    摘要: In a preferred embodiment, the invention relates to a process of sequestering carbon dioxide. The process comprises the steps of: (a) reacting a metal silicate with a caustic alkali-metal hydroxide to produce a hydroxide of the metal formerly contained in the silicate; (b) reacting carbon dioxide with at least one of a caustic alkali-metal hydroxide and an alkali-metal silicate to produce at least one of an alkali-metal carbonate and an alkali-metal bicarbonate; and (c) reacting the metal hydroxide product of step (a) with at least one of the alkali-metal carbonate and the alkali-metal bicarbonate produced in step (b) to produce a carbonate of the metal formerly contained in the metal silicate of step (a).

    摘要: The natural gas is deacidized by contacting in zone 3 with a solvent containing amine in aqueous solution. The gas is then dehydrated by contacting in zone 4 with a solvent very rich in amine. After the contacting operations, the solvent containing H2S. and water is expanded in drum 9, then regenerated in column 11. Part of the regenerated solvent is sent to zone 3. Another part of the regenerated solvent is vacuum distilled in column 18 so as to produce an amine-rich solvent that is sent to zone 4.

    摘要: A catalyst (5) for selectively oxidizing carbon monoxide, wherein a noble metal (3) and an active oxygen supply material (4) capable of oxidizing carbon monoxide are supported on a substrate (6). Favorable selective oxidation of carbon monoxide can be obtained by setting the distance between the noble metal (3) and the active oxygen supply material (4) such that the noble metal (3) is close enough to accept active oxygen from the active oxygen supply material (4), and preferably within 0.1 mm. This catalyst (5) for selectively oxidizing carbon monoxide is effective at removing carbon monoxide from a reformate gas whose main component is hydrogen and which is supplied to a fuel cell.

    摘要: I have recognized diamond carbon as a unique form of carbon. It is primordial carbon owing to the fact that natural diamonds are billions of years old and that diamonds do not change form chemically nor are they mechanically changed due to the fact that they are the hardest natural substance. The burning or transformation of a diamond into another form of its unique carbon marks a specific moment in an immense span of time. If not acted upon consciously by man the diamond would continue to endure for billions more years. The connection of these thoughts and realizations and the infusion of transformed diamond carbon in making Diamond Water and adding value to other products is my invention.

    摘要翻译: 我已经认识到金刚石碳是一种独特形式的碳。 由于天然钻石数十亿年,钻石不会化学变化,也不会由于天然钻石是最硬的天然物质而机械地改变,因此是原始碳。 将钻石燃烧或转化成另一种形式的独特碳标志着巨大的时间跨度的特定时刻。 如果不是有意识地采取行动,钻石将继续忍受数十亿年。 这些想法和实现的联系以及转化的钻石碳在制造钻石水中以及为其他产品增加价值的注入是我的发明。

    摘要: The invention provides processes for selectively oxidizing carbon monoxide from an input gas stream that contains carbon monoxide, oxygen and hydrogen. The process includes the step of contacting the input gas stream with a preferential oxidation catalyst. The preferential oxidation catalysts are copper-based catalysts containing low concentrations of platinum group metals. In some embodiments, the processes of the invention are conducted using preferential oxidation catalysts having an oxide support on which is dispersed copper or an oxide thereof, a platinum group metal and a reducible metal oxide. In other embodiments, the processes of the invention are conducted with a preferential oxidation catalysts having a cerium oxide support on which is dispersed copper or an oxide thereof and a platinum group metal.

    摘要: The fumes from gas turbine TG are cooled by heat exchangers E1, E2, E01, E02 and E03 and compressed by compressors C1 and C2. The cold and high-pressure fumes are depleted in carbon dioxide in treating plant 10. The fumes depleted in carbon dioxide are heated by heat exchangers E1 and E2, and expanded by turbines T2, then T1. The energy recovered in form of heat in exchangers E01, E02 and E03 is converted into mechanical energy by the engine cycle used by turbine T, condenser E and pump P. The mechanical energy is available at the shaft of turbine T.

    摘要: The invention is a method and composition for producing carbon dioxide that is based on the reaction or activation of at least one carbon-containing compound with protons. The carbon-containing compound can be in the form of a powder, an impregnated carrier (e.g. zeolite crystals) or an aqueous solution and is preferably selected from the group consisting of carbonates, bicarbonates or sesquicarbonates. The protons are preferably provided by a proton-generating species such as an acid or metal salt. The method and composition can further include a water-retaining substance and/or a chlorine dioxide-producing compound in accordance with the invention.
