Abstract: A process for hydroshifting dimethyl ether is described which comprises passing a feed stream which includes dimethyl ether and steam to a hydroshifting reaction zone including an essentially alkali metal-free catalytic composition substantially composed of copper or nickel in elemental form. The process produces a hydroshifted product stream which is relatively rich in hydrogen, carbon monoxide, and carbon dioxide.The feed stream can be transported relatively easily in liquid form at comparatively low pressures. The hydroshifting reaction zone can include a hydrolysis reaction zone and a water-gas shift reaction zone. The hydrolyzed product and the water-gas shift product can be recovered to obtain hydrogen and carbon dioxide, respectively. Additionally, the hydroshifted product stream can be blended with an oxidizing stream and combusted to drive a turbine in order to generate mechanical energy.

Abstract: A process is effected using water soluble metal complex catalysts in the presence of a promoter in the organic (water immiscible) phase.

The reaction comprises of two phases viz - organic phase and aqueous phase. The organic phase consists of an olefin and P- containing water insoluble ligand with or without water immiscible solvent. The aqueous phase consists of a metal complex catalyst comprising of group VIII element such as Rh, Ru, Ir or Co and a water soluble ligand.

Abstract: An improved method for the production of stoichiometric ratioed syngas comprises partially oxidizing a gaseous feedstock containing substantial amounts of methane in a gasifier to produce a hot synthesis gas stream that is passed in indirect heat exchange through a steam reforming catalytic reactor. A portion of the steam reforming reaction products are mixed with the cooled gasifier synthesis gas stream exiting the steam reforming catalytic reactor to form a combined synthesis gas stream, called a "stoichiometric ratioed synthesis gas." The stoichiometric ratioed synthesis gas stream can then be passed into a methanol synthesis unit at substantially the specifications for optimal methanol production with little or no external compression. In a second embodiment the gasifier unit is arranged and operated in parallel with a primary steam reformer unit.
