摘要

Waste tires are one potential source of alternative energy because of their long chain hydrocarbon with a high calorific heating value. However, the pyrolysis oil that is derived from waste tires is not appropriate for direct use in a combustion process due to its high sulfur content. Therefore, the oxidative desulfurization (ODS) process was evaluated for its ability to reduce the sulfur content of the naphtha fraction dis-tillated from light oil derived from waste tire pyrolysis. The addition of formic acid to pH of 4.0 in the presence of 25 vol.% hydrogen peroxide (H_2O_2) and tire pyrolysis char enhanced the level of sulfur removal to ca. 70% due to the simultaneous adsorption and oxidation of sulfurous compounds on the surface of the pyrolysis char. The chemical treatment to form surface-modified char promoted the benefit for ODS process in the presence of formic acid (pH 4) and H_2O_2 (25 vol.%) by increasing the sulfur reduction in the pyrolysis naphtha up to 75%.
