Abstract. The rate constants of all reaction steps in the hydrodesulfurization (HDS) of dibenzothiophene (DBT), 4,6- dimethyldibenzothiophene (DMDBT), and their tetra- and hexahydro intermediates TH(DM)DBT and HH(DM)DBT over Ni–MoS2/y-Al2O3 were determined. DBT, THDBT, DMDBT, and THDMDBT underwent desulfurization by hydrogenolysis of both C–S bonds, while HHDBT and HHDMDBT underwent des…

Synthesis and characterization of mesoporous mordenite
Abstract. Three methods were investigated to synthesize mesoporous mordenite. XRD, N2 physisorption, SEM, and TEM showed that the mordenite obtained by acid leaching followed by base leaching of a conventional mordenite is a crystalline mesoporous material with MOR framework. The higher diffusivity of toluene indicated that mesopores benefited molecule transport through the zeolite crystal.…

Hydrodesulfurization of dibenzothiophene and its hydrogenated intermediates o…
Abstract. Two intermediates of dibenzothiophene (DBT)—tetrahydro-DBT (THDBT) and hexahydro-DBT (HHDBT)— were synthesized, and their hydrodesulfurization (HDS) mechanism was investigated over Mo/γ -Al2O3 at 300–340 ◦C and 5 MPa in the absence and presence of H2S and 2-methylpiperidine. The rate constants of all steps in the kinetic network of the HDS of DBT were measured. THDBT underwe…
