1. A process for converting gaseous alkanes to liquid hydrocarbons comprising:
reacting a gaseous feed having lower molecular weight alkanes with bromine vapor to form alkyl bromides and hydrobromic acid;
reacting said alkyl bromides in the presence of said hydrobromic acid and a synthetic crystalline alumino-silicate catalyst and at a temperature sufficient to form higher molecular weight hydrocarbons and additional hydrobromic acid; and
removing said hydrobromic acid and said additional hydrobromic acid from said higher molecular weight hydrocarbons by reacting said hydrobromic acid and said additional hydrobromic acid with a metal oxide to form a metal bromide and steam.
