摘要
The integral heats of the interphase interaction of liquid aliphatic and aromatic hydrocarbons with fibers and powders of polyacrylonitrile and polypropylene, clay, and sandstone at 293 and 303 K were evaluated microcalorimetrically. The relationships 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.
