摘要

process for the synthesis of silica alumina phosphate molecular sieve precursors by heating of a pressure contact u2267 autogenous reaction mixture containing sources of silicon, aluminium and phosphorus in the presence of an organic structuring agent and acid - orhydrique. the precursor obtained can be transformed into the molecular sieves by calcination.the silica alumina phosphate molecular sieve type are useful as adsorbents and catalysts for conversion of hydrocarbons.
