Heats of adsorption of hydrocarbons on solid surfaces

摘要

The integral heatws of the interphase interaction of liquid aliphatic and aromatic hydrocarbons with fibers and powders of jpolacrylonitrile and polypropylene,clay,and sandstone at 293 and 303 K were evaluated microcalorimetrically.The realationships between the heat of adsorption of hydrocarbons and the sorbate:adsorbent mass ratio were obtained.The heat and time needed for the interaction of hydrocarbons with the solid surfaces to reach equilibrium depend mainly on the adsorbent structure.
