Abstract
A bottom vessel head mounted tube within a tube assembly is used to retrieve particulate matter from a fixed bed reactor. Particulate matter enters the device through coinciding inlet ports in the tubes and flows by gravity to the bottom of the inner tube. By shifting the alignment of the inlet ports, flow is stopped and the catalyst sample flows by gravity into a valved receiver which is depressurized before catalyst is recovered. The device samples catalyst at one elevation.
