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.
