摘　　要：随着焦化原料劣质化程度加深,研究重油反应规律以优化操作、增加液体收率受到了重视。利用重油热反应评价装置,考察不同反应深度下,汽油、柴油、蜡油、沥青质和甲苯不溶物含量的变化规律,系统归纳出了重油高反应深度条件下裂解缩合规律。研究表明,深度热反应条件下,原料油中沥青质充当反应中间产物,重蜡油组分开始发生二次裂解反应,且二次反应转化率与原料的残炭值存在线性关系。With the feedstock of delayed coker becoming increasingly inferior, more attention has been paid on the study of reaction rules of heavy oil to optimize the operation and increase the liquid yield. The change rules of gasoline, diesel oil, heavy gas oil, asphaltenes and toluene insoluble contents were investigated on a heavy oil thermal evaluation pilot plant under different reaction depths, and the cracking condensation laws of heavy oil under high reaction severity were summarized. The study shows that, under the thermal reaction conditions, the asphaltene in the feedstock is the intermediate reaction product. The heavy gas oil will undergo secondary cracking reaction, and the conversion rate of secondary reaction is in linear relation with carbon residue.
