Abstract:The adsorption/desorption behaviors of 17 organic compounds on synthetic pure silica BEA type zeolite were investigated by means of TG/DTG/DTA analysis. The organics used as the adsorbates were alkanes, aromatics, alcohols, and alkylamines. A T value, the affinity index determined by DTG was used to characterize the interaction between the organic adsorbates and the perfect framework of the zeolite. The hydrophobic framework of the zeolite shows stronger affinity to the organic molecules containing amino and alkyl groups than those with hydroxyl groups. The nature of the sorbate/framework can be identified from the A T values, isosteric heat and interaction energy.
Keywords:SILICON  ZEOLITE  THERMAL ANALYSIS  ADSORPTION  AMINES  ALKANE  AROMATIC COMPOUNDS  INTERACTIONS
