Groundnut-shell derived oxygen enriched mesoporous carbon adsorbent for removal of thiophenic sulfur compounds.

In this work, groundnut shell-derived mesoporous carbons, synthesized by one-step carbonization at different temperatures in presence of potassium hydroxide, were used for desulfurization studies involving dibenzothiophene, benzothiophene and thiophene. The pore formation and corresponding surface area of synthesized mesoporous carbon was governed by carbonization temperature as it increased from 600 to 900 °C. The carbon synthesized at carbonization temperature of 800 °C, that is GN-800, showed highest surface area (1192 m/g) and pore volume (0.
