Hydrotreating reactions of tall oils over commercial NiMo catalyst
Catalytic hydrotreating is an attractive method for upgrading bio-derived oils into renewable feedstocks with less oxygen content, suitable for producing valuable hydrocarbons through various petro-refinery processes. This study evaluates the catalytic activity of a commercial alumina (Al2O3) supported NiMo catalyst for hydrotreating tall oil feeds such as crude tall oil (CTO), distilled tall o...
متن کاملHydrotreating of tall oils on a sulfided NiMo catalyst for the production of base-chemicals in steam crackers
This research thesis validates the potential of tall oil as a renewable feedstock for the production of base-chemicals, especially olefins, as conceived in the thermo-chemical bio-refinery concept. The focus was on the use of hydrotreating and steam cracking technologies with different tall oil feedstocks. Particular advances were accomplished in terms of technology development for high yield o...
متن کاملSimultaneous Hydrogenation of Multiring Aromatic Compounds over NiMo Catalyst
Hydrogenation of six model feeds containing three-, two-, and one-ring aromatic compounds was investigated to gain insights into the aromatic hydrogenation reaction chemistry over a commercial NiMo catalyst under practical reaction conditions. The hydrogenation reactivity of the aromatic compounds followed the following order: phenanthrene ∼ two-ring aromatics . one-ring aromatic. Comparison wi...
متن کاملInhibition of the Hydrogenation and Hydrodesulfurization Reactions by Nitrogen Compounds over NiMo/Al2O3
The inhibiting effect of nitrogen compounds on the hydrogenation of aromatic compounds and on the hydrodesulphurization (HDS) of dibenzothiophene (DBT) and 4,6-dimethyl dibenzothiophene (4,6 DMDBT), has been systematically investigated over a commercial NiMo hydrotreating catalyst. Amongst the different nitrogen compounds considered, interestingly ammonia was found to have the strongest inhibit...
متن کاملHydrocracking of Jatropha Oil over non-sulfided PTA-NiMo/ZSM-5 Catalyst
The PTA-NiMo/ZSM-5 catalyst impregnated with phosphotungstic acid (PTA) was designed for the transformation of Jatropha oil into benzene, toluene, and xylenes (BTX) aromatics. The produced catalyst was characterized by N2 adsorption-desorption, powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), and the temperature-programmed desorption of...
