Scope
Main technical content: This document specifies the technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage of regenerated tungsten-molybdenum hydrogenation catalysts. This document is applicable to regenerated tungsten-molybdenum hydrogenation catalysts made from deactivated catalysts containing nickel-molybdenum (tungsten), cobalt-molybdenum (tungsten), and tungsten-molybdenum-nickel that are replaced from petroleum refining units. The catalysts are restored to their original activity by air combustion, and the regenerated tungsten-molybdenum hydrogenation catalysts are obtained in this way.
