Synthesis of sodium zeolite w-z
Abstract
Abstract Sodium Zeolite W-Z and a process for making sodium Zeolite W-Z having the chemical formula: 1.0 + OR - 0.1 Na2O.Al2O3. 5.75 + OR - 0.55 SiO2.YH2O wherein Y is a number from 0 to 7 which comprises mixing sodium hydroxide, a source of silica, a source of alumina and water in the following mole ratios: Na2O/SiO2 0.8 to 1.9 SiO2/Al2O3 10.0 to 35.0 H2O/Na2O 100.0 to 160.0 TO OBTAIN A GEL-FORM MIXTURE, DIGESTING THE GEL MIXTURE FOR A PERIOD OF TIME FROM 12 TO 200 HOURS, HEATING THE DIGESTED MIXTURE AT A TEMPERATURE OF FROM 50* TO 150* C. for from 1 to 5 days and recovering sodium Zeolite W-Z. Sodium Zeolite W-Z can be ionexchanged to obtain a crystalline aluminosilicate having catalytic activity for use in hydrocarbon conversion processes.
