Abstract
Methane activation via bromination can be a feasible route with selective synthesis of mono-bromomethane. It is known that the condensation of brominated products into higher hydrocarbons can result in coking and deactivation in the presence of di-bromomethane. In this study, selective production of methyl bromide was investigated over sulfated ZrO 2 included SBA-15 structures. It was observed that the higher the ZrO 2 amounts the higher the conversion, while the catalyst remained >99% selective for the monobrominated methane. Over 25 mol.% ZrO 2 included SBA-15 catalyst with a BET surface area of 246 m 2/g, methane was brominated with 69% conversion at 340 °C and only CH 3Br was selectively produced.
