Fig. 5. (a) Time-course variation of DBT conversion over 20 mg of the series of ATZ catalysts at 333 K; (b) time-course variation of DBT conversion with various Ti concentrations and (c) pseudo first-order rate constant for different concentrations of the ATZ-TEA catalyst at 333 K; (d) pseudo zero-order rate constant for different concentrations of TBHP; (e) time-course variation of DBT conversion at different reaction temperatures and (f) Arrhenius plot for the conversion of DBT over the 30 mg ATZ-TEA catalyst. Reaction conditions: 10 mL of 500 ppm model fuels, n(sulphide)/n(TBHP) = 0.5.
