    摘要: To present an oil-forming method of chlorine-containing plastic refuse capable of obtaining oily product free from chlorine content, while suppressing apparatus corrosion by efficiently capturing hydrogen chloride generated by decomposition of chlorine-containing plastics, the oil-forming method of chlorine-containing plastic refuse is characterized by decomposing chlorine-containing plastic refuse using water in supercritical region as reaction medium and forming into oil, wherein silver nitrate of 0.8 to 2.0 times the reaction equivalent amount of hydrogen chloride generated by decomposition of chlorine-containing plastic refuse is added in the water as reaction medium to decompose and form into oil, and generated hydrogen chloride is removed in a form of silver chloride.

    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: In a process for producing alkylaromatics by halogenating a paraffin and reacting the halogenated paraffin with an aromatic hydrocarbon, the rate of halogenation is improved by treating the n-paraffin to selectively remove oxygen-containing hydrocarbonaceous compounds from the n-paraffin with a sorbent selective for such oxygen-containing compounds, and subsequently halogenating the treated n-parffin. The improvement is particularly useful in producing alkylaromatic hydrocarbons from monocyclic aromatic compounds and n-paraffins.

    摘要: THE PRESENT INVENTION RELATES TO AN IMPROVED PROCESS FOR PRODUCING FREE HALOGEN FROM HYDROGEN HALIDE AND UTILIZING THE FREE HALOGEN PRODUCED IN HALOGENATION REACTIONS. THE HYDROGEN HALIDE PRODUCED IN REACTIONS WHEREIN A HYDROCARBON FEED STREAM IS HALOGENATED, OR REACTIONS WHEREIN A HYDROCARBON FEED STREAM IS HALOGENATED AND THEN USED TO ALKYLATE A CYCLIC ORGANIC COMPOUND, IS OXIDIZED TO FORM AN EFFLUENT GAS STREAM CONTAINING FREE HALOGEN, WATER AND OTHER GASES. IN ONE ASPECT OF THE PRESENT INVENTION THE EFFLUENT GAS STREAM IS INTIMATELY CONTACTED WITH THE HYDROCARBON FEED STREAM SO THAT THE FREE HALOGEN IS SELECTIVELY ABSORBED IN THE HYDROCARBON FEED STREAM, AND THE REMAINING EFFLUENT GAS STREAM IS VENTED FROM THE PROCESS. ANOTHER ASPECT OF THE INVENTION RELATES TO UTILIZING THE EFFLUENT GAS STREAM DIRECTLY FOR EFFECTING THE HALOGENATION REACTION, SEPARATING THE HYDROGEN HALIDE PRODUCED FROM THE OTHER GASES BY ABSORBING THE HYDROGEN HALIDE IN WATER AND VENTING THE OTHER GASES.
