Abstract
Inventia se refera la un procedeu de preparare hidrotermala, la 160 degree C, timp de 72 h, a unui zeolit cu structura tip ZK-19, din compozitii initiale libere de agenti de dirijare structurala, caracterizate prin: SiO2/Al2O3=15-16; (Na2O+K2O)/Al2O3=9-11; H2O/Al2O3=190-300. Produsul obtinut manifesta selectivitate în adsorbtie si caracter hidrofob: capacitate de absorbtie a vaporilor de apa 1,5...1,9% si a n-heptanului 11,8% si prezinta, totodata, o structura ultrastabila termic.The invention relates to a process for the hydrothermal preparation of a zeolite of ZK-19 type zeolite at 160 ° C for 72 hours, from free initial compositions of structural guiding agents, characterized by: SiO2 / Al2O3 = 15-16 ; (Na2O + K2O) / Al2O3 = 9-11; H2O / Al2O3 = 190-300. The obtained product exhibits selectivity in adsorption and hydrophobic character: 1,5 ... 1,9% water vapor absorption capacity and 11,8% n-heptane and it also has a ultra-stable thermal structure.
