Abstract

A tool that can be used to load catalyst into a chemical reactor. In a preferred embodiment, the tool may also be used to measure the outage in the reactor tube. Also in a preferred embodiment, the tool provides a way to prevent dust from accumulating on the upper tube sheet of the reactor while loading catalyst into the reactor tubes.

Claims (6)

1. A method for loading a chemical reactor tube with catalyst, comprising the steps of:

inserting a loading sleeve into an open top of the reactor tube; then

inserting catalyst through said loading sleeve into said reactor tube; then

removing the loading sleeve from the reactor tube; then

re-inserting the loading sleeve into the reactor tube until the loading sleeve contacts the catalyst; and then

reading a marking on the loading sleeve which is visible above the reactor tube when the loading sleeve has been re-inserted in order to determine whether the outage above the catalyst is within a desired range.
