摘要： The invention is directed to a method of fueling gas turbines from natural gas reserves with relatively low methane concentrations. The invention uses such reserves to generate electric power. The invention permits the use of these reserves at significantly lower cost than by producing pipeline natural gas to fuel gas turbines to generate electric power. These reserves currently generally are used only after the removal of impurities to produce pipeline natural gas quality turbine fuel. The latter current technology is capital intensive, and at current natural gas prices, economically unattractive. The process of the invention can remove the impurities from the gas from the natural gas reserve necessary for protection of the environment, and leaves inert gasses in the fuel in an amount which will increase the output of a gas turbine for the generation of power by about 5 to about 20 %.
摘要翻译：本发明涉及一种从具有较低甲烷浓度的天然气储备燃料燃气轮机的方法。本发明使用这种储备来产生电力。本发明允许以比通过向燃料燃气轮机生产管道天然气以产生电力的成本低得多地使用这些储备。这些储量目前一般仅在清除杂质后才能使用，以生产管道天然气质量的涡轮燃料。后者目前的技术是资本密集型的，目前的天然气价格在经济上没有吸引力。本发明的方法可以从保护环境所需的天然气储备中除去气体中的杂质，并将燃料中的惰性气体以一定的量使燃气涡轮机的输出增加约一 5至约20％。

摘要： Motor vehicle parts based on an ethylene, alpha-olefin, diene monomer elastomeric polymers exhibit excellent low temperature compression set. Previously, such compression set performance in the amorphous region was believed to be non-responsive to ethylene content once the amorphous region was reached. However, within certain ranges, ethylene content has been shown to have an effect on low temperature compression set even in the amorphous region. These motor vehicle parts are particularly useful where extremes of ambient temperatures maybe incurred. In a preferred embodiment, the invention is a vehicle part, such a brake part or belt including an ethylene, alpha -olefin, diene elastomeric polymer. The elastomeric polymer has a low ethylene content, and the vehicle part made from a compound based on the elastomeric polymer will have improved low temperature compression set. The vehicle part comprises the elastomeric polymer where the polymer has ethylene present in the range of from 50-60 mole percent, ethyldiene norbornene present in the range of from 0.2-5 mole percent and an alpha -olefin, selected from propylene, hexene-1 and octene-1, where the alpha -olefin makes up the remainder of the elastomeric polymer. The ethylene composition distribution of the elastomeric polymer is such that the ethylene in 90 % of the polymer fractions varies by no more than +/- 4 % by weight. The Mw/Mn will be in the range of 2-4, the inherent viscosity in the range of 1.2-3.2 and the Mooney Viscosity (1+4) @ 125 DEG C in the range of from 10-80. The vehicle part will have an instantaneous compression set at -40 DEG C, less than 80 %.

摘要： Alkyl aromatic compounds are converted to alkyl aromatic aldehydes by a carbonylation reaction. The carbonylation catalyst can be a high boiling point carbonylation catalyst which allows for the separation of the aldehyde product by selective volatilization. Alternatively, the carbonylation catalyst can be selected from perfluoroalkyl sulfonic acids having 2 to 18 carbon atoms, perfluoroether sulfonic acids having 2 to 18 carbon atoms, BF3.(ROH)x wherein R represents CH3 or H and X is a number within the range of from 0.2 to 2, GaBr3, GaCl3, TaF5, NbF5, and NbBr5, with the proviso that when the catalyst is TaF5, NbF5, or NbBr5, then the reaction takes place in the absence of added HF. Preferably, all of the carbonylation reactions take place in the absence of added HF. The alkyl aromatic aldehydes can be oxidized to form an aromatic acid. A mixed xylene feed stock can be converted to a mixture of diemthylbenzaldehydes and then oxidized to form trimellitic acid without the need to separate the xylene or dimethylbenzaldehyde isomers.

摘要： A process for the separation, and removal, of hydrogen, or both hydrogen and carbon monoxide, from a mixture of these gases with olefinic hydrocarbons. In one embodiment, a mixture constituted of hydrogen and one or more reactive unsaturated hydrocarbons is contacted with oxygen or an oxygen-containing gas, over a catalyst at reaction conditions sufficient to oxidize the hydrogen component of the mixture to form water, while suppressing reaction of the reactive unsaturated hydrocarbon. In a second embodiment, there is included a two-reaction-zone series wherein effluent from the first reaction zone, wherein the mixture includes hydrogen, carbon monoxide and at least one reactive unsaturated hydrocarbon, is contacted with oxygen or an oxygen-containing gas, and reacted over an oxidation catalyst at conditions sufficient to oxidize the carbon monoxide component of the mixture to form carbon dioxide and suppress hydrogenation of the reactive unsaturated hydrocarbons. In a third embodiment, there is included a three-reaction-zone series wherein effluent from the second reaction zone, wherein the mixture includes carbon monoxide, water, and at least one reactive unsaturated hydrocarbon, is reacted over a water-gas-shift and hydrogenation catalyst at conditions sufficient to react carbon monoxide component of the mixture to form carbon dioxide and hydrogen, and hydrogenate said reactive unsaturated hydrocarbon with the resulting hydrogen. In each embodiment, reactive unsaturated hydrocarbons denuded of hydrogen, or both hydrogen and carbon monoxide are recovered.
