Abstract
A method of reducing the sulfur and nitrogen content of a hydrocarbon, specifically, a liquid or gaseous phase hydrocarbon which comprises contacting the hydrocarbon with nahcolite in an amount effective to remove sulfur and nitrogen compounds from the hydrocarbon. The nahcolite containing combined sulfur and nitrogen can be removed from the hydrocarbon, producing a hydrocarbon having a reduced sulfur and nitrogen content. The method is particularly applicable to the reduction of the sulfur and nitrogen content in shale oil by contacting shale oil and nahcolite in a shale oil retort or process.
