  • Patent number: 4419456
    Abstract: A method for utilizing shot coke which is in the form of hard-to-grind 4 mm spherical particles comprises fluidizing the shot coke particles in a first pressurized reactor vessel and introducing sufficient oxygen and steam to produce a synthetic gas containing carbon monoxide and hydrogen, fluidizing a bed of shot coke particles contained in a second pressurized reactor vessel with the synthetic gas and introducing sufficient oxygen to combust the synthetic fuel and produce water and sufficient heat such that water can react with the shot coke particles to regenerate carbon monoxide and hydrogen. The synthetic gas formed in the second reactor vessel can be recovered at sufficient pressures to drive a power turbine or used to obtain hydrocarbon fuels. A heat recovery system in the second reactor vessel produces steam by indirect heat exchange of the shot coke bed with water. The steam that is generated can be used to supply both the first and second reactor vessels with reactive steam.

  • Patent number: 4413153
    Abstract: The synthetic fuel slate of products derived from wet natural gas is expanded to include both aromatic gasoline from the methane rich dry gas portion via steam reforming to synthesis gas, the production of methanol from synthesis gas and the conversion of methanol to gasoline over a ZSM-5 type catalyst, plus high quality jet fuel, diesel fuel and lubricating oils from the C.sub.3.sup.+ paraffin rich fraction of wet natural gas via thermal cracking of the paraffin rich fraction to olefins and the conversion of the olefins to gasoline and distillate boiling range hydrocarbons over a ZSM-5 type catalyst. Methane separated from the thermal cracked product can be mixed with the dry gas fraction for synthesis gas production and a portion of the hydrogen from the synthesis gas may be used to hydrogenate the distillate fraction from the catalytic conversion of the thermal cracked product.

  • Patent number: 4410336
    Abstract: A process for producing pressurized pipeline gas wherein coal is gasified in oxygen at a relatively low pressure, typically less than 5 atmospheres, to produce a raw gas containing carbon monoxide, hydrogen, carbon dioxide, gaseous sulfur compounds and particulates. A major portion of the raw gas is cooled, cleaned and methanated to produce a pipeline quality product gas consisting essentially of methane. The remaining portion of the raw gas is cleaned, compressed and combusted to produce a high temperature, high pressure flue gas which is used to power a gas turbine and generate steam to power a steam turbine. The gas turbine and steam turbine each drive compressors for compressing the low pressure product gas to pipeline pressure.

  • Patent number: 4407973
    Abstract: The present invention is directed to a process which uses the methanol synthesis gas from steam reforming in a first methanol plant and effectively integrates a second methanol plant which uses as the methanol synthesis gas (a) the purge gas from the first methanol plant and (b) the clean syn-gas produced by partial oxidation.

  • Patent number: 4351742
    Abstract: Crude gas obtained through partial oxidation of carbon-containing material is subjected to catalytic conversion in an apparatus containing a moistening-demoistering system connected by means of a combined water circulation. To reduce the required amount of steam and process heating, a partial stream of water coming from the moistener is branched off, heated by indirect heat exchange with converted, hot synthesis gas, and then united with the partial stream of water coming from the demoistener for re-delivery to the moistener.

  • Patent number: 4341531
    Abstract: Methane-rich gas is produced by reacting gas mixtures comprising CO and at least one member selected from the group consisting of H.sub.2 and H.sub.2 O, such as synthesis gas, in a reactor containing an improved unsupported catalyst comprising an alkali-metal promoted partially reduced mixture of at least one nickel uranate and at least one oxide of nickel. The weight percent uranium present in the activated catalyst, based on total weight of catalyst composition, is in the range of over 50 to about 90.

  • Patent number: 4277416
    Abstract: A system for processing coal to produce methanol, alcohol-slurry coal for transport, electric power and urea. Raw coal is graded. The downgraded fraction is gasified, producing steam and synthesis gas. The synthesis gas is converted to methanol which is then used to slurry upgraded coal for transport or to produce electric power. The steam output of the gasifier drives an oxygen generator to produce oxygen for the gasifier, when the synthesis gas is used to produce methanol, and also drives an electric power turbine. Natural gas may be used to maximize methanol production. Urea is a by-product.
