Catalyst Deactivation & EOR Prediction
Linear WABT deactivation rate, end-of-run prediction, and cycle-length assessment for hydroprocessing fixed-bed catalysts.
Method: Linear extrapolation of normalized WABT — deactivation rate = (WABTcurrent − WABTSOR) / days on stream. EOR date projected from remaining available ΔT at constant rate. Always use normalized WABT (constant feed rate, feed quality, product target) or the deactivation rate will be masked by operating changes.
