HYCO plants utilise a number of catalyst types and catalytic technologies to produce hydrogen, carbon monoxide, or mixtures thereof.
These catalysts are comprised of various chemical compounds across a number of support materials and structures, and reaction occurs in tubular, fixed bed, or modular reactors. Most of these catalysts are replaced periodically.
There are safety hazards involved in the storage, loading, unloading, and disposal of these catalysts. These hazards include the handling of self-heating or potentially pyrophoric materials and the presence of toxic metals (for example, nickel, chromium, etc.), toxic metal carbonyls, and hexavalent chromium. There are also hazards associated with verification of uniformity of catalyst installation, including managing the differential pressure measurements taken during loading of reformer tubes.
This publication covers the safety aspects of all catalysts and chemisorbents such as zinc oxide used in HYCO facilities
