PROCESSES FOR PRODUCING HIGHER HYDROCARBONS FROM METHANE ANDBROMINE

摘要

Processes for producing C2 + hydrocarbons are provided. Such processes us e 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 metha ne; (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 leas t about 315° C to produce Br2; and (d) using at least some of the produced B r2 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 recovere d from (c) and used to provide at least some of the heating in (a), (b), or both.
