Abstract
Methanol and/or dimethyl ether are manufactured from methane by mixing methane and bromine in a reactor to form methyl bromide and hydrogen bromide. The methyl bromide only or the methyl bromide and the hydrogen bromide are directed into contact with metal oxide to form methanol and/or dimethyl ether and a metal bromide. The metal bromide is oxidized to form original metal oxide catalyst and bromine, both of which are recycled.
