PROPANOLUN La- VƏ Pd- TƏRKİBLİ NaX SEOLİT KATALİZATORLARI İŞTİRAKINDA OKSİDLƏŞMƏ PROSESİNİN TƏDQİQİ

Abstract

Catalyst samples based on NaX zeolite and La, Pd metals were synthesized using the ion-exchange method and their activity was studied in the process of n-propanol oxidation in the temperature range of 423-723K. It was determined that the degree of conversion of alcohol and the yield of reaction products on the modified samples are significantly increased compared to the original NaX sample. According to the conducted studies, it was determined that at relatively low temperatures, the intramolecular and intermolecular dehydration reactions of alcohol prevail, while at high temperatures, its partial and complete oxidation reactions accelerate. It was determined that the method of modification of primary NaX zeolite allows to optimize the phase composition of the synthesized catalyst and the size of the active component, which allows to adjust the yield of the main reaction products and lower the temperature limit of the reaction.
