摘要： A process for hydrogenating carbon dioxide to generate methanol. In the process, a strip of copper base plate is transported by the groups of rotating drive rollers to deposit porous metallic zinc on the copper base plate. Hydrogen is generated from the porous metallic zinc upon electrochemical reactions in the inner space sealed with the above groups of rollers. Simultaneously, zinc oxide and copper oxide catalysts are formed on the porous metallic zinc. Carbon dioxide is introduced into the sealed inner space under high-temperature and high-pressure to generate methanol by hydrogenation.

摘要： The present invention relates to a method and apparatus for reducing the maximum water concentration in multi-phase reactors operating at Fischer-Tropsch conditions. In a preferred embodiment of the present invention, a method of reducing the maximum concentration of water in a multi-phase reactor containing an expanded slurry bed and a water-rich slurry region for Fisher-Tropsch synthesis includes changing the flow structure of a predetermined region in the reactor. The flow structure may be changed by introducing a mixing enhancing fluid into the predetermined region, installing baffles into the predetermined region, or by other methods known in the art. Preferably the predetermined region is located between null H and H and between null R and R, where H is the height of the expanded slurry bed and R is the radius of the reactor.

摘要： The present invention is a novel process for methanol production in a liquid phase reactor from a synthesis gas comprising of hydrogen, carbon dioxide and carbon monoxide. The liquid phase reactor contains a solid catalyst suspended in methanol. In this innovation, methanol acts both as a product and as a suspension medium for the catalyst. The new innovation exploits the condensing conditions for methanol production. By operating at condensing conditions, the methanol partial pressure at equilibrium is higher than the boiling pressure of methanol at the given temperature. Hence the produced methanol of the equilibrium composition condenses creating the potential of more gas to be converted. Since equilibrium is not a limiting factor, high conversions can be obtained.

摘要： A method of increasing the production in an existing process plant for converting natural gas into a product, where the natural gas is first converted to a synthesis gas in a synthesis gas section, the synthesis gas is brought to reaction in a reactor for synthesis of the product, where non-converted synthesis gas and product are separated into two streams, where a product-rich stream is taken off the process, while a product-poor stream is re-circulated back as feed to the reactor together with fresh synthesis gas, and where part of the re-circulating stream is taken off the re-circulation loop as a purge gas, where the purge gas is separated into hydrogen-rich and hydrogen-poor streams, where hydrogen-rich streams are introduced in stages of the process where addition of hydrogen is desirable, and where the residual thermal value of the hydrogen-poor stream may be used for heating prior to the stream being discharged, wherein the synthesis gas from the synthesis gas section receives a hydrogen-rich stream from the separated purge gas, and that this hydrogen enriched synthesis gas is passed through a new flow reactor for production of product, and also a unit for separating a product-rich stream that is taken off, and a product-poor stream used as feed to the original reactor, and that the product-poor stream, which is used as feed to the original reactor, receives additional synthesis gas produced in a separate secondary synthesis gas line, is described. Additionally, a process plant for carrying out the method is described.

摘要： A process for the purification of fluoromethyl hexafluoroisopropyl ether which involves contacting a crude composition fluoromethyl hexafluoroisopropyl ether and hexafluoroisopropyl alcohol with a modifier to modify the vapour pressure of the ether and/or the alcohol. The difference in vapour pressure of the ether and the alcohol increases relative to the difference in vapour pressure of the ether and alcohol in the absence of the modifier and enables separation of the ether from the alcohol. The modifier suitably is ammonia and/or an amine.
