Abstract
The present invention relates to a process for the substantial reduction of hydrogen sulfide formation during retorting of oil shale by previously treating the oil shale under mild oxidative conditions to passivate the pyrite present in the oil shale. The oxidation of the oil shale under mild oxidative conditions results in the reduction of hydrogen sulfide formation during retorting without a decrease in the amount of oil produced.
