为了实现含油污泥的资源化、无害化处理，利用自制的Al-MCM-41催化剂对含油污泥进行催化热解处理，考察了温度、时间、氮气流量、污泥含水率等对油回收率的影响，并对热解产物进行了分析。结果表明，在催化剂质量分数为1.5%，氮气流量为100 mL/min，反应温度为430℃下处理3 h时，油回收率最高可达83.46%，与同等热解条件下未加催化剂相比，油回收率提高了4.02%，处理时间缩短了1 h以上，且催化热解大幅度提高了C₆-C₁₅的馏分收率；残渣热值在2 160 kJ/kg左右，可作为辅助燃料再利用。

In order to realize the resource utilization and harmless treatment of oily sludge,the self-made Al-MCM-41 catalyst is served in the pyrolysis treatment of oil sludge by means of a tubular reactor.The influences of pyrolysis temperature,reaction time,nitrogen gas flux,the water content in the oily sludge on the oil recovery rate and/or the conversion efficiency are investigated and the properties of pyrolysis products are analyzed.The highest oil recovery rate can reach 83.46% under the optimum pyrolysis parameters that catalyst dosage is 1.5%,nitrogen gas flux is 100 mL·min^-1,pyrolysis temperature is 430℃ and reaction lasts for 3 h.Compared with the same pyrolysis conditions without catalyst,the oil recovery rate increases 4.02 percentage points,the pyrolysis time shortens by 1 h,and the catalytic pyrolysis greatly improves the yield of C₆-C₁₅.In addition,the residue has a heat value of 2 160 kJ·kg^-1,and can be used as auxiliary fuel.
