摘　　要：以高选择性、低能耗地将劣质重质原料转化为优质清洁油品和化工原料为目标,中石化石油化工科学研究院有限公司开发了高选择性催化裂化(RTC-G)技术,并在中国石化济南分公司进行了首次工业应用。与空白标定相比,在相同转化率下,液化气收率增加1.96百分点,汽油收率降低0.51百分点,干气产率和焦炭产率分别降低0.49百分点和0.80百分点,油浆产率降低2.18百分点,产品分布明显改善;适当提高转化率,液化气收率基本不变,汽油收率增加3.73百分点,油浆产率降低3.21百分点,焦炭选择性降低0.78百分点。使用RTC-G技术后,高价值产品选择性提高,产品结构进一步改善。RTC-G技术成为“双碳”目标背景下企业降碳增效的有效手段。In order to convert low-quality heavy raw materials into high-quality clean oil products and chemicals with high selectivity and low energy consumption,the highly selective catalytic cracking(RTC-G)technology was developed by SINOPEC Research Institute of Petroleum Processing Co.,Ltd.and applied in SINOPEC Jinan Company for the first time.Compared with blank calibration,under the same conversion rate,the yield of LPG increased by 1.96 percentage points,the yield of gasoline decreased by 0.51 percentage point,the yields of dry gas and coke reduced by 0.49 percentage point and 0.80 percentage point,respectively,the yield of slurry decreased by 2.18 percentage points,and the product distribution was significantly improved.By appropriately increasing the conversion rate,the yield of liquefied gas was basically unchanged,the yield of gasoline increased by 3.73 percentage points,the yield of slurry decreased by 3.21 percentage points,and the selectivity of coke decreased by 0.78 percentage point.After using RTC-G technology,the selectivity of high-value products was improved,and the product structure was further improved.RTC-G technology has become an effective means for enterprises to reduce carbon emission and to increase benefits under the background of“Double Carbon”target.
