In Situ Conditioning of CO2-Rich Syngas during the Synthesis of Methanol

The synthesis of methanol from biomass-derived syngas can be challenging because the high CO2 content in bio-syngas, resulting lower kinetics and higher catalyst deactivation. This work explores situ pre-treatment a CO2-rich with CO2/CO ratio equal to 1.9 through reverse-water gas shift reaction aim adjusting this more favorable one for Cu-based catalysts. Both reactions take place two catalytic beds placed same reactor, thus intensifying process. water produced during conditioning is removed by means sorbent zeolite prevent deactivation equilibrium towards formation. combination shifting sorption strategies lead productivities bed and, under certain conditions, productions.
