Zeolites are popular catalysts for converting biomass to renewable chemicals. Their applications span from the liquid phase conversion of carbohydrate-derived compounds to the gas-phase pyrolysis of raw biomass. However, the shift from petroleum to biomass as a feedstock generates new challenges for the design of zeolite-based catalysts. Conventional zeolites such as ZSM-5 and Beta are unstable in hot liquid water and deactivate through leaching and/or collapse of their crystal structure. Similar deactivation processes take place during fast pyrolysis as a result of the high temperatures and fast heating rates that are typically required to achieve high yields. Here, we will share key considerations for enhancing the performance of zeolite catalysts and for improving their stability for both liquid- and gas-phase biomass conversion reactions.
