通过热化学液化将垃圾直接转化为石油，以液体燃料的形式回收能量。含水量约90%的垃圾由卷心菜、米饭、煮干的沙丁鱼、黄油、蛤壳混合而成。将混合物在加压氮气下于250°、300°或340°C加热0.1、0.5或2小时，使用或不使用碳酸钠作为催化剂（0或4%，基于干燥固体）。油的产率及其性质很大程度上取决于催化剂的添加量和反应温度，而保持时间没有显示出明显的影响。在以下条件下以有机基计获得最高收率27.6%的油：催化剂添加量4wt%；温度，340℃；压力，18兆帕；保持时间0.5小时。该油的热值为 36 MJ kg−1，50°C 时的粘度为 53,000 mPas。其碳含量、氢含量、氮含量和氧含量分别为73.6%、9.1%、4.6%和12.7%。
Garbage was converted directly into oil by thermochemical liquefaction for the recovery of energy in the form of liquid fuel. The garbage with a moisture content of about 90 wt% was prepared by mixing cabbage, boiled rice, boiled and dried sardine, butter, and the shell of short-necked clam. The mixture was heated under pressurized nitrogen at 250°, 300°, or 340°C for 0.1, 0.5, or 2 h, with or without sodium carbonate as a catalyst (0 or 4% on a dry solid basis). Oil yield and its properties strongly depended on catalyst addition and reaction temperature, while holding time showed no marked effect. Oil was obtained in the highest yield of 27.6% on an organic basis under the following conditions: catalyst addition, 4 wt%; temperature, 340°C; pressure, 18 MPa; and holding time, 0.5 h. The oil had a calorific value of 36 MJ kg−1and a viscosity of 53,000 mPas at 50°C. Its carbon content, hydrogen content, nitrogen content and oxygen content were 73.6, 9.1, 4.6 and 12.7%, respectively.
