| titleOfInvention | PROCESS FOR THE PREPARATION OF ZEOLITES X AND LSX AGGLOMERATED AND EXCHANGED WITH LITHIUM |
| abstract | The present invention relates to a process for preparing X and LSX zeolites agglomerated with a binder and in which approximately 50 to approximately 99% of the exchangeable sites are lithium ions, which consists in carrying out the lithium exchange of part of the exchangeable cations of the starting zeolite by contacting said zeolite distributed in a carousel of at least 2 containers in the form of a fixed bed arranged in series interchangeably, with a solution of lithium compounds (1) conveyed through the carousel and changed cyclically at given time intervals; when the desired lithium exchange rate is reached for the zeolite of the 1st container, the latter is dissociated from the carousel and the zeolite contained therein is freed from the solution of lithium compounds by washing then discharged (4) and optionally replaced by a new charge of zeolite to be exchanged and is characterized in that a purge (5) of the flow corresponding to the excess lithium used is performed, distinguishing it from the effluent generated by the carousel and extracting from the carousel : - first the flow (5) corresponding to the percolation "e" at the outlet of the head column of the carousel, - then the flow (3) corresponding to the percolation "Eo" at the outlet of the carousel. This process makes it possible to d 'achieve a high level of lithium exchange with a greatly improved lithium yield compared to the methods of the prior art. |
