Abstract: The invention concerns a simple and cheap method for production of microporous crystalline metalloaluminiumphosphates (ELAPO) for use as adsorbent or catalyst by wholly or partially filling the pores of particles containing aluminum phosphate (AIPO) with an aqueous mixture containing an active source of metal and an organic structure directing agent and perform crystallization at elevated temperature under autogenous pressure to form crystals of ELAPO.

Abstract: The invention concerns a method for production of microporous crystalline metalloaluminium phosphates (ELAPO) based adsorbents or catalysts by in-situ crystallisation of ELAPO inside a formed body. First the formed body containing aluminium phosphate (AIPO) and binder is prepared, thereafter the organic structure directing agent, EL source and water are added and finally ELAPO is crystallised in-situ at elevated temperature and pressure, while keeping the shape and size of the formed body.
