Abstract

The formation of carbonaceous deposits on a platinum black catalyst was studied using two methods: measuring its loss of aromatizating activity and direct viewing by an electron microscope. Open chain hydrocarbons showed higher deactivating effect than cyclic ones, including benzene. This may be due to the trans-polyene precursors of coke formation. Carbonaceous deposits have been seen both as amorphous layers and whiskers, after passing only a few mg of unsaturated hydrocarbons. The surface carbon formation is evaluated as a rapid catalytic intermolecular reaction between unsaturated chemisorbed species. A panel discussion is included.
