Water vapor adsorption/desorption on granulated binder-free low-module zeolites

A characteristic of granulated LTA and SOD zeolites is given. It was determined that zeolite particles have a cube shape with size ~2 μm; an irregular 0.5–1 μm. The dimension the coherent scattering region calculated to be 760 nm for 453 SOD. specific surface area 115 m2·g–1 141 m2·g–1. Static tests showed maximum quantity absorbed water vapor ~30 wt.%, ~20 wt.%. found provide adsorption from gas dew point –50 °C, –9 °C. apparent activation energies desorption on were using isoconversional analysis Friedman, Ozawa–Flynn–Wall, Kissinger–Akahira–Sunose.
