以地沟油和龙口页岩油为原料,考察了不同配比的页岩油与地沟油共催化裂化及其产物分布规律。结果表明,地沟油质量分数为25%时,轻油收率和液收率最高,分别为54.24%和78.13%,转化率达到92.23%。对汽油馏分和柴油馏分组成进行分析可知,随着地沟油质量分数的逐渐增加,汽油中的芳烃质量分数先减少后增加,杂原子化合物的质量分数先减少后增加;当地沟油质量分数为25%时,汽油馏分中的芳香烃质量分数在50%左右。裂解气中主要是C₃及以下气体,质量分数达到65%以上。

Using waste cooking oil and Longkou shale oil as raw materials,the co-catalytic cracking of shale oil and waste cooking oil under different ratios and the products distribution are studied.The results show when the mass fraction of waste cooking oil in feedstock oil is 25%,the yields of light oil and liquid reach the highest,54.24% and 78.13%,respectively,and the conversion rate is 92.23%.The analysis shows that with the gradual increase of the mass fraction of waste cooking oil,the mass fractions of both aromatics and heteroatomic compounds in gasoline firstly decreases and then increases.The mass fraction of aromatic hydrocarbons in gasoline fraction is only about 50% when the mass fraction of waste cooking oil in feedstock oil is 25%.The cracked gas contains mainly C₃ and lighter hydrocarbons,with a mass fraction more than 65%.
