对利用乳化重油作为催化裂化原料进行了探讨 ,认为重油经乳化后减小了原料雾化后油滴直径 ,改善了催化剂与原料的接触环境和产品分布 ,在乳化剂用量 3 0 0 0 μg/g,掺水量 4%左右时 ,可以提高轻油收率 1 .80个百分点 ,干气和焦炭产率分别下降 0 .3 3和 0 .3 5个百分点 ,产品性质基本不变 The use of emulsified heavy oil as a raw material for catalytic cracking was discussed, the heavy oil emulsified to reduce the diameter of the droplet after atomization of raw materials to improve the contact environment of the catalyst and the raw materials and product distribution in the emulsifier dosage of 30 000 μg / g, when the water content is about 4%, the yield of light oil can be increased by 1.80%, the dry gas and coke yield decrease by 0.333 and 0.35% respectively, the nature of the product is basically unchanged
