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).

Mo–Ni/Al-SBA-15 (Sulfide) Catalysts for Hydrodenitrogenation: Effect of Si/Al Ratio on Catalytic Activity
C. Suresh,D. Santhanaraj,M. Gurulakshmi,G. Deepa,M. Selvaraj,N. R. Sasi Rekha,Kannan Shanthi +6 more
TL;DR: In this paper, Mo-Ni/Al-SBA-15(10) was used for Methylcyclohexylamine conversion to hydrocarbons and the observed trend of activity is correlated with the aluminum content, and it was concluded that the variation in Si/Al ratio remarkably affects the hydrodenitrogenation ability of Al-Sba-15 supported Mo−Ni catalysts.
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
Mesoporous H-AlMCM-41 supported NiO-MoO3 catalysts for hydrodenitrogenation of o-toluidine: I. Effect of MoO3 loading
TL;DR: The mesoporous molecular sieve, H-AlMCM-41, was synthesized hydrothermally and used as support for the preparation of series of sequentially impregnated NiO-MoO 3 catalysts as discussed by the authors.
