Abstract

The pressure drop across a laboratory-scale catalyst packed bed with mechanical failure of catalyst pellets has been examined. It was found that the increased pressure drop can be described by a simplified model deduced from Ergun's equation. The pressure drop is determined mainly by the term of viscous energy loss.
