Abstract

Experimental results are reported for the adsorption of propane and n-butane in a column packed with Linde 5A zeolite crystals, and methane, propan n- and iso-butane in a column packed with silicalite crystals. The adsorption equilibrium constant K and crystal diffusivity D_c, we obtained at different temperatures in the range 100-300°C, for each sorbate and packing and the heat of adsorption and diffusional activation energ were determined. The results show that in order to separate the effects of K and the pressure drop, the latter must be independently estimated by a suitable correla.
