Ni supported catalysts were widely used in natural gas chemical industry and coal chemical industry, and carbon deactivation was a predominant factor for catalyst lifetime. Enhancing anti-carbon deposition performances was a key point for Ni supported catalysts. The modes of carbon deposition on Ni catalysts, mechanism of coke formation and its effect on catalyst deactivation were reviewed, and some methods for restraining carbon deposition, including adding assistants, modifying support surface and pore structure and conditioning reaction atmosphere were discussed.
