It has been supposed that modification of the pore structure of catalysts can provoke oscillations in pores, leading to an acceleration of internal mass transfer and to an increase. in die overall reaction rate. The present paper deals with a confirmation of this theoretical conclusion. It shows that an unsophisticated change in the pore structure can intensify the process of 1-octene hydrogenation to n-octane on a Ni tablet catalyst up to three times. (C) 2004 Elsevier B.V.
