摘要

1487086 Isobutane ATLANTIC RICHFIELD CO 29 Nov 1974 [27 Feb 1974] 51858/74 Heading C5E Isobutane is prepared by dehydrating and hydrogenating, in a single reaction stage, tertiary butyl alcohol at 450-850‹ F. with H 2 at a partial pressure of H 2 of 150-350 p.s.i. at the reactor outlet in the presence of a supported nickel metal catalyst or a supported sulphided nickel-molybdenum catalyst. The catalyst may be sulphided Ni-Mo on alumina, and sulphur may be introduced with the tertiary butyl alcohol feed in an amount of at least 50 p.p.m. on a molar basis. Alternatively, the catalyst may be nickel on kieselguhr.
