H2S removal from sour liquefied petroleum gas using jordanian oil shale ash

Abstract

Oil shale ash was used to adsorb hydrogen sulfide from liquefied petroleum gas (LPG). Fixed mass of ash of particle size 500-710 μm showed a sorption capacity of 30 mg H2S per liter of LPG and one gram of ash from 150 ml LPG containing 467 ppm H2S. This value increased with increasing the volume of spiked gas and decreasing the particle size of the ash, while it decreased with increasing bed temperature. Ash samples did not adsorb hydrocarbons. © 2007 Estonian Academy Publishers.
