摘要： There is provided a process for preparation of synthesis gas from feedstocks containing methane and/or higher hydrocarbons having from about 2 to about 12 carbon atoms by an initial catalytic treatment of feedstock to provide a methane-containing gaseous mixture substantially free of compounds having 2 or more carbon atoms, and reforming the gaseous mixture at elevated temperatures using nickel-containing catalytic materials that are unusually active under mild conditions of conversion and resistant to deactivation. The process consists fundamentally in converting the higher hydrocarbon compounds to form the methane-containing gaseous mixture in an initial conversion zone containing a catalyst while controlling temperatures within the initial conversion zone to temperatures in a range downward from about 500° C. to about 300° C., and reforming the methane-containing gaseous mixture in a subsequent zone to form synthesis gas.

摘要： The present invention relates to devices for conducting, simultaneously, exothermic and endothermic chemical conversions with transfer of heat therebetween. More particularly, this invention relates to autothermic modules using oxygen ion-conducting dense ceramic membranes to separate, selectively, oxygen from an oxygen-containing gas and supply it directly to partial combustion of gaseous organic compounds. Processes using autothermic modules in accordance with this invention are, advantageously, used for production of synthesis gas comprising carbon monoxide and molecular hydrogen which synthesis gas is substantially free of deleterious and/or inert gaseous diluents such as nitrogen. In particular, for conversions, within the integral autothermic module, of natural gas or other forms of gaseous lower alkanes to synthesis gas by means of partial combustion followed by reforming.

摘要： Emissions of nitrogen oxides in exhaust from gas turbine systems are reduced, in accordance with the invention, by introducing, into the combustor, a supplementary gaseous stream comprising dihydrogen, carbon monoxide and carbon dioxide, and a stream of gaseous fuel and/or mixtures thereof, with a source of dioxygen to form a combustible gaseous mixture; combusting the mixture to produce heat and a combustion product stream; and driving a turbine with the combustion product stream to produce an exhaust stream and to generate mechanical power. Supplementary gaseous streams are, advantageously, formed by a process for hydroshifting dimethyl ether, i.e. formed by a process 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. This process produces a hydroshifted product stream which is, advantageously, relatively rich in dihydrogen, carbon monoxide, and carbon dioxide.

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.
