Petroleum crudes, residual stocks, gas oils and the like which contain metals are pretreated with a sulfonating agent and the mixture separated into two fractions of which the lesser in volume has a greater concentration of metal and Conradson Carbon components. One or both of those fractions is mixed with a catalytically inert solid at high temperature to transfer metallic compounds and Conradson Carbon components to the solid for improvement of the fraction.
