- Abstract:
- ZSM-5 zeolite with different Si/ Al ratios was selected as catalyst carrier and the salt of the NaAICl,as the surface load.The catalytic performance with different Si/Al ratios at different temperatures was com-pared to investigate the effects of Si/ Al ratio. Commonly used,the catalysts were characterized by X-ray dif-fraction (XRD),GC,scanning electron microscope ( SEM),BET and NH, -TPD and so on. The catalystwhich Si/ Al ratio was 38 had the greatest acidity and was the most active one. The results showed that the cat-alytic activity depended on the surface area at low temperature,while at high temperature depended on the ac-tivation sites.When Si/ Al ratio was 38,at 373 K,Cat-4% showed the best catalytic effect,of which yield ofdichlorodimethylsilane was 57. 9 % .
