Bio-zeoliteBio-inhibitionAddressing the significant challenge of efficiently separating 1,4-dioxane from aquatic environments using traditional adsorbents is crucial. In this study, we evaluated the adsorption performance of MCM-22 and Beta zeolites. Both were identified as highly effective adsorbents. ...

On the other hand, a beta zeolite with a small number of Lewis acid sites showed a better performance in the conversion of xylose into furfural than the one with a large number of Lewis acid sites. Suitable acid properties for the conversion of glucose and xylose are discussed in terms of...
PURPOSE: To obtain a crystalline porous three-dimensional solid catalyst having a structure and composition of β-zeolite which is used in the isomerization process of an n-paraffin and to provide a method capable of promoting the catalytic performance (catalytic activity and selectivity) of thi...
