Abstract EN
Rice husk is an abundant agricultural by-product reaching the output of 80 million tons annually in the world.
The most common treatment method of rice husk is burning or burying, which caused serious air pollution and resource waste.
In order to solve this problem, a new method is proposed to comprehensively utilize the rice husk in this paper.
Firstly, the D-xylose was prepared from the semicellulose via dilute acid hydrolysis.
Secondly, the lignin was separated via organic solvent pulping from the residue.
Finally, the amorphous ultrafine silica was prepared via pyrolysis of the residue produced in the second process.
In this way, the three main contents of rice husk (semicellulose, lignin, and silica) are consecutively converted to three fine chemicals, without solid waste produced.
The yields of D-xylose and organosolv lignin reach 58.2% and 58.5%, respectively.
The purity and specific surface of amorphous ultrafine silica reach 99.92% and 225.20 m2/g.
