Abstract
Process for the catalytic dehydrogenation of alkylaromatic hydrocarbons optionally mixed with ethane which comprises: A) dehydrogenating the hydrocarbon stream, optionally mixed with an inert gas, in a fluid bed reactor in the presence of a catalytic composition based on gallium and manganese supported on alumina modified with silica, at a temperature ranging from 400 to 700° C., at a total pressure ranging from 0.1 to 3 ata and with a GHSV (Gas Hourly Space Velocity) ranging from 50 to 10,000 h; and B) regenerating and heating the catalyst, by means of the catalytic oxidation of a fuel, in a fluid bed regenerator at a temperature higher than 400° C.
