Abstract

See full text

Embodiments disclose a process for converting gaseous alkanes to higher molecular weight hydrocarbons, olefins or mixtures thereofs wherein a gaseous feed containing alkanes may be reacted with a dry bromine vapor to form alkyl bromides and hydrobromic acid vapor. The mixture of alkyl bromides and hydrobromic acid then may be reacted over a synthetic crystalline alumino-silicate catalyst, such as a ZSM-5 or an X or Y type zeolite, at a temperature of from about 250° C. to about 500° C. so as to form hydrobromic acid vapor and higher molecular weight hydrocarbons, olefins or mixtures thereof. Various methods are disclosed to remove the hydrobromic acid vapor from the higher molecular weight hydrocarbons, olefins or mixtures thereof and to generate bromine from the hydrobromic acid for use in the process.
