Preparing spherical lignin from rice husk
Bioprocess and Biosystems Engineering, 2012Lignin is one of the important branched amorphous polymers, which generally has the irregular and fractal morphology. The preparation of regular sphere of lignin needs long steps and special conditions. In this study, the regular sphere of lignin can be simply prepared from rice husk (RH) under certain conditions.

A Short Review on Fly Ash, Rice Husk Ash and Rice Husk Composites
International Journal of Emerging Trends in Engineering Research, 2021Fly ash is generated during the combustion of coal and rice husk ash is generated by the combustion of rice husk for energy production. Fly ash is industrial waste and rice husk ash is agricultural waste that is widely available worldwide.

Rice-husk (RH) is an agricultural by-product material. It constitutes about 20 % of the weight of rice. It contains about 50 % cellulose, 25–30 % lignin, and 15–20 % of silica. When rice-husk is burnt rice-husk ash (RHA) is generated. On burning, cellulose and lignin are removed leaving behind silica ash.

Effect of lime:silica ratio on the kinetics of the reaction of silica with saturated lime has been investigated. Below C/S=0.65 the reaction does not proceed to completion and even in the presence of a large excess of silica only 90% lime is consumed. A parameter, lime reactivity index, has been defined to quantity the reactive silica present in rice ...
