More Information
Summary:The present invention generally relates to processes for reducing the rate of pressure drop increase in a vessel used for hydrogenation of aldehydes to alcohols. In one embodiment, the process comprises replacing a first set of catalyst pellets with a second set of catalyst pellets, wherein the second set of catalyst pellets have a higher average aspect ratio than the first set of catalyst pellets, a different shape than the first set of catalyst pellets, or a combination thereof, and wherein a void fraction of the second set of catalyst pellets is greater than the void fraction of the first set of catalyst pellets, wherein a pressure drop rate increase of the vessel partially filled with the second set of catalyst pellets is less than a pressure drop rate increase of the vessel partially filled with the first set of catalyst pellets when operated under substantially similar conditions.
