Abstract: The source and composition of oily sludge,and relating treatment technologies are introduced.Different types,advantages and disadvantages of catalysts commonly used in catalytic pyrolysis technology worldwide are emphatically expounded.The catalytic activities of metal supported molecular sieve catalysts in corresponding research are compared.The affecting factors and mechanism for metal supported zeolite catalyst are investigated,indicating that the addition of metal or metal oxide can improve the efficiency of catalytic pyrolysis of oily sludge based the addition of Lewis acid sites.Possible ideas for catalytic pyrolysis technology of oily sludge,such as improving the quality of products,continuous catalytic pyrolysis technology and the extraction of heavy metal,in the future are presented.
