摘要： A combination downflow contaminant treatment and/or removal bed in combination with a radial flow bed of contaminant sensitive catalyst in a single reactor vessel eliminates unexpected deactivation of contaminant sensitive catalyst. The process of this invention also monitors the entrance of contaminants into the downflow contaminant treatment/removal bed to measure total contaminant loading to avoid unnecessary shut-downs of the reactor vessel during temporary contaminant loadings. This invention is particularly useful for highly sulfur sensitive reforming catalysts that are used in combination with a sulfur sorbent for removal of the sulfur contaminants.
