【摘要】 为满足乙烯市场对优质乙烯原料的需求，中石化石油化工科学研究院有限公司开发了直馏柴油加氢改质生产优质乙烯原料(MHUG-E)技术第二代专用加氢改质催化剂RIC-33和RIC-31。与上一代催化剂RHC-131相比，RIC-33和RIC-31催化剂活性更适合加工直馏柴油，同时反应所得的未转化柴油具有更高的链烷烃含量，未转化柴油和轻石脑油馏分均可作为优质乙烯原料。研究结果表明，催化剂RIC-33和RIC-31的原料适应性好、活性适中、稳定性高，同时其再生催化剂具有与新鲜剂相当的活性和链烷烃选择性。更多还原

【Abstract】 To meet the demand for high-quality ethylene raw in the ethylene market, SINOPEC Research Institute of Petroleum Processing Co.,Ltd. has developed second-generation MHUG-E dedicated hydroupgrading catalysts RIC-33 and RIC-31. Compared with the previous generation catalyst RHC-131, RIC-33 and RIC-31 catalysts are more suitable for processing straight-run diesel, and the unconverted diesel obtained from the reaction has a higher content of paraffin. Both unconverted diesel and light naphtha fractions can be used as high-quality ethylene raw. The experimental results of raw material adaptability, catalyst stability and regenerability show that the RIC-33 and RIC-31 have good adaptability to raw materials, high catalyst activity and stability. The regenerated catalysts have similar activity and paraffin-selectivity comparable to the new catalysts.更多还原
