摘要

以阿曼减渣为原料,对其丙烷脱沥青工艺的溶剂组成和操作条件进行优化,对制备的30#硬质沥青的混合料性能进行考察,并采用固定床催化裂化装置对重脱沥青油的催化裂化性能进行研究。实验结果表明,丙烷脱沥青工艺的最佳条件为:混合溶剂(20%(w)异丁烷、80%(w)丙烷),抽提塔塔顶温度68℃,沉降塔塔顶温度81℃,溶剂体积比5.0,抽提压力4.35MPa;在此条件下,轻脱沥青油收率为25.1%,其性质满足光亮油料指标要求;脱油沥青收率为46.0%,软化点61.7℃,采用沙中减渣为调和软组分可制备出合格的AH-30硬质沥青,30#沥青混合料具有良好的车辙动稳定度和浸水残留稳定度;重脱沥青油可作为重油催化裂化原料,轻油收率(汽油+柴油)为61.70%。
        The solvent composition and operating conditions of propane solvent deasphalting of Oman vacuum residue were optimized,and the mixture performance of blended 30# asphalt was investigated;meanwhile,the catalytic cracking performance of heavy deasphalted oil was studied in fixed bed catalytic cracking unit. The result showed that the optimal conditions were as follows:mixture solvent of 80%(w) propane and 20%(w) iso-butane,extraction tower top temperature of 68 ℃,settling tower top temperature of 81 ℃,volume ratio of solvent to vacuum residue of 5.0,extraction pressure of 4.35 MPa;Under this condition,the yield of light deasphalted oil was 25.1% and the properties of light deasphalted oilconformed to the requirement of bright stock;the yield of de-oil asphalt was 46.0% and the softening point of de-oil asphalt was 61.7 ℃;meanwhile,de-oil asphalt could be used to produce 30# asphalt by blending with Saudi Arab Middle vacuum residue,and the blended 30# asphalt mixture had high rut dynamic stability and water resistant stability. Heavy deasphalted oil could be used as feedstock of catalytic cracking and light yield oil(gasoline and diesel) was 61.70%.
