Catalytic Pyrolysis of Biomass Using Biochar and MgFe2O4-Modified Biochar in a Continuous Auger Reactor
Short Introductive summary
This study explores the application of biochar-based catalysts, including magnesium ferrite (MgFe2O4)-modified biochar, to improve the catalytic pyrolysis of biomass in a continuous Auger reactor. Three pine bark–derived catalysts (thermally activated biochar, steam-activated biochar, and MgFe2O4-impregnated steam-activated biochar) were investigated for their effectiveness in enhancing bio-oil quality and gas composition. The MgFe2O4-modified biochar exhibited the highest catalytic stability and influence, achieving a 55.6% reduction in water content in the organic bio-oil fraction, a 19.3% increase in heating value, and a marked rise in hydrogen concentration in the product gas (up 5,31% to 18.26%). These findings highlight the potential of MgFe2O4-modified biochar as a cost-effective and efficient bifunctional catalyst for simultaneously upgrading bio-oil and improving gas quality in biomass pyrolysis.
