Direct Thermochemical Liquefaction Technology for Treatment of Municipal Sewage Sludge

污泥直接热化学液化技术是国外８０年代开始发展的一项污泥处理兼资源回收技术。它可使污泥中有机质的４０％以上转化为燃料油（热值≥３３ＭＪ／ｋｇ），相应的有机联转化率达到９０％左右。整个过程为一能量净输出过程。本文对其发展源流、研究现状和发展前景进行了综述和讨论。

he direct thermochemical liquefaction technology developed in the 1980s was used in the treatment of sewage sludge and resource recovery.化气Over 40% of organic matter in sewage sludge were converted into a fuel oil with a caloric power of≥33 MJ/kg while TOC being converted at a rate of up to about 90%. The whole process was found to be a net energy exporting process. A review was also given on the development, current status and prospect of this Process.
