Abstract
A process for the deep desulfurization of a heavy pyrolysis gasoline to very low levels of organic sulfur, e.g., 30 ppmv or less, with minimal octane number loss through aromatics saturation. The deep desulfurization is accomplished by contacting the heavy pyrolysis gasoline feedstock, partially in liquid and partially in gaseous phase, with a hydrogen treat gas containing a minimum HS level in the presence of a hydrogenation catalyst in a one or two reactor system operated in trickle flow, using a low temperature, moderate pressure operating condition.
