摘　　要：以SZ渣油为原料,加入乙酸溶剂,研究了微波参数、蒸馏水、极性溶剂添加量及类型对微波改质效果的影响。结果表明,产品黏度和金属质量分数随辐射温度的升高,先降低后升高;产品黏度随辐射时间的延长,先降低后升高;硫质量分数随辐射时间的延长,先降低后趋于稳定。产品黏度、硫质量分数和金属质量分数随微波功率的增加,逐渐降低;随极性溶剂用量的增加,先降低后趋于稳定。与醇类极性溶剂相比,添加酸类极性溶剂微波改质效果更好,且升温速率更快。微波辐射过程中添加蒸馏水可以明显改善产品的性质。Using SZ residual oil as raw material and acetic acid as solvent, the effects of microwave parameters, distilled water,the amount and types of the polar solvents on the modification effects are studied. The resuhs show that the viscosity of the product and the metal content are firstly decreased then increased with the increase of irradiation temperature. By prolonging the irradiation time, the product viscosity exhibits the similar tendency but the sulfur content is firstly decreased and then tends to be stable. The product viscosity, sulfur and metal contents are decreased by increasing the microwave power but firstly decreased and then tends to be stable with the addition of polar solvent. Comparing with the alcohol polar solvent, better microwave modification effect and faster heating speed can be achieved by using acid polar solvent. The quality of the product could be obviously improved by adding distilled water.
