摘要: 1. During the adsorption of nitrogen oxides by ASM grade silica gel, increase in relative saturation is accompanied a rapid fall total mass transfer coefficient caused increased diffusion resistance adsorbate pores adsorbent. 2. By criterial analysis experimental data and considering through gas film surrounding porous particle, it possible to generalize studies on adsorption, solution, sublimation, drying fluidized systems, as well results experiments from single drops particles. 3. A equation has been found, which defines coefficients between particles (liquid) region. 4. A distributionψ proposed for quantitative evaluation per unit bed uniform distribution gaseous phase; values this have determined conditions our those [1].
