چکیده انگلیسی


• A novel solid acid was prepared from rice husk.
• The solid acid shows ultra high surface area of 1233 m2/g.
• Its acid strength is stronger than that of HZSM-5 zeolite.
• The solid acid exhibits excellent activity and stability for esterification.

A porous carbon solid acid was synthesized from biomass rice husk by incompletely carbonization, sodium hydroxide leaching and concentrated H2SO4 sulfonation. The solid acid was characterized by XRD, FT-IR, N2 adsorption-desorption and solid-state NMR spectroscopy. The characterization results reveal that the carbon solid acid shows ultra high surface area of 1233 m2/g and stronger acid strength than that of HZSM-5(Si/Al = 38) zeolite. The catalytic performance was tested by the esterification of oleic acid with methanol. The results indicate that this solid acid catalyst is an excellent catalyst compared with other conventional solid acid.
