摘　　要：降低催化裂化汽油硫含量助剂LDS-Ll在荆门分公司Ⅱ套重油催化裂化装置的应用结果表明:在装置操作条件基本稳定的情况下,催化剂上降硫有效组分含量为2000μ/g时,可使汽油硫含量由加剂前的0.09％,降低到加剂后的0.07％左右,脱硫率在20％以上,轻液体收率提高了0.9个百分点,且该剂对产品其它性质无不良影响。Commercial application result of IDS-L1 desulfurization assistant in the second RFCC unit of Jingmen Company shows that under the stable operation conditions, when concentration of LDS-L1 desulfurization assistant deposited on FCC catalyst reaches up to 2000μg/g, sulfur content of FCC gasoline can be reduced from 0.09% to 0.07% and the desulfurization rate is over 20% . In addition, total yield of LPG, gasoline and LCO has been increased by 0.9 percent point without negative influence on other properties of the product.
