    Abstract: A method for the preparation of small zeotype crystals with controlled sizes comprising the steps of synthesizing inside a porous material having a majority of pores less than 1000 Å a synthesis gel consisting essentially of (a) a zeotype precursor composition comprising hydratized oxides of Si, Al and P and metal compounds (b) a zeolite template; and heating or autoclaving the porous support material containing synthesis gel, whereby zeotype crystals are formed; and rinsing and drying the porous support material containing zeotype crystals.
