摘要：
The characterization and catalytic properties of chromium-containing silicate (Si-Cr) with a pentasil structure were studied. The Si-Cr was synthesized using an organic amine as the structure-directing compound. Based on infrared, X-ray diffraction and electron spin resonance measurements, it was found that chromium atoms exist in the highly dispersed state. In the conversion of methanol to hydrocarbons, the Si-Cr exhibited a high selectivity to C2-C4 alkenes, especially ethylene. And it was related to the existance of these chromium atoms in this silicate.
