    摘要: A process is disclosed for the synthesis of methanol from methane comprising three reaction steps operated in tandem. In the first step methylene chloride is produced by the reaction of methane with oxygen and hydrogen chloride. In the second step, methylene chloride is hydrolyzed to formaldehyde, which is hydrogenated in the third step to provide the product methanol.

    摘要: This invention is a process for producing vinyl chloride from an ethylene-containing feed, oxygen, and a chlorine source in the presence of a catalyst. The process permits direct production of vinyl chloride in a single reactor system, and further permits ethane to be used as the C2 hydrocarbon feed with recycle of ethylene from the product stream to constitute the ethylene specified for the feed. This invention in another aspect concerns also a composition of matter, and a method for making the composition, wherein the composition is useful as a catalyst for the vinyl chloride process. The composition comprises a rare earth-containing material, with the proviso that the catalyst prepared therefrom is substantially free of iron and copper and with the further proviso that when cerium is present the catalyst further comprises at least one more rare earth element other than cerium.

    摘要: An improved process is disclosed for manufacturing chlorinated hydrocarbon by way of oxychlorination which yields reduced levels of environmental toxins such as, chlorobenzenes, polychlorinated biphenyls, polychlorinated dibenzodioxins and polychlorinated dibenzofurans. The process involves fixed bed or fluid bed catalyzed oxychlorination of a hydrocarbon reactant containing from 1 to 3 carbon atoms. The oxychlorination process consists of contacting the hydrocarbon reactant with oxygen or oxygenated gas and at least a portion of externally obtained hydrogen chloride in the presence of the oxychlorination catalyst in a heated reaction zone operated at from 150° C. to 600° C. and recovering chlorinated hydrocarbon from the effluents of the reaction zone. The improvement consists of the use of at least a portion of the hydrogen chloride from an external source other than from recovery of hydrogen chloride from the thermal pyrolysis of the product from the operated oxychlorination process, wherein the external hydrogen chloride, containing aromatic hydrocarbons, is pretreated before use in the operated oxychlorination process by a means for removal of the aromatic hydrocarbons.

    摘要: A process is disclosed for the production of aromatic-rich, gasoline boiling range hydrocarbons from the lower alkanes, particularly from methane. The process is carried out in two stages. In the first, alkane is reacted with oxygen and hydrogen chloride over an oxyhydrochlorination catalyst such as copper chloride with minor proportions of potassium chloride and rare earth chloride. This produces an intermediate gaseous mixture containing water and chlorinated alkanes. The chlorinated alkanes are contacted with a crystalline aluminosilicate catalyst in the hydrogen or metal promoted form to produce gasoline range hydrocarbons with a high proportion of aromatics and a small percentage of light hydrocarbons (C.sub.2 -C.sub.4). The light hydrocarbons can be recycled for further processing over the oxyhydrochlorination catalyst.

    摘要: An alkane is reacted with oxygen and available chlorine in the presence of a solid solution catalyst containing iron cations to yield unsaturated hydrocarbons and chlorinated saturated and unsaturated hydrocarbons. In a preferred embodiment of the process, ethane is reacted with oxygen and available chlorine in the presence of a solid solution catalyst containing iron cations to yield vinyl chloride, ethylene, and other valuable by-products. The conversion of ethane to products approaches 100 percent, vinyl chloride is prepared in up to 40 mole percent yield, and the combined yield of vinyl chloride, ethylene dichloride, ethyl chloride, and ethylene is up to 90 mole percent.
