What are the measures to prevent deactivation of the reforming catalyst?

At present, advanced DCS control systems are able to optimize various conversion hydrogen production parameters on-line, and each advanced instrumentation system has formulated multiple target simulation optimization schemes, which take into full consideration the requirements of the conversion catalyst on air velocity, water-carbon ratio and temperature during the optimization process, and can achieve the optimum of the system on the basis of guaranteeing the production and quality of hydrogen gas. These are only external factors. If we really want to prolong the service life of the catalyst (or avoid unplanned stops due to inactivation of the reforming catalyst), it is necessary for the technicians and operators to take the following measures:
1) Load the catalyst into each tube carefully and evenly, and ensure that the loading quality and loading technique are within the required range.
2) Avoid unplanned stops as much as possible.
3) Eliminate water in the steam inlet of the reforming inlet.
4) Select feed material with small C/H, light component and no poison.
5) Reasonable control of water-carbon ratio, feed air velocity and furnace temperature and maintain relatively stable system pressure.
6) Instrument malfunctions should be detected and dealt with appropriately.
