Abstract
1,250,786. Dehydrogenation. ESSO RESEARCH & ENG. CO. 31 Oct., 1968 [1 Nov., 1967], No. 51615/68. Heading C5E. [Also in Division C2] Hydrocarbons are dehydrogenated by contact with at least 0À1 mole/mole of O 2 and at least 0À2 mole/mole of Cl 2 in the presence of a catalyst comprising a catalytic support material having a surface area below 100 m.<SP>2</SP>/gm., and at a space velocity in the range 1-5000 v./v./hr. Many suitable materials are mentioned, preferred being alumina, magnesia and silicon carbide. The catalyst may also contain nickel and/or lanthanum as metal, salts, oxides or hydroxides; and these may be promoted by cerium, copper, uranium and/or potassium as metal, salts, oxides or hydroxides. Reaction temperature may be 800-1400‹ F., and an inert diluent is preferably present, e.g. methane, CO 2 , steam, N 3 , He or A. For dehydrogenating ethane, ethylene may be used as diluent. The Cl 2 may be provided as such, or as HCl or other Cl 2 -liberator. The following conversions are mentioned: ethane to ethylene (exemplified) propane to propylene isobutane to isobutylene n-butane to butene and/or butadiene (exemplified) methyl butene to isoprene ethylbenzene to styrene isopropylbenzene to alpha-methylstyrene ethylcyclohexane to styrene cyclohexane to cyclohexene and/or benzene cyclopentane to cyclopentene and/or cyclopentadiene.
