Abstract

Methanol has been successfully synthesised from biomass pyrolysis syngas, inheriting the unconventional composition, i.e., H2-deficiency, high CO2 concentration, and CH4 impurity, using Cu/ZnO-based catalysts. The results of this study offer novel insights into the challenges of producing methanol from unconventional syngas and future opportunities to develop a robust catalyst that can handle the unique composition of low-quality syngas. Catalyst composition, catalyst deactivation mechanism, and optimising operating conditions are the valuable insights revealed in this study, which can be used as a foundation for commercial scale methanol plants using unconventional syngas as the feedstock.
