    摘要: Fuel for satisfying low, normal and high electric power generation requirements is obtained from coal in the form of syngas and dimethyl ether fired in turbine-compressor arrangements driving electric generators, wherein the storable ether fuel is fired in turbine-generator arrangements to supplement that normally produced by firing and expanding syngas in appropriate turbine-generator arrangements. High pressure steam generated in the process is expanded in steam turbines to also generate power. Steam product of the combination operation is used in the coal gasification step to produce additional syngas.

    摘要: A process for enhancing the activity of a catalyst metal particulate for hydrogenation reactions comprising calcining the particulate in an oxidant-containing atmosphere to partially oxidize it thereby forming a porous layer of oxides thereon, treating with an solution capable of oxidizing the calcined metal particulate and comprising a compound of a hydrogenation catalyst metal to where said metal particulate has absorbed a volume of solution equal to at least about 10% of its calculated pore volume and activating it by treatment with a hydrogen-containing gas at elevated temperatures thereby forming a dispersed active metal catalyst. Preferably, the treated particulate is calcined a second time under the same conditions as the first before final activation with a hydrogen-containing gas. The metal particulate is preferably sized after each calcination and any agglomerates larger than 250 microns are comminuted to a desired size.

    摘要: There is provided a process for converting methane to carbon disulfide. More particularly, methane is decomposed to form elemental carbon and elemental hydrogen, and the elemental carbon is reacted with sulfur to form carbon disulfide. Carbon disulfide may then be contacted with hydrogen, optionally in the presence of more methane, under conditions sufficient to produce CH.sub.3 SH. This CH.sub.3 SH may then be contacted with a sufficient catalyst, such as a zeolite, especially ZSM-5, under conditions sufficient to produce hydrocarbon having two or more carbon atoms.
