In order to investigate the relation between hydrodemetalation of heavy oil and the catalyst pellet size, reactions were carried out by a batch reactor using four kinds of commercial HDS catalysts with different pore size distributions. In the vicinity of 1-mm catalyst pellet size, demetalation activity was significantly affected by pellet size. However, as the pellet size decreased, the activity reached a constant level. These results were analyzed by a simple equation including the Thiele modulus, and it was revealed that the equation can be applied even to such complicated reactions as residue hydrodemetalation.
