Abstract
The oxidative coupling of methane (OCM) and the oxidative dehydrogenation (ODH) of ethane and higher hydrocarbons is described using SO3 and sulfate, sulfite, bisulfite and metabifulfite salts as oxygen transfer agents in the presence of one or more elements selected from Groups 3 to 14 of the periodic table, optionally further in the presence of alkali or alkaline salts and/or sulfur-containing compounds.
Claims15
A method of oxidatively dehydrogenating a saturated hydrocarbon feed to produce a dehydrogenated hydrocarbon product and water, the method comprising:
- contacting the saturated hydrocarbon feed at the same or different times with
- (a) calcium sulfate (CaSO4),
- (b) W and at least one of Fe and/or Mn, and
- (c) an alkali metal salt, and
- oxidatively dehydrogenating the hydrocarbon feed to produce the dehydrogenated hydrocarbon product and the water.
