The research results presented in the article are devoted to the compressed air adsorption drying processes energy intensity reducing possibilities study. The investigation concerns the new adsorbent – composite. The material is considered as one of the most perspective at the present time. It’s ehergy efficiency is proved comparing traditional adsorbents such as silica gel, alumogel, zeolites, etc. The authors consider the bulk density as one of the factors at the adsorption process energy efficiency increase. The formulas given at the articles allow to calculate the different adsorbents bulk and apparent density, the compressor’s energy efficiency by using different adsorbents at pneumatic schemes, etc.
