Abstract Sorption of C6 alkanes viz.,n-hexane, 2-methylpentane, 2,2-dimethyl butane, 2,3-dimethyl butane, cyclohexane and methyl cyclopentane in AlPO4-5 is studied and sorption capacity and thermodynamic parameters (ΔH0, ΔH, ΔG, ΔS and Sa) at various sorption coverage for these sorbates have been estimated. The initial heat of sorption (ΔH0) is found to increase with the degree of branching in the alkane chain. The sorbate-sorbate interactions are found to be more prominent during the sorption of doubly branched alkanes and cyclic alkanes and a higher sorption capacity has been observed for cyclic alkanes. Based on the results obtained, a packing model has been proposed for various C6 alkanes inside the AlPO4-5 channel.
