Disclosed is a process for converting gaseous alkanes to olefins 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 olefins and additional hydrobromic acid; and contacting said hydrobromic acid, said additional hydrobromic acid, and said olefins with water to remove said hydrobromic acid and said additional hydrobromic acid from said olefins.
