Abstract
Inventia se refera la un procedeu pentru prepararea prin sinteza hidrotermala a zeolitilor supersilicosi de tip ZSM-5 din solutii de silicat de sodiu si sulfat de aluminiu, acidulate cu acid sulfuric în prezenta de etilenglicol, în scopul obtinerii unui produs de cristalinitate si puritate maxima si anume, o solutie de silicat de sodiu tehnic se gelifiaza cu etilenglicol, se aciduleaza cu acid sulfuric, se amesteca cu solutie de sulfat de aluminiu tehnic cu formarea gelului de aluminosilicat având compozitie: SiO2:Al2O3=40...120, Na2O:SiO2=0,08...0,12. HO - :SiO2=0,16...0,24, H2O:Al2O3=1000...3000, H2O:SiO2=18...50, etilenglicol: SiO2=0,5...5.
