摘要： A method for preparing a supported carbon catalyst, the method includes at least the following steps: contacting a gas containing an organic silicon source with a silicon oxide-based material to obtain a precursor; contacting the precursor with a gas containing an organic carbon source to obtain the supported carbon catalyst. The temperature and energy consumption of the chemical vapor deposition of heteroatom-containing carbon material on silica-based materials can be greatly reduced in this method, and the cost of the catalyst can be effectively reduced.

摘要： Processes and systems for dehydrogenating ethylbenzene may include mixing a steam stream and an ethylbenzene stream to form a feed mixture. The ethylbenzene/steam feed mixture may then be fed to a dehydrogenation reactor containing an alkali metal promoted catalyst. A liquid, selected from an alkali metal liquid, an alkali metal compound liquid, or a liquid solution comprising an alkali metal, may be injected into a feed stream, such as the steam stream, the ethylbenzene stream, or the ethylbenzene/steam feed mixture. Following injection, the liquid vaporizes and disperses into the feed stream upstream of the dehydrogenation reactor. The liquid may be maintained as a liquid from a point upstream of injection to an injection nozzle. The liquid is dispersed through the injection nozzle, in liquid form, to form droplets of liquid dispersed in the feed stream, which evaporate and/or dissolve into the vaporous feed stream.

摘要： A method including contacting an organic stream with water and carbon dioxide, whereby sodium is extracted from the organic stream, and separating an aqueous sodium salt-containing phase from an organic phase comprising a reduced sodium content. The organic stream can be a heavy residue formed in the co-production of propylene oxide and styrene. Contacting can include combining the carbon dioxide with the water to form a CO2-saturated water stream and contacting the CO2-saturated water stream with the organic stream, and/or combining the organic stream and the water to form a mixture and injecting the carbon dioxide as a gas thereinto. The method can further include repeating the contacting and the separating one or more times on the organic phase, subjecting the organic phase to ion exchange, or both, to obtain an organic phase having a further reduced sodium content. A system for carrying out the method is also provided.
