Claim Text:
1. A method of preparing a catalyst tube for executing catalytic processing of a material through the tube, in parallel with one or more other catalyst tubes, the method comprising: providing an empty catalyst tube; inspecting the tube interior via video to determine whether closer scanning of the tube is to be performed; detail scanning the tube interior to identify one or more dirt or contamination deposits for removal if such inspection reveals that scanning necessary; cleaning the tube inside wall if the step of detail scanning reveals deposits to be removed from the tube inside wall; measuring a pressure drop through the tube; filling the catalyst tube with catalyst and again measuring the pressure drop through the tube; comparing the last measured pressure drop to an average pressure drop taken with respect to the catalyst tube and the one or more other catalyst tubes; and if the pressure drop for the catalyst tube is within a predetermined variance of the average, identifying the catalyst tube as suitable for use.
