Název v původním jazyce
Effect of Acid Sites od Al- and Fe- Ferrierite on m-Xylene Isomerization.
Popis výsledku v původním jazyce
Metal analogs of Ferrierite (FER) have been prepared by incorporating Fe by single route and Al by three different routes (a) using pyrrolidine (b) in presence of promoting media (perchloric acid) and (c) in presence of anionic surfactant sodium bis-(2-ethylhexyl) sulpho succinate, (AOT) and characterized by FTIR using CD3CN as probe molecule to study acid sites of these samples. D3-Acetonitrile adsorption on these samples showed a band at 2297cm-1 corresponding tof nitrile group with Brönsted acid sites and a band at 2322cm-1 due to interaction with Lewis acid sites. The concentrations of Brönsted and Lewis acid sites were calculated by using the reported extinction coefficients. The concentration of Bronsted acid sites was found to decrease in the order Al-FER(PER) > Al-FER(AOT) > Al-FER(H2SO4) > Fe-FER. The TPD of ammonia of FER samples was carried out to find the acid strength of the samples which decreased in the order Al-FER (PER) > Fe-FER > Al-FER (AOT) > Al-FER (H2 SO4).
