几种加氢裂化催化剂的太赫兹光谱研究
Research on Several Hydrocracking Catalysts by Terahertz Spectrum
摘要
Abstract
Spectral characteristic of several Y type hydrocracking catalysts (NaY,ReY,USY and HY) are studied using terahertz time-domain spectroscopy (THz-TDS) in the range of 0.2-1.2THz.Meanwhile,molecular sieve NaY was heated at different temperatures and then was measured by THz-TDS.Through fast fourier transformation,both terahertz absorption spectra and refractive spectra of catalysts,which have different class and have been processed by different temperatures,were obtained.The results indicated that THz-TDS technology can not only be used to identify species and characterize properties of catalysts,but also provide terahertz spectral response corresponds to the changes of internal structure of catalysts at different temperatures.Through this work,the feasibility for characterization of catalysts using terahertz method is demonstrated,which can offer guidance in applications of THz technology in catalysis.关键词
