Abstract
Process for manufacturing an alkali metal aluminosilicate of zeolite P type, wherein sodium silicate solution, sodium aluminate solution and sodium hydroxide are mixed together in a first reacting zone, the mixture reacting to form amorphous aluminosilicate and supersaturated mother liquor and being then transferred from this first reacting zone to a second reacting zone, the transferred mixure having a degree of crystallinity below 30%, preferably 20%, the mixture being afterwards allowed to fully convert into P type zeolite, the resulting product being eventually filtered, washed and dried.
