Abstract
An improved method of hydrocarbon hydrotreating is disclosed wherein the activity of a hydrotreating catalyst is determined prior to the catalyst being used to promote hydrocarbon hydrotreating. The catalytic activity of such a catalyst is determined by comparing a parameter involving the relative reflectance of the catalyst relative to the relative reflectance of a standard catalyst having acceptable activity. When it is determined that a given catalyst has catalytic activity at least essentially equal to that of the standard catalyst, the catalyst may be used to promote hydrocarbon hydrotreating thus providing an improved method of hydrocarbon hydrotreating.
