Abstract The present invention relates to a micro-metallic aluminium silicon phosphate type molecular sieve MeAPSO, its anhydrous chemical composition can be represented by mR.nMe.(Six Aly Pz)O2, in which R is template agent being in micropores of molecular sieve, m represents molal quantity of template agent corresponding to every mole (Six Aly Pz)O2, m=0.001-8.00, Me is metallic atom coming into skeleton of molecular sieve, n is molal quantity of Me corresponding to every mole (SixAlyPz)O2, n=0.001-0.60. x,y and z respectively represent mole fractions of Si, Al and P, their range respectively are: x=0.001-0.98, y=0.01-0.60, z=0.01-0.60, and x+y+z=1. Said molecular sieve can be used as ion-exchanging agent and adsorbing agent, and also can be used as catalyst for conversion reaction of several hydrocarbons.
