The invention relates to a method for manufacturing zeolites in a reactor, comprising the following steps:
a) introducing water into the reactor,
b) introducing NaOH into the reactor, preferably in form of granules,
c) introducing fly ash into the reactor,
d) heating the mixture of water, NaOH and fly ash in the reactor to a temperature of 60°C to 90°C, preferably of 75°C to 80°C.
e) conducting zeolite synthesis reaction in the reactor over a period of 12 to 72 hours, preferably for 24 to 36 hours,
f) removing the product of step e) from the reactor and separating the zeolitic material from an aqueous solution of NaOH,
characterized in that
in step e) the reaction mixture in the reactor is alternately mixed by means of a mixer (6) and pumped out from the reactor (8) and again introduced into the reactor by means of a pump (10). The invention also relates to a device for performing the above mentioned method of producing zeolites. |
