    • Processes for producing C2+ hydrocarbons are provided. Such processes use Br2, HBr, and/or heat that are produced by such processes, thus providing commercially efficient processes. The process can comprise (a) producing HBr and methyl bromide using a bromine source and a gas stream comprising methane; (b) heating the methyl bromide in the presence of a catalyst to produce additional HBr and C2+ hydrocarbons; (c) combining at least some of the HBr and an oxygen source in the presence of a cerium-containing compound at least about 315° C. to produce Br2; and (d) using at least some of the produced Br2 from (c) as at least a portion of the bromine source in (a). Additionally, the additional HBr from (b) can be used in (c) and/or heat can be recovered from (c) and used to provide at least some of the heating in (a), (b), or both.
    • 提供了生产C2 +烃的方法。 这种方法使用通过这些方法生产的Br 2,HBr和/或热,从而提供商业上有效的方法。 该方法可以包括(a)使用溴源和包含甲烷的气流产生HBr和甲基溴; (b)在催化剂存在下加热甲基溴以产生额外的HBr和C2 +烃; (c)在至少约315℃的含铈化合物的存在下将至少一些HBr和氧源合并以产生Br 2; 和(d)使用来自(c)的所产生的Br 2中的至少一些作为(a)中的溴源的至少一部分。 另外,来自(b)的另外的HBr可以用于(c)中,和/或可以从(c)回收热量,并用于在(a),(b)或两者中提供至少一些加热。
