Some of these factors are elaborated further below. It should be noted that conventional approaches for fuel desulfurization in response to the 1993 diesel fuel sulfur regulation (500ppmw sulfur) in the U.S. were to increase process severity of HDS, increase catalysts-to-fuel ratio, increase residence time, and enhance...
