A novel solid base with activated carbon as supporter and alkali and earth-alkali compounds as active components has been developed for removal of hydrogen sulfide from light oils. The experimental results indicated that the solid base has excellent adsorption capacity for hydrogen sulfide. In addition, an additive added to feedstock that can promote significantly the removal of hydrogen sulfide for the solid base was also developed. The adsorption capacity of the solid base for hydrogen sulfide was evaluated with dynamic testing. (C) 2004 Elsevier B.V. All rights reserved.
