Performance of a process, for catalytic conversion of a substantially contaminant-free hydrocarbon feed with a comtaminant-sensitive catalyst using a conversion system having equipment contaminated through contact with a contaminant-containing prior feed, is substantially improved by using a sacrificial particulate bed to remove contaminants such as sulfur from the contaminated conversion system prior to loading the contaminant-sensitive catalyst. After contaminant removal is substantially complete, the sacrificial particulate bed is replaced with the contaminant sensitive catalyst and the contaminant-free feed is charged to the conversion system at hydrocarbon conversion conditions. |
