    Abstract

    The variations in the amounts of alkali and alkaline earth species actually existing on the surface of carbon black in the courses of heat treatment up to 1123 K and steam gasification at 1073 K were investigated, in order to understand the actual amount of catalyst existing on the surface of carbon in the working state. These gasification catalysts were classified into three groups based on the fact that some of them sunk into the bulk of carbon in the course of heat treatment and some of them vaporized from the surface of carbon. It was found that the migration of species into the bulk of carbon was profoundly associated with the reducibility of their oxide state.
