Abstract

1,220,283. Dehydrogenating alkyl aromatics. UNION CARBIDE CORP. 10 June, 1968 [16 June, 1967], No. 27407/68. Heading C5E. Alkenyl aromatics, particularly styrene, are obtained from corresponding alkyl aromatics by an endothermic dehydrogenation process carried out at 500-700‹ C. in the presence of steam and in the absence of oxygen, chlorine or chlorineliberating material, the process taking place in at least one high nickel-containing stainless reactor. Such steel is defined as containing inter alia 17-20 wt. per cent Cr and 8-13 wt. per cent Ni, suitable steels being types 304 and 347. A plurality of reactors may be used, at least one of them (e.g. the first) being constructed of such steel. Heat exchanger(s) may also be of this type of steel. When more than one reactor is used, the effluent from each reactor may be reheated before entering the next. A conventional catalyst may be present, e.g. Fe 2 O 3 / K 2 CO 3 /CrO 3 , MgO/FeO/K 2 CO 3 or Al 2 O 3 /SiO 2 /N 1.
