摘要：
The acid dealumination of various samples of ZSM-5 is studied using mineral acids as the dealuminating agent. Apart from the synthesis method of the ZSM-5, the acid concentration, the temperature, and the duration of the acid treatment are varied. The results are evaluated using elemental analysis and Al-27 MAS n.m.r. A comparison with literature data is presented. it seems that the dealumination of MFI is not as straightforward as is often assumed. (C) Elsevier Science Inc. 1997
