| Research Abstract |
In order to establish a conversion process from biomass into basic chemicals, the hydrothermal conversion of bagasse or molasses in the pre-treating step and the catalytic conversion of the pre-treating products with zeolite catalyst in the second step were investigated. As the pre-treating of the biomass, hydrothermal reaction of the bagasse or molasses using only water or acid-added water was carried out, and the suitable conditions, product yields and the effect of using acid were clarified. The effect of intermediate species obtained in the pre-treating step on the species and yields of the product in the catalytic conversion step was also investigated. As a results, it was concluded that BTX was mainly obtained from levulinic acid, mixture of mono-and di-aromatic chemicals from 5-hydroxymethylfurfural or glycolaldehyde, and mainly di-aromatic chemicals and coke from mono-saccharides. For enhancing BTX yields and reducing coke formation, it was found that the diffusion of the intermediates into zeolite pores was important and the unsteady-state reaction operation was an effective reaction method.
