Abstract
A production process includes combining a first feed stream and a second feed stream to produce, in a pre-reforming reactor, a first product stream comprising CH4 and H2O; wherein the first feed stream contains a mixture of H2 and at least one selected from the group consisting of hydrocarbons having two or more carbon atoms and alcohols having two or more carbon atoms, and the mixture has a hydrogen stoichiometric ratio (λ) of at least 0.1, and the second feed stream contains steam; feeding the first product stream into a reforming reactor; and reacting the first product stream in the reforming reactor to produce a second product stream containing CO and H2; and a catalyst for use in the process. Conversion of the second product stream to synthetic crude, methanol, higher alcohols, and/or DME may also be undertaken. Yet further conversion of a synthetic crude to lubricants, diesel and the like, and/or the alcohols/DME to gasoline, olefins, and/or other oxygenates may also be included.
