CATALYTIC PYROLYSIS OF DICHLOROETHANE - CALCULATION OF THE CATALYSIS SPHERE

A method for the calculation of the size of catalysis sphere (that is, the sphere around the catalyst granule containing more chlorine atoms generated by the surface than on the thermal pyrolysis) is proposed. An increase in the number of chlorine atoms capable of chain propagati on comprises the contribution of the heterogeneous catalyst to the rad ical chain nonbranched pyrolysis of dichloroethane. The sphere size is shown to determine the optimal granule size of the catalyst used and its location in the reactor.
