    摘要: 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.

    摘要: A composition consisting essentially of a carbonaceous solid containing at least one carboxyl group is heated with subcritical liquid water at decarboxylation conditions including a temperature of at least about 300.degree. F. to substantially decarboxylate the solid, thereby producing a stream comprising a decarboxylated solid and water. The water is separated from the decarboxylated solid prior to liquefying the solid.

    摘要: A process for recovering sulfur from a hydrogen sulfide-bearing gas utilizes an aqueous reaction medium, a temperature of about 110-150° C., and a high enough pressure to maintain the aqueous reaction medium in a liquid state. The process reduces material and equipment costs and addresses the environmental disadvantages associated with known processes that rely on high boiling point organic solvents.

    摘要: A method of generating power by passing a dimethyl ether-containing fuel to a dry low NOx combustor of a fired turbine-combustor in the presence of an oxygen-containing gas for combustion in the combustor to form flue gas, and then passing the flue gas to the turbine to generate power, wherein the fuel comprises a mixture of dimethyl ether, at least one alcohol and, optionally, a component selected from the group consisting of water and C1-C6 alkanes. The fuel composition used in the inventive method permits a safe and highly efficient operation of a dry low NOx combustion system, while at the same time, minimizing the generation of NOx and carbon monoxide emissions.
