Abstract: This review summarizes the preparation，catalytic activity and industrial application of new unsupported hydrotreating catalysts. The advantages and limitations of unsupported hydrotreating catalysts are discussed. Industrial application has proved that unsupported hydrotreating catalysts show higher catalytic activity than supported ones and can meet the requirements for clean fuel. Finally，prospects for the synthesis and application of unsupported hydrotreating catalysts are discussed.
