HIGH-POROSITY FOAM CERAMICS AS CATALYST CARRIERS USED FOR THE DEHYDROGENATION OF ALKANES

摘要

The invention relates to a material which is suited as a carrier for catalystsin the dehydrogenationof alkanes and in the oxidative dehydrogenation of alkanes and which ismade of an oxide ceramic foam and may contain combinations of the substancesaluminiumoxide, calcium oxide, silicon dioxide, tin oxide, zirconium dioxide, calciumaluminate,zink aluminate, silicon carbide, and which is impregnated with one or severalsuitable catalytically active materials, by which the flow resistance of thecatalystdecreases to a considerable degree and the accessibility of the catalyticallyactive materialimproves significantly and the thermal and mechanical stability of thematerial increases.The invention also relates to a process for the manufacture of the materialand a process for the dehydrogenation of alkanes by using the materialaccording tothe invention.
