Abstract
All types of ${\gamma}-Al_2O_3$ such as acidic, neutral and basic forms were chemically modified with (3-mercaptopropyl) trimethoxysilane (3-MPTMS) and oxidized by 30 wt% $H_2O_2$ solution. As a result, sulfonic acid modified ${\gamma}-Al_2O_3$ catalysts were obtained. Their formation was achieved more easily by treating 1M HCl solution. Their catalytic performance was tested by dehydration reaction of D-xylose to furfural. The sulfonic acid modified ${\gamma}-Al_2O_3$ catalysts showed high conversion (>90%) of D-xylose, and the selectivity to furfural was increased with the amount of sulfonic acid anchored on the catalyst.
