Abstract
A sulfur breakthrough monitoring assembly for use in a fuel utilization system for detecting sulfur-containing compounds in desulfurized fuel, said monitoring assembly comprising: a heater for heating desulfurized fuel to a predetermined temperature, the predetermined temperature being between 450° C. and 600° C., a sulfur breakthrough detector adapted to receive heated fuel from the heater and including at least a reforming catalyst bed for reforming the heated fuel and a plurality of temperature sensors including a first temperature sensor for sensing temperature of the heated fuel before the fuel is conveyed through the reforming catalyst bed and a second temperature sensor for sensing temperature in the reforming catalyst bed, and a controller for determining whether concentration of the sulfur-containing compounds in the fuel exceeds a first predetermined concentration based on temperature outputs from the first and second temperature sensors.
