ABSTRACT:
A system for measuring crush properties of a catalyst bed includes a catalyst bed container which includes at least one deformable wall around and adjacent to a catalyst bed. The catalyst bed container is enclosed within a pressure vessel. The pressure vessel is coupled to a pressure gauge and to a pump which acts to introduce measured quantities of an incompressible fluid such as water into the pressure vessel around the catalyst container. A pressure gauge is provided for measuring the pressure of the fluid within the pressure vessel. Two conduits extend from spaced positions within the catalyst vessel to the exterior of the pressure vessel, in order to create an air flow across a portion of the catalyst bed. Two spaced pressure taps also extend from locations within the catalyst vessel outside of the pressure vessel, and are coupled to a pressure sensor such as a manometer, for measuring the differential pressure between these two pressure taps. By measuring the volume of water introduced into the pressure vessel and the pressure drop across the catalyst bed within the catalyst vessel, each as a function of the pressure of the water in the pressure vessel, the crush properties and the flow resistance properties of the catalyst can be measured in a simple and efficient manner.
