Effects of the Support on the Performance and Promotion of (Ni)MoS2 Catalysts for Simultaneous Hydrodenitrogenation and Hydrodesulfurization
Oliver Y. Gutiérrez,Srujan Singh,Eva Schachtl,Jeongnam Kim,Elena Kondratieva,Jennifer Hein,Johannes A. Lercher +6 more
TL;DR: In this article, Ni-promoted MoS2 catalysts supported on γ-Al2O3, siliceous SBA-15, and Zr- and Ti-modified Sba-15 were explored for the simultaneous hydrodesulfurization (HDS) of dibenzothiophene (DBT) and hydrodenitrogenation (HDN) of o-propylaniline (OPA).
Journal ArticleDOI
Selective poisoning of the direct denitrogenation route in o-propylaniline HDN by DBT on Mo and NiMo/γ-Al2O3 sulfide catalysts
TL;DR: In this article, the authors show that the presence of Dibenzothiophene (DBT) decreases the DDN rate, while increasing the electron density at the brim sites due to the electron pair donor properties of DBT and biphenyl.
Journal ArticleDOI
Ring opening of 1,2,3,4-tetrahydroquinoline and decahydroquinoline on MoS2/γ-Al2O3 and Ni–MoS2/γ-Al2O3
TL;DR: In this article, the rate of C(sp(3))-N bond cleavage was investigated in decahydroquinoline and quinoline on MoS2/gamma-Al2O3 and Ni-MoS2 /gamma al 2O3 via two routes.
Journal ArticleDOI
Understanding Ni Promotion of MoS2/γ‐Al2O3 and its Implications for the Hydrogenation of Phenanthrene
Eva Schachtl,Lei Zhong,Elena Kondratieva,Jennifer Hein,Oliver Y. Gutiérrez,Andreas Jentys,Johannes A. Lercher +6 more
TL;DR: In this paper, the chemical composition and structure of NiMo sulfides supported on γ-Al2O3 and its properties for hydrogenation of polyaromatic compounds are explored.
Journal ArticleDOI
Simultaneous hydrodenitrogenation and hydrodesulfurization on unsupported Ni-Mo-W sulfides
Sylvia Albersberger,Jennifer Hein,Moritz W. Schreiber,Santiago Guerra,Jinyi Han,Oliver Y. Gutiérrez,Johannes A. Lercher +6 more
TL;DR: In this article, the catalytic properties of unsupported Ni-Mo-W sulfides (composites of NiMo(W)S 2 mixed sulfides and Ni 3 S 2 ) obtained from precursors synthesized via co-precipitation, hydrothermal, and thiosalt decomposition were explored for hydrodenitrogenation (HDN) of o -propylaniline or quinoline in presence and absence of dibenzothiophene undergoing hydrodesulfurization (HDS).
