Abstract

Methane condensation to higher hydrocarbons with a single-pass methane conversion of 30% and total carbon selectivity of 90% has been achieved in a system of two-stage serial reactors. Methane reacts with HBr and oxygen in the first catalyst bed at 660 °C to form CH3Br and CH2Br2, while CH3Br and CH2Br2 are converted to higher hydrocarbons in the second catalyst bed at 240 °C. A reusable sorption material MgO/SiO2 has been identified for the separation of HBr from H2O and olefins (performed at 200 °C), making the recovery of bromine and the purification of olefins feasible.
