is improved, the olefin mass fraction decreases to below 30%, with a decrease of 16.78 percentage points, effectively reducing the oil pollution to the atmospheric environment; the coke yield increases by 3.73 percentage points; the conversion rate of feedstock has increased by 8.71 percentage points. This indicates that MIP-CGP technology has a good ability to reduce gasoline olefin content. While improving gasoline properties, it can significantly increase product yield, meeting the market demand for producing clean gasoline, reducing gasoline olefin content, increasing gasoline octane number, and increasing propylene yield.

摘要：

中国石油辽阳石化分公司2.2 Mt/a俄罗斯原油重油催化裂化装置采用MIP-CGP技术(增产丙烯、多产异构烷烃的清洁汽油生产技术)进行改造，使用专用催化剂CGP-LY。标定结果表明：在100%生产负荷条件下，与改造前的催化裂化技术相比，采用MIP-CGP技术改造后，液化石油气产率基本不变；丙烯产率提高了0.3百分点；汽油产率提高了5.47百分点，研究法辛烷值为92.23,提高了1.18单位，抗爆性提高，烯烃质量分数降至30%以下，降低了16.78百分点，有效减少了油品对大气环境的污染；焦炭产率提高了3.73百分点；原料油转化率提高了8.71百分点。上述结果说明MIP-CGP技术具有良好的降低汽油烯烃含量的能力，在改善汽油性质的同时，能显著提高产品产率，满足生产清洁型汽油、降低汽油烯烃含量、提高汽油辛烷值、提高丙烯产率的市场需求。
