Abstrakty

The activity of Co-zeolites with MFI, BEA,MORand FER topologies was studied in propane oxidative dehydrogenation. The products of oxidative dehydrogenation of propane were propene, CO, CO2 and a very small amount of ethene and methane as products of cracking, which play only a minor role. The sequence in ODH activity of Co-zeolites is CoH-BEA > CoH-MFI > CoH-MOR > CoH-FER. The difference in activity of various zeolite matrices is ascribed to the differences of channel diameter and architecture of Co-_ sites in the pentasil zeolites. Rate limiting step of propene formation is not the reaction of propane or adsorbed species of propane with oxygen but desorption of propene.
