摘要
Abstract
A series of X zeolite catalysts with KOH and H3BO3 were characterized by means of in situ FTIR and the adsorption/coadsorption of methanol and/or toluene on the modified X zeolite catalysts were investigated. The influences of KOH concentration and H3BO3 loading on the coadsorption of methanol/toluene were studied. The relationship between the quantitative results of the coadsorption and the catalyst performances was researched. It was showed that,the peak areas and the area ratios of the methanol characteristic peak at 2 824 cm-1 and the toluene characteristic peak at 1 596 cm-1 could be used to quantitatively describe the adsorption capacity of the catalysts to methanol and toluene,and the in situ FTIR results could be correlated with the performances of the catalysts. The quantitative-analysis method can provide an important approach for developing high performance catalysts used in the side-chain alkylation of methanol and toluene.关键词
