The adsorption properties of molecules with different polarizabilities, benzene, cyclohexane, n-hexane and water, on aluminophosphate molecular sieve AlPO_4-11 have been investigated by gravimetric method, and compared with those on zeolites NaX and ZSM-5 having high Si/Al ratio.From adsorption data we have calculated the isosteric heat of adsorption and the differential molar adsorption work and entropy of benzene and cyclohexane on AlPO_4-11. The adsorption isotherms can be described by the theory of volume filling of micropores. The results show that the heat of adsorption of hydrocarbons on AlPO_4-11 mainly depends on the surface energy of dispersion.AIPO_4-11 favourably...
