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.
