摘要：
The influence of hydrogen sulfide on the kinetics of propane and isobutane dehydrogenation and the properties of supported platinum-alumina catalysts with or without Sn and In additives were investigated. Kinetic equations taking into account the hydrogen sulfide influence and the simple mutual influence of the components were derived. The addition of hydrogen sulfide in a concentration below similar to 0.05% with respect to paraffins did not decrease the activity and selectivity of catalysts, but improved their stability and changed the composition of the coke formed.
