Abstract Ni‐MoS 2 /γ‐Al O 3 catalysts are commonly used in hydrotreating to enhance fossil fuel quality. The extensive research on these reveals a gap understanding the role of Ni, often underestimated as an inactive sulfide phase or just MoS promoter. In this work, we focused analyzing whether well‐dispersed supported nickel nanoparticles can be active hydrodesulfurization dibenzothiophene. We dispersed Ni by Strong Electrostatic Adsorption (SEA) method across four supports with different...
Abstract The mechanochemical synthesis of zeolites reduces the generation liquid residues and gaseous pollutants. Herein, MFI were synthesized by a seed‐assisted pathway. effect different variables, Na 2 O/SiO H molar ratios milling time speed, their interactions on physicochemical properties catalytic performance alkylation phenol with tert‐butyl alcohol studied. Results showed that ratio may direct to preferential production MOR instead MFI. Also, speed interaction, i. e., (milling...
Bio-oils obtained from rapid pyrolysis have emerged as a renewable energy source, but their high content of oxygenated molecules gives them unwanted properties for use fuels. Hydrodeoxygenation (HDO) is the process used to improve its quality and commonly studied with model such guaiacol. Bimetallic NiCu catalysts are highly active in hydrogenation reactions. However, published studies do not allow us conclude whether addition Cu produces same effect HDO For this reason, work we study...
To reduce pollution, sulfur, nitrogen, and other heteroatoms are removed from fuels by hydrotreatment (HDT). Conventional HDT catalysts based on Ni-MoS2 phases dispersed over -Al2O3. Despite the myriad of papers studying these catalysts, it is somehow surprising to learn that role Ni in not yet fully understood. Most literature considers either converted some form catalytically inactive nickel sulfide or mixes with MoS2 act as a strong catalytic promoter. In this work, we focused analyzing...
Technical catalysts are shaped as pellets, extrudates, beads, and monoliths. Most often, they composed of a mixture oxides used carriers for metallic phases. The latter usually incorporated by wet impregnation; method with strong environmental impact due to the production liquid wastes toxic gases. Owing such issues, this work presents alternatives preparing technical using reactive grinding mix its components. Particularly, we prepared series catalytic extrudates in hydrocracking tetralin....
