Organonitrogen, organosulfur compounds

The removal of sulfur from organosulfur compounds is an important catalytic reaction during petroleum refining [198, 199]. A test reaction for this process is the hydrodesulfurization of thiophene to butenes. Describe the process [209]. The removal of nitrogen from organonitrogen compounds is equally important. Describe the process [210]. 

It is the need for improvements in the HDS and HDN processes or the development of new methods for the removal of sulfur and nitrogen from fuels that has attracted the interest of inorganic and organometallic chemists. Their investigations have been directed toward understanding how organosulfur and organonitrogen compounds bind in transition metal complexes as models for their adsorption on active sites of catalyst surfaces such studies have also provided... 

The model assumes that the organosulfur, organonitrogen, aromatic, and olefin compounds, as well as the liquid hydrocarbons, are nonvolatile therefore, the unsteady state mass balance for the liquid compounds is...
