ABSTRACT:
A process for dehydrogenating light paraffins, in particular C.sub.2 -C.sub.5, to obtain the corresponding light olefins, comprising reacting said paraffins with a catalytic system containing platinum, tin and an alumina support and possibly an element of the lanthanide group in a fluidized bed reactor, where the heat required for the reaction is provided by said catalytic system as sensible heat, operating at a temperature of between 500.degree. and 700.degree. C. and at a pressure of between 1 and 2 kg/cm.sup.2, and regenerating said catalytic system by burning the coke which has deposited on the surface of the catalytic system, said regeneration being conducted in air and/or oxygen, if necessary by increasing the temperature of the catalytic system to a suitable level, followed by reduction of said catalytic system with a reducing agent.
