| An integrated polygeneration system and process is disclosed for generating liquid hydrogen as a main energy product for use as a propellant for space vehicles. Secondary energy products and commodities for supporting a space center complex and launching of the space vehicle includes the production of electrical and thermal energy and gaseous nitrogen. The integrated process includes a coal gasification and gas cleanup system (12), a combined cycle power generation system (18), a hydrogen production and liquefaction system (22) and a air separation system (32). A medium BTU gas (16) is produced by the coal gasification system and is delivered at (16a) to the power generation system and (16b) the hydrogen production and liquefaction system. Steam (14) also produced in the coal gasification process is delivered to a steam turbine in the combined cycle power generation system which is combined with a gas turbine to which the medium BTU gas is delivered to generate electrical and thermal power in a combined cycle power generation process. Steam from the coal gasification process is also delivered to a shift conversion unit in the hydrogen production system to increase the hydrogen content of the medium BTU gas prior to liquification. Air separation system (32) produces oxygen and gaseous nitrogen. The oxygen is utilized in the coal gasification process and the gaseous nitrogen is delivered for storage to a launch complex site where it is used as an inert gas to purge critical environments. The gaseous nitrogen is also utilized in the hydrogen production system where the nitrogen is liquified and used to refrigerate the hydrogen. | ||||||

C. to allow a single-step treatment. | ||||||
| 146 | Process and apparatus for conversion of water vapor with coal or hydrocarbon into a product gas | US750909 | 1985-07-01 | US4713234A | 1987-12-15 | Walter Weirich; Heiko Barnert; Michael Oertel; Rudolf Schulten |
| A process and apparatus for convertion of steam and hydrocarbon, or steam and coal, into a product gas which contains hydrogen. The conversion rate is augmented by effective extraction and removal of hydrogen as and when hydrogen is generated. Within a reaction vessel wherein the conversion takes place, a chamber for collection of hydrogen is formed by the provision of a hydrogen-permeable membrane. The chamber is provided with a hydrogen extraction means and houses a support structure, for example, in the form of a mesh providing structural support to the membrane. The membrane may be of a pleated or corrugated construction, so as to provide an enlarged surface for the membrane to facilitate hydrogen extraction. Also, to further facilitate hydrogen extraction, a hydrogen partial pressure differential is maintained across the membrane, such as, for example, by the counter pressure of an inert gas. A preferred configuration for the apparatus of the invention is a tubular construction which houses generally tubular hydrogen extraction chambers. | ||||||

| A process for removing methane or oxygen from gases containing the same comprises adding to the gas an amount of oxygen or methane, respectively, which is sufficient to provide, together with any oxygen or methane already present, a stoichiometric excess over the impurity to be removed, and contacting the resulting gas mixture with a catalyst comprising one or more of the metals platinum, palladium, osmium, iridium, ruthenium, rhodium, or silver, to effect combustion and thereby remove the impurity. Quantitative removal of either methane or oxygen from nitrogen, argon, helium, neon, carbon dioxide, and mixtures of any of them, may be effected. The catalytic metal may be in the form of granules, pellets, or powder, may be supported on activated alumina, silica gel, silica, or diatomaceous earth, and may constitute 0,05 to 5% by weight of the total catalyst composition. Natural gas may be used as a source of methane. The reaction pressure may be atmospheric to 500 p.s.i.g., and ignition temperatures as low as 271 DEG C. may be obtained for the methane-oxygen reaction. Specification 879,209 is referred to. | ||||||
