摘要
利用真空管式热解炉对延长油田含油污泥进行真空热解,研究了热解终温、保温时间、升温速率、催化剂种类及其加量对油回收率的影响;将热解残渣与标准煤粉制成粉末状燃料,测定了燃料热值,分析了燃烧烟气中各项污染物浓度。研究结果表明:热解终温与保温时间对油回收率有很大影响。在各催化剂中,活性白土的催化效果最好,其加量为1%时,油回收率可达83%。粉末状燃料的热值达到24 000 k J/kg,超过烟煤的热值。燃料燃烧烟气中的各项污染物浓度均低于GB 13271—2014《锅炉大气污染物排放标准》规定的限值,可将其作为燃煤锅炉的燃料使用。真空热解是含油污泥资源化利用的切实可行的方法之一。
The paper studied vacuum pyrolysis of oil sludge from Yanchang oilfield and investigated the influence of pyrolysis temperature,time,temperature raising rate,categories and amount of catalysts on oil recovery yield. Powdered fuel was prepared from pyrolysis residue and the heating value was measured. The pollutants in the smoke were analyzed. Results showed that pyrolysis temperature and time had a great effect on oil recovery yield. Activated clay was found to be the best catalyst for pyrolysis and the oil recovery yield achieved 83% when catalyst dosage was 1%. The heating value of the powdered fuel was24 000 k J / kg,exceeding that of soft coal. The concentration of pollutants in the smoke were far below the Emission Standard of Air Pollutants for Boiler（ GB 13271—2014）. Vacuum pyrolysis was an effective resource recovery way for oil sludge.
