The study of the reactivity catalysts requires one to assess chemical kinetics and mechanisms in absence mass transport artifacts. Despite existence models criteria for assessing presence transfer limitations during catalytic tests gas-phase reactions isothermal fixed bed reactors, literature does not present straightforward protocols performing latter calculations. In this work, we a systematic protocol calculations above. Particularly, estimating effectiveness factor external Weisz-Prater...
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...
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...

The study of the reactivity solid catalysts requires assessing chemical kinetics and mechanism in absence mass transport artifacts. These artifacts consist formation concentration gradients either on external or internal (inside nanopores) surface solid.
