Alkanes are dehydrogenated in one embodiment by passage through alternating dehydrogenation zones and selective oxidation zones), in which latter zone(s) hydrogen produced in the preceding endothermic dehydrogenation reaction is selectively oxidized to generate heat for the succeeding dehydrogenation reaction. In one embodiment, dehydrogenation is carried out without limitation to particular flow sequence using a catalyst, comprising an alloy or combination of nickel with copper tin, lead or indium on non-acidic supports. In another embodiment new catalyst compositions, active for dehydrogenation of alkanes are prepared comprising reduced and sulfided nickel crystallites on siliceous …

Why it's free to use
- Filed April 23, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 23, 2013.
