Abstract
A back-end guard bed is located downstream of and in series with a nickel catalyst-containing sulfur trap to remove the organosulfur-nickel complex formed in the nickel catalyst-containing sulfur trap and passed along with the product therefrom during periods of hydrofiner upset, or such other periods when sulfur concentration, flow rate and operating temperature of the feed passed from the hydrofiner through the nickel catalyst-containing sulfur trap forms the organosulfur-nickel complex.
