Isomerization of light alkanes catalyzed by ionic liquids: An analysis of process parameters

Silica-immobilized ionic liquid Brønsted acids as highly effective heterogeneous catalysts for the isomerization of n-heptane and n-octane

“…In contrast, at 40 C, yields were approximately equal; these equilibrium yields are easily achieved at high temperatures due to high reaction rates (kinetic limitation). Ibragimov et al 46 observed similar results for the isomerization of n-hexane in 1-methyl-3-butylimidazolium chloride with AlCl 3 .…”

Mobility and separation of linear and branched C5 alkanes in UiO-66 (Zr) probed by 2H NMR and MD simulations

“…After isomerization, nalkanes that have not been converted to branched alkanes are returned to the reactor. [1][2][3] Therefore, a mixture of branched and linear alkanes has to be separated. For light hydrocarbons, the typical boiling points of their isomers are relatively close which makes basic separation methods like cryo-distillation extremely energy consuming.…”
