乙苯在不同粒度β沸石上的裂化

Crack of Ethylbenzene on β Zeolites with Different Granularity

本文报导通过改变反应条件,合成出不同粒度的β沸石,利用吡啶吸附红外光谱法研究各沸石的表面酸性,测定不同粒度β沸石的比表面积和比孔容,利用苯和乙苯在其上的吸附与扩散性能研究解释β沸石在乙苯裂化反应中的粒度效应。

In this paper, β zeolites with the different granularity were synthesized by changing reaction conditions. The surface acidity of β zeolites were studied by absorbing Py-IR spectrum method, and the specific surface area and the specific pore Volume of β zeolites were determined. The granularity effect of β zeolites in crack reaction of ethylbenzene were explained by study on absorption and diffussion properties of benzene and ethylbenzene.
