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 high content of oxygenated compounds is unsuitable as transportation The objective this work evaluate catalytic activity CoMo /γ-Al 2 O 3 -HMS in hydrotreating process bio-oil. prepared catalyst was characterized by different techniques (X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron (XPS)) analysis. experiments were carried out a flow fixed-bed reactor at temperature range 250–320 °C, pressure between 20–40 bar, LHSV h -1 . results showed that mild conditions 320 °C 40 very active leading decrease total acid number hydrotreated bio-oil with almost 89% conversion 87.23%. In addition, order harmful emissions resulted combustion gaseous phase obtained chemical modelling algorithm developed.
