Abstract: Hydrodechlorination(HDC) of CCl4 to CHCl3 is an economically and environmentally attractive alternative for CCl4 disposal. This review deals with the recent progress of catalytic hydrodechlorination of carbon tetrachloride，including active components，deactivation and pretreatment of catalysts and reaction mechanism. The influence of reaction temperature，pressure and H2/CCl4 molar ratio on the distribution of products of hydrodechlorination reaction of CCl4 is discussed. The future trend in the development of hydrodechlorination of carbon tetrachloride is presented.
