Abstract
A method for obtaining an olefin is disclosed, the method comprising subjecting a paraffin to dehydrogenation in the absence of oxygen and in the presence of a catalyst comprising a crystalline substrate, to obtain an olefin. The catalyst includes an inert stabilizing agent for maintaining the catalyst crystal structure. The catalyst may be regenerated by being subjected, in air, to a temperature between about 550° C. and about 750° C., for a period of time between about 15 minutes and about 4 hours.
