    摘要： Methods and devices for controlling the reaction of a hydrocarbon to an acid by making phase-related adjustments are disclosed. In order to improve reaction rate and reactivity of the oxidation, a single phase at the operating temperature is attained and maintained by adjusting one or more of gaseous oxidant flow rate, pressure in the reaction zone, temperature in the reaction zone, feed rate of hydrocarbon, feed rate of solvent, feed rate of water if water is being fed, feed rate of the catalyst and other parameters. Methods and devices are also disclosed, wherein a hydrocarbon is reacted at a steady state with a gaseous oxidant to form an acid in a liquid mixture. The amount of water is maintained between a maximum level of water, over which maximum level the substantially single liquid phase is transformed to two liquid phases, and a minimum level under which catalyst precipitates. Further, methods are disclosed, wherein the temperature of the mixture is lowered to a point at which solid dibasic acid is precipitated, while maintaining a single liquid phase, and optionally all the catalyst in solution. At least part of the formed acid is then removed. The preferred hydrocarbon is cyclohexane, the preferred acid is adipic acid, the preferred solvent is acetic acid, and the preferred catalyst is cobalt(II) acetate tetrahydrate.

    摘要： This invention relates to methods for controlling the oxidation of hydrocarbons to dibasic acids, in the presence of a catalyst and a monobasic acid, by removing the catalyst from the reaction mixture, outside the oxidation zone, after the oxidation has taken place at least partially. Initially, the catalyst is partially precipitated and removed by reducing the water level in the reaction mixture and/or subjecting the reaction mixture to a temperature, at which or over which catalyst precipitates. After the initial partial precipitation of the catalyst, the remaining catalyst is subjected to a thermal treatment, during which at least part of the monobasic acid is removed leaving behind molten dibasic acids, in which, at least a major part of the remaining catalyst is precipitated, and it is removed. A minor part of remaining catalyst is removed by methods, which include but are not limited to ion exchange, precipitation with a base or appropriate salt, and electrodialysis. The precipitated catalyst in the three removal stages may be recycled in miscellaneous ways. The dibasic acid(s) may be removed at least partially before or after any catalyst precipitation stage.

    摘要： This invention relates to methods of replacing water and cyclohexanone with acetic acid in an aqueous solution of catalyst, preferably a cobalt compound. Such an aqueous solution is produced by extracting catalyst with water from a cyclohexanone/water solution of reaction products made by the direct oxidation of cyclohexane to adipic acid. The replacement of both water and cyclohexanone are conducted in a solvent exchange column, wherein acetic acid dissolves the catalyst, while water vapors force the cyclohexanone into a condenser, followed by a decanter wherein two liquid phases may be formed and separated; an upper liquid phase containing a majority of cyclohexanone and a lower liquid phase containing a majority of water. The cyclohexanone may be removed in a pretreatment zone, wherein also part of the water may be removed, before the concentrated catalyst extract enters the solvent exchange column.

    摘要： A catalytic composite, its method of manufacture and use is disclosed. The composite comprises a zeolitic crystalline aluminosilicate dispersed in a porous inorganic oxide carrier material comprising silica, alumina or zirconium and a constituent comprising the ions of one or more rare earths with the weight ratio on a volatile free basis of the rare earth ions to the carrier material being greater than 1.0:100.0. The method of manufacture of the composite comprises mixing a catalyst powder comprising the zeolite dispersed in a porous inorganic oxide carrier material with a solution of a salt of the rare earth, separating a filter cake from the slurry by a means not involving the washing of the filter cake and calcining the filter cake. The catalytic composite may be used in a process for cracking a hydrocarbon charge stock.
