The construction of the first high-pressure liquid-phase flow microreactor has been completed, and kinetic studies of reaction of dibenzothiophene have been started. Understanding of catalytic hydrodesulfurization and catalyst decay has been advanced by examination of the reaction rate of thiophene, tetrahydrothiophene, and butanethiol on Harshaw 0402T catalyst. Two batch autoclave reactors have been completely assembled behind appropriate safety barricades; satisfactory operation has been demonstrated; and quinoline hydrodenitrogenation studies are underway to demonstrate operating procedures providing quantitative, reproducible data. Quinoline rapidly hydrogenates to tetrahydroquinoline; the two compounds appear to be in thermodynamic equilibrium. The tetrahydroquinoline apparently undergoes slow hydrogenolysis of the nitrogen-containing ring giving n-propylaniline as an identified long-lived product. The reaction engineering of the pulsed microreactor system has been developed and compared to some laboratory data. The moments of the inlet and exit pulses show substantial effects from product adsorption.
