Title (EN) A PROCESS FOR THE DEHYDROGENATION OF ALKANES TO ALKENES AND IRON-BASED CATALYSTS FOR USE IN THE PROCESS
(FR) PROCÉDÉ DE DÉSHYDROGÉNATION D'ALCANES EN ALCÈNES ET CATALYSEURS À BASE DE FER DESTINÉS À ÊTRE UTILISÉS DANS LE PROCÉDÉ
Abstract:
(EN) In a process for the catalytic dehydrogenation of lower alkanes to the corresponding alkenes, a regenerable catalyst comprising iron carbide supported on a carrier is used. A small amount (below 100 ppm) of a sulfur compound, such as H2S, is added during the process.
(FR) La présente invention concerne un procédé de déshydrogénation catalytique d'alcanes inférieurs en alcènes correspondants en utilisant un catalyseur régénérable comprenant du carbure de fer supporté sur un porteur. Selon l'invention, une petite quantité (inférieure à 100 ppm) d'un composé soufré, tel que H2S, est ajoutée pendant le procédé.
