one batch to be used as a raw material in subsequent batches of the same material the process improvements not only save on the high cost of conventional template recovery the 34 template 34 cation is either recovered on ion exchange columns or by steam stripping of effluents but also eliminates the disposal or recovery of the excess silica in the ml by ph adjustment settling and filtration followed by disposal or incorporation into the subsequently used silica alumina gel the template contents of the filtrates are readily measured by solution 13 c nmr methods facilitating rapid ml utilization in subsequent zeolite batches was prepared by first preparing a sodium aluminate solution by dissolving 48 5 g naoh in 100 ml distilled water to this solution 11 5 g of alumina trihydrate al 2 o 3 u00b7 3h 2 o 156 01 g mole alcoa c 31 was added and the solution was heated with stirring on a hot plate magnetic stirrer until the alumina dissolved the solution was cooled to room temperature to a one liter blender was added 269 8 g of n brand sodium silicate solution p q corp 8 9 na 2 o 26 7 sio 2.
