Abstract: The common methods of direct liquefaction for making liquid fuels，indirect liquefaction for making low-carbon alcohol，F-T synthesis and others were summarized. By investigating specific technical parameters，and reviewing key technologies and problems，the choice of technical route choice and the technical parameters and direction of development were discussed. The solutions to the existing problems of each process were proposed by integrating matured related technologies in chemical industry and new ideas of technical route for organic waste utilization were presented. Finally，the technology and economics of liquid fuel synthesis from organic wastes were propspected.
