Properties of surface‐modified alumina catalysts of COS synthesis

The surface electronic structure, the acid-base properties, the component adsorption and the catalytic of gamma alumina (CD-300, Ketjen) modified with surface sodium as a donor-type or iron as an acceptor-type additive have been investigated. Alumina was loaded with 0.1 and 1 wt.% Na and Fe. The catalytic O/S exchange of CO 2 and CS 2 to form COS was applied as a model reaction, for which the kinetic parameters have also been determined
