BrOx cycle: A novel process for CO2-free energy production from natural gas

Thermodynamic and kinetic simulations have been performed that show the feasibility of the BrOx cycle. The influence of temperature, residence time and feed composition on methane bromination reaction was studied and indicates that carbon formation starts at temperatures as low as 500 °C for excess methane, while temperatures over 750 °C are necessary in order to achieve noticeable carbon formation when working with excess bromine. The composition of the carbon produced has been determined and the mass fraction of bromine-containing by-products has been found to decrease with increasing reaction temperatures.
