A flow microreactor has been designed for study of kinetics of hydroprocessing reactions and the accompanying catalyst aging. It operates at temperatures up to 450 °C and pressures up to 300 atm. Liquid reactant (containing dissolved hydrogen) can be fed steadily at 0.5 to 600 cm3/h or as pulses injected into a stream of liquid carrier. The design is specified, and the operation is illustrated by conversion data for hydrodesulfurization of dibenzothiophene and of 4-methyldibenzothiophene catalyzed by sulfided "cobalt molybdate" at 300 °C and 104 atm and for hydrodenitrogenation of quinoline catalyzed by sulfided "nickel molybdate" at 342 °C and 165 atm.
