Catalytic hydrotreating of bio-oil and evaluation of main noxious emissions of gaseous phase

Abstract Bio-oil produced from biomass pyrolysis has the potential to become an alternative renewable fuel. However due to the high content of oxygenated compounds is unsuitable as transportation fuel. The objective of this work is to evaluate the catalytic activity of CoMo /γ-Al2O3-HMS in the hydro...
