- W907177260 abstract "进一步研究了HZSM-5分子筛的NH4F预处理温度对制得的Mo／HZSM-5催化剂的影响．X射线衍射和魔角旋转固体核磁共振（^27Al MASNMR）的表征结果表明，NH4F预处理后的HZSM-5分子筛上发生了部分脱铝，在^27Al MASNMR谱中δ=-12．7处出现了宽化峰，可归属为AlO6-xFx的特征峰．Mo／HZSM-5样品的NH3程序升温脱附与^27Al MASNMR结果均表明，MoO3与经NH4F预处理的HZSM-5的相互作用增强，而且该作用随NH4F预处理温度的升高而加大＋经NH4F预处理的Mo／HZSM-5催化剂显示出良好的抗积碳性能，这不仅与载体B酸量的减少有关，而且与催化剂上MoCx／MoCxOy与载体B酸量的匹配有关．" @default.
