文摘

•: Mesoporous solids SBA-15, SBA-16, MCM-41 and MCM-48 were synthesised.
•: The adsorption isotherms of nitrogen were measured at −196 °C.
•: Adsorption isotherms of different nonlinear alcohols were measured at different temperatures.
•: The results obtained show that hybrid DA model is valid for the polar molecules used.
•: Differential heats of adsorption for each of the alcohols used in this work show three.
