Surface chemistry analysis of acidified and nickel impregnated carbon for desulfurization of fuels

Abstract

Abstract Emission norms tend to reduce sulfur content in transport fuels to 10ppm. Considering this new method like adsorptive desulfurization are widely researched. The main motive in adsorptive desulfurization is to selectively adsorb Dibenzothiophene (DBT) and 4,6-DimethylDBT. Considering this adsorbent with nickel impregnation and acidic surface functionalities were developed. Topographical and surface chemical features were studied of developed carbon adsorbents. Presence of carboxylic surface functionalities and reduced solid nickel was confirmed on adsorbents surfaces. In addition to this formation of nickel complexes due to neutralization of nickel ion and carboxylic groups was confirmed. This type of adsorbents can act as potential adsorbents for adsorption of DBT and 4,6-dimethyl DBT.
