“…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.…”
