Rice husk activated carbon (RHAC) and coconut shell activated carbon (CSAC) were tested to remove sulfur compounds of benzothiophene (BT) types and dibenzothiophene (DBT) types from commercial kerosene. The adsorption isotherms of RHAC and CSAC for those sulfur compounds were obtained in batch-mode. Fixed-bed flowing tests were also conducted, providing their breakthrough curves of BT types and DBT types. It was shown that RHAC was effective to remove BT types, while CSAC was good at removing DBT types. The porosity and surface chemistry of RHAC and CSAC were studied in relation to their adsorptive removal performances of BT types and DBT types.
