Abstract
Desulfurization of fuel is crucial in meeting environmental regulations in
reducing the sulfur content to minimize air pollution and protect human health.
Adsorptive desulfurization (ads) has emerged as a viable and efficient method for
sulfur compounds removal from diesel fuel. This method requires the ability of
adsorbents, such as activated carbon (acs) to selectively capture sulfur-containing
compounds. Activated carbons was produced from glycerin pitch, a natural resource
and industrial waste material, through the wet impregnation method employing
activating agents, namely phosphoric acid (h3po4), and ferum nitrate (fe(no3)3.9
h2o). The primary aim of this study is to emphasize the potential of glycerin pitch
activated carbon as an efficient and eco-friendly material means to attain ultra-low
sulfur fuel standards. The prepared activated carbons were characterized by x-ray
diffraction (xrd), nitrogen absorption analysis (na), field emission scanning
electron microscopy-energy dispersion x-ray (fesem and edx), fourier transform
infrared spectroscopy (ftir), thermogravimetric analysis (tga). Acs impregnated
with phosphoric acid have exceptionally high surface area (860 m2/g) and porous
structure (0.4012 cm3/g) which provides ample sites for adsorption of sulfur
compounds such as dibenzothiophene (dbt).
