A number of investigators have studied the kinetics of the metal removal rate over commercial CoMo/Al{sub 2}O{sub 3} catalysts with various crudes and resid feedstocks. The kinetic order of hydrodemetallization (HDM) with respect to the metal concentration has been reported as first order, fractional 1.5 order and second order. Hung and Wei have studied the kinetics of HDM in a batch reactor system over a non-sulfided commercial CoMo/Al{sub 2}O{sub 3} catalyst, using pure metal-porphyrin compounds. They reported that the HDM reaction order was close to 0.5 but varied with the operating temperature and pressure. Agrawal and Wei, in flow microreactor studies of the same compounds, observed first-order kinetics.
