Prediction of Pd/C catalyst deactivation rate and assessment of optimal operating conditions of industrial hydropurification process

One of the key concerns of the purification section of a purified terephthalic acid (PTA) production plant is the deactivation of palladium supported on carbon (Pd/C) catalyst. In this work, the deactivation rate model of 0.5 wt % Pd/C catalyst has been developed considering temperature, active surf...
