This standard specifies a method for the determination of chlorine content in reforming catalysts using the potential Titrimetric method. It is suitable for fresh, regenerated and pending reforming catalysts with a determination range of 0.60% to 1.80%. The document lists the necessary normative reference documents and defining terms. The method outline includes the extraction of the sample with a hot alkali solution and then the determination of chloride ion content using the potential Titrimetric method. Users are cautioned to take appropriate safety measures during use.
