The intrinsic effect of co-feeding water on the formation of active/deactivating species in the methanol-to-hydrocarbons reaction on ZSM-5 zeolite
José Valecillos, Gorka Elordi, Andrés T. Aguayo, Pedro Castaño
Abstract
Water is formed and added in the conversion of methanol to hydrocarbons, slowing down both the reaction and deactivation rates. The retained species that are reaction intermediates and coke precursors are swept/desorbed, particularly those on silanol sites.
