ABSTRACT:
The filter press cake, obtained by separation of the raw Zeolite from the major portion of the mother liquor and not washed, or only partially washed, is additivated with a suitable surface-active agent, added in the amount of from 1 to 2% in weight on the weight of the wet Zeolite. The thus-fluidized Zeolite is treated in a high-turbulence zone with sulphuric acid at a concentration greater than 70%, which is added in such an amount as to produce a nearly complete neutralization of the final Zeolite.
