| 简介 |
The invention relates to process for furfural from xylose by using heterogeneous catalyst. Reactions are carried out in batch reactor by using mixture of solvents. Effect of temperature, amount of catalyst loading and xylose concentration are studied in detail. Xylose conversion and furfural yield are increased with increasing temperature and amount of catalyst. Xylose conversion is 92% with furfural yield 67% achieved after 3 h at 170 °C. Catalyst is recycled several times without loss of its activity. (I) ICaT-2 is prepared by a co-condensation sol-gel route. Hexadecyl amine was dissolved in ethanol and water mixture. Mixture of tetraethyl orthosilicate and 3-(mercaptopropyl)trimethoxysilane were added to the above solution. It is treated with lanthanum chloride (400 mg) for 2 h. The slurry was filtered and treated with trifluromethanesulfonic acid (5.4 mmol) at 30 °C for 2 h. The slurry was filtered and washed with water and dried under vacuum to get the active ICaT-2 catalyst. |
