Liquid phase hydrogenation of tetralin on Ni/Al2O3

Naphthalene hydrogenation over a NiMo/γ-Al2O3 catalyst: Experimental study and kinetic modelling

“…Although not statistically significant, the removal of these parameters from the model visually affected the parity diagram and, hence, in the final regression these parameters were fixed at average values obtained during the regression procedure using various initial parameter guesses. The trend among the hydrocarbon chemisorption enthalpies indicates that naphthalene is more strongly bound to the surface than tetralin which is line with other hydrogenation studies of these molecules [47,48].…”

Comparative study of the hydrogenation of tetralin on supported Ni, Pt, and Pd catalysts

“…Tetrahydronaphthalene (tetralin) has been frequently used to represent aromatics in diesel fuels in hydrogenation reactions [21][22][23][24][25]. The most widely accepted hydrogenation pathway includes D 1,9 -octalin (octahydronaphthalene) as an intermediate that is further hydrogenated to the cis-or trans-decalin product.…”

The Reactants’ Phase State: A Nonnegligible Factor in Tetralin Hydrogenation Catalysts Evaluation

“…This difference probably affects the 2 International Journal of Chemical Engineering hydrogenation activity of catalyst and leads to the decrease of aromatics conversion. Generally, model compounds are composed of aromatics and inert hydrocarbons; for example, naphthalene dissolves in -hexadecane [16][17][18][19], -tridecane [20,21], -decane [22], -heptane [5,[10][11][12][13][14]23], and benzene [4] or tetralin dissolves in -dodecane [24], -decane [22,25,26], -heptane [6-9, 12, 15, 27, 28], -hexane [29], and cyclohexane [30,31]. The model compounds using light components as solvents are easier to vaporize and have lower dew point.…”
