A process for the catalytic removal of sulfur from a hydrocarbon stream such as gasoline comprising an organo-sulfur compound such as a mercaptan or thiol. The catalyst is a silica based zeolite such as ZSM-5. The process is preferably performed in a downer reactor with a residence time of between 7 and 30 seconds and a volumetric particle concentration of between 15 and 40%. Preferably, substantially all of the sulfur that is removed from the organo-sulfur compound is in the form of hydrogen sulfide.
