Abstract
Selective chain propagation of ethene to propene (ETP reaction) was made on silica supported cobalt (Co/SiO2) catalyst. It was suggested that the proper conditions for the chain propagation reaction were close to those for the Fischer-Tropsch reaction. When an equimolecular mixture of 12C2-C2H4 and 13C2-C2H4 was contacted on the catalyst, inter-molecular exchange of methylidene, 12C2-C2H4 + 13C2-C2H4 = 2 13C1-C2H4, namely, metathesis, was not occurred in the ETP reaction. And as a result, the selective chain propagation of ethene to propene without metathesis was successfully achieved on Co/Si02 catalyst.
