污泥低温催化热解是一项具有污泥处理与能源回收双重性质的资源化技术。本文采用低温热解技术处理城市污水污泥,比较了在有/无催化剂条件下,停留时间和反应温度对热解产物产率及特性的影响。结果表明,催化剂的使用提高了污泥热解油的产率和品质,降低了产炭率。最大产油率所需的最优温度从450℃下降到400℃,最大产油率从34.53%增加到38.71%。

The low-temperature catalytic pyrolysis of sewage sludge is a new developing technology with the dual characteristics of sludge treatment and energy recovery. It was used to treat sludge produced by an urban wastewater treatment plant. Pyrolysis conditions, like residence time and pyrolysis temperature and catalyst, were studied. Results showed that using catalyst decreased the char fraction yield and increased the oil fraction yield while that of the quality of oil also improved. Furthermore, the pyrolysis temperature needed for maximising the oil yield fell from 450℃ to 400℃. maximum oil yields increased from 34.53% to 38.71%, and the heating value ofoil was higher.
