Abstract
This invention provides a method for reducing the level of thiophenic sulfur compounds in a heavy carbonaceous oil feed which involves contacting the oil feed with a C.sub.1 -C.sub.4 alkanol in the presence of a non-acidic zeolite catalyst. The reaction equilibrium in the process favors the displacement of thiophene sulfur atoms by oxygen atoms.
