    • This invention relates to a method for producing hydrocarbons with the simultaneous preparation of hydrogen in the reaction with iodine. Aliphatic saturated hydrocarbons, especially methane or ethane, are reacted with iodine, this reaction being conducted preferably in the presence of a catalyst, preferably at a temperature of 400-1200 DEG C, with the iodine/hydrocarbon molar ratio of 0,1 to 4,0, preferably with bromine addition, preferably by activation using a method of electric discharges and/or activation employing a method of electromagnetic radiation. After the reaction of hydrocarbons with iodine, hydrogen iodide and unreacted iodine are isolated from the mixture of hydrocarbons, said hydrogen iodide is decomposed into iodine and hydrogen, said iodine being recycled to the process, if need be, or hydrogen and hydrocarbons are separated and the reaction residue can be recycled to the process. In an optional solution, unsaturated hydrocarbons having a lower atomic ratio of carbon to hydrogen are used thus obtaining hydrocarbons of a larger carbon/hydrogen atomic ratio.
    • 本发明涉及在与碘反应中同时制备氢气的方法。 脂肪族饱和烃,特别是甲烷或乙烷与碘反应,该反应优选在催化剂存在下进行,优选在400-1200℃的温度下进行,碘/烃摩尔比为0.1至4 优选通过使用使用电磁辐射的方法的放电和/或激活的方法进行激活来优选加入溴。 在烃与碘反应后,从烃的混合物中分离碘化氢和未反应的碘,所述碘化氢分解成碘和氢,如果需要,则将碘回收到该方法中,或者氢和烃分离, 反应残余物可以循环使用。 因此,在任选的溶液中,使用碳 - 氢原子比低的不饱和烃,从而得到碳/氢原子比较大的烃。

    • The present invention provides an efficient process for the production of ethylene or a mixture of ethylene and vinyl chloride, in which some 1,2-dichloroethane (EDC) may also be produced, by reacting chlorine with ethane. The process is characterized by a conversion of ethane per pass through the reactor of at least about 50 %, and a combined molar yield of ethylene and vinyl chloride of at least about 80 % based on the ethane consumed. In accordance with this invention, there is provided a process for preparing ethylene or a mixture of ethylene and vinyl chloride by the reaction of ethane and chlorine which comprise: a) providing a stream of ethane feed gas and a stream of chlorine feed gas; b) preheating either said ethane stream only or both said ethane and chlorine streams; c) thoroughly mixing said ethane and chlorine feed gases within about one second and at a molar ratio of ethane to chlorine of at least about 0.9:1.0; d) said preheating being sufficient to enable the resultant mixture to have a temperature above the free radical formation temperature for chlorine; and e) permitting said ethane and chlorine in said mixture to react so that the reacted mixture has a temperature between about 600 DEG C and 800 DEG C; whereby the combined molar yield of ethylene and vinyl chloride is at least about 80 % of the ethane reacted.
    • 本发明提供了生产乙烯或乙烯和氯乙烯的混合物的有效方法,其中也可以通过使氯与乙烷反应来制备一些1,2-二氯乙烷(EDC)。 该方法的特征在于每次穿过反应器的乙烷转化率为至少约50%,并且基于消耗的乙烷,乙烯和氯乙烯的组合摩尔产率为至少约80%。 根据本发明,提供了通过乙烷和氯的反应制备乙烯或乙烯和氯乙烯的混合物的方法,其包括:a)提供乙烷进料气体流和氯气进料气流; b)仅将所述乙烷流或所述乙烷和氯气流预热; c)将所述乙烷和氯气进料气体在约1秒钟内以至少约0.9:1.0的乙烷与氯气的摩尔比充分混合; d)所述预热足以使所得混合物具有高于氯的自由基形成温度的温度; 和e)允许所述混合物中的所述乙烷和氯反应,使得反应的混合物的温度在约600-800℃之间; 由此乙烯和氯乙烯的组合摩尔产率是反应的乙烷的至少约80%。
