Catalyst deactivation simulation through carbon deposition in carbon dioxide reforming over ni/cao-al 2o 3 catalyst

Major problem in CO 2 reforming of methane (CORM) process is coke formation which is a carbonaceous residue that can physically cover active sites of a catalyst surface and leads to catalyst deactivation. A key to develop a more coke-resistant catalyst lies in a better understanding of the methane r...
