The utilisation of alternative feedstocks for everyday chemicals is of key industrial importance as we move towards net zero and beyond. Methanol derived from various carbon sources, such as CO 2 , biomass, and biogas, is already of considerable economic interest. The methanol-to-hydrocarbon (MTH) process is poised to offer a pathway to numerous commercially and industrially significant chemicals. The first step in the MTH process, the dehydration of methanol to dimethyl ether (DME), is of particular interest as DME is an important solvent and the starting material for many other products.
