Title (EN) PROCESS FOR THE SYNTHESIS OF SILICOALUMINOPHOSPHATE MOLECULAR SIEVES
(FR) PROCEDE DE SYNTHESE DE TAMIS MOLECULAIRES A BASE DE SILICO-ALUMINOPHOSPHATE
Abstract: front page image
(EN)The invention is directed to a method for making a silicoaluminophosphate (SAPO) molecular sieve from a reaction mixture comprising components present in amounts sufficient to form the SAPO, the reaction mixture having a first pH. The method comprises the steps of: adding an acid to the reaction mixture after the reaction mixture undergoes a change in pH from the first pH; and crystallizing the SAPO from the reaction mixture. The present invention is also directed to a silicoaluminophosphate molecular sieve made by this process.
(FR)L'invention concerne un procédé de préparation d'un tamis moléculaire à base de silico-aluminophosphate, à partir d'un mélange de réaction comprenant des composants présents dans des doses suffisantes pour former ce silico-aluminophosphate, le mélange de réaction possédant un premier pH. Ce procédé comprend les étapes suivantes consistant: à ajouter un acide au mélange de réaction, après que ce mélange ait subi un changement dans son pH, à partir du premier pH, et à cristalliser le silico-aluminophosphate à partir du mélange de réaction. L'invention concerne également un tamis moléculaire à base de silico-aluminophosphate préparé au moyen de ce procédé.
