| titleOfInvention | Process for the preparation of agglomerated zeolites x and lsx exchanged with lithium |
| abstract | The present invention provides a process for the preparation of zeolites X and LSX in which about 50 to about 99% of the exchangeable sites are agglomerated with a binder filled with lithium ions, comprising exchanging a portion of the exchangeable cations of the starting zeolite with lithium, The exchange consists of contacting the zeolite distributed in two or more vessels in a static bed form, arranged in series, in a mutually changeable manner, with the lithium compound solution 1 being transported through the carousel, The sequence of vessels is adjusted cyclically at a given time interval; When lithium is exchanged in the first vessel by the desired amount in the zeolite, the first vessel is removed from the series of carousels, the zeolite present in it is washed to remove the solution of the lithium compound and discharged (4) Exchanged with a fresh zeolite charge to be optionally exchanged, the bleed 5 being separated from the effluent generated by the carousel and discharged from the stream corresponding to the excess of lithium used andn n n The first stream 5 corresponding to filtration "e" at the outlet of the head column of the carouseln n n Subsequent stream (3) corresponding to the filtration "E 0 " at the outlet of the carousel.n n n (“E 0 ” is the stoichiometric equivalent of exchangeable lithium in a sieve and “e” is the excess required to obtain the desired degree of exchange for lithium, preferably greater than 96%) in the carousel Dischargedn n n It is related with the manufacturing method of X type zeolite characterized by the above-mentioned.n n n The method makes it possible to achieve a high level of lithium exchange with significantly improved lithium yield over the prior art methods. |
