Synthesis and studies of thermal stability of NaK-, K-, Na-, and Li forms of LSX zeolite

摘要

Samples of powdered zeolite LSX are synthesized that are characterized by high phase purity and a crystallinity degree close to 100% in NaK, K, Na, and Li forms. XRD and adsorption methods were used to elucidate the effect of the chemical nature and content of the exchange cation on the phase composition and characteristics of the porous structure and the thermal stability of the above forms of zeolite LSX.
