In this paper, the influence of process parameters on the morphological properties of fine precipitated hydrate was examined. The research was conducted with the aim of synthesizing fine precipitated aluminum hydroxide from the aluminate solution obtained by the Bayer process. Fine precipitated hydrates obtained in this way are mostly used in the n...

Based on relations for the maximum work at the closed thermodynamic system, the paper presents implementation of a general model for determining the minimum storage volume for compressed air. Due to the mechanical and thermodynamic imbalance of observed model, there are the conditions for obtaining the maximum work. Derived relations, which represe...

This paper studies the effect of process parameters on the sorption characteristics of zeolite 4A. The observed process are related to the influence of crystallization temperature, crystallization time and influence concentrations of Na2O. In parallel with the examination of the impact of these parameters on the capacity of water sorption of zeolit...
