Simultaneous Adsorptive Desulfurization and Denitrogenation by Zinc Loaded Activated Carbon: Optimization of Parameters

摘要

The authors focus on simultaneous removal of the dibenzothiophene and quinoline by using the zinc impregnated granular activated carbon (Zn-GAC). Parameters such as adsorbent dose, initial adsorbent concentration, temperature, and contact time were optimized for the simultaneous adsorption onto Zn-GAC using the Taguchi's experimental design methodology. Adsorption of quinoline was found to be more as compared to dibenzothiophene. Overall adsorptive behavior of dibenzothiophene and quinoline was antagonistic in nature. Analysis of variance was used to maximize simultaneous desulfurization and denitrogenation, which has been validated by performing confirmation experiments.
