Abstract
A process for producing an infusible and insoluble granular sulfurized material by reacting a petroleum heavy material and sulfur with stirring in the presence of a reaction medium and further in the presence of, if necessary, an infusible and insoluble solid material, and, further, a process for producing granular carbon comprising carbonizing the granular sulfurized material produced above or alternatively a process for producing granular activated carbon comprising carbonizing and activating the granular sulfurized material.
