摘要：High crystalline MCM-22 was synthesized by dynamic method hydrothermally,and it was characterized by means of XRD and SEM.After being ion exchanged with NH4NO3, the resulting HMCM-22 showed desirable catalytic properties for the hydrodealkylation of heavy aromatics, which gave a C9+conversion between those of HZSM-5 and Hβ , but exhibited the highest selectivity of 83.6% under the condition of 460℃, 3.0 MPa, 3.62 h -1 and the H2 to hydrocarbon ratio of 1600.
