Thermal characteristics of rice hulls
Journal of Chemical Technology and Biotechnology, 1981AbstractEvaluation of the thermal characteristics of rice hulls is described. Decomposition was negligible below 200°C, but on heating above 200°C, the amount of volatile matter evolved increased steadily with increasing temperature up to 450°C, where > 90 % of the total volatile matter was separated.

Wild rice hulls (WRH) have not been utilized in any valuable manner. Minnesota WRH have been shown by us to possess antioxidant properties. The methanol extract of hulls showed antioxidant activity when added to ground beef, as evaluated by the content of thiobarbituric acid reactive substances (TBARS). The results of an ammonium thiocyanate assay also

Tar Cracking in a Rice Hull and Rice Hull Pellet Fuel Bed
1984The renewed interest in small gas producer-engine systems (5–100 hp) has mostly involved downdraft (co-current) gas producers because of their ability to convert condensable pyrolytic products into noncondensable combustible gases. The evolution of gas producers for use with internal combustion engines has taken place as shown in Figures 9-1 through 9 ...

Rice Hulls-To-Silicon Revisited
2006 IEEE 4th World Conference on Photovoltaic Energy Conference, 2006In a three-step process, rice hulls were purified and then converted into upgraded metallurgical silicon suitable for ingot production using directional solidification and solar-grade wafers. Pilot production of this new solar cell feedstock has successfully demonstrated solar cell efficiencies comparable to high purity polysilicon produced by ...

Characterization and immunomodulatory activity of rice hull polysaccharides
Carbohydrate Polymers, 2015Rice hulls (Oryza sativa) are high in carbohydrate content and have been utilized as dietary fiber. The immunomodulatory bioactivity of rice hull polysaccharides (RHPS) has rarely been reported. This study demonstrated the structural characteristics and immunomodulating of RHPS. The RHPS were fractioned using DEAE-650M column, producing one neutral and

Formation of Silicon Carbide from Rice Hulls
Canadian Metallurgical Quarterly, 1997Abstract SiC whiskers and particles have been produced from rice hulls. The process involves three major steps: coking in free air, reaction at high temperature in a reducing atmosphere of hydrogen gas, and separation of formed SiC from excess carbon by wet methods. The processing steps are reviewed and the chemistry of the process is discussed.

Rice hull biocomposites. I. Preparation of a linseed‐oil‐based resin reinforced with rice hulls
Journal of Applied Polymer Science, 2011AbstractBiocomposites consisting of a conjugated linseed‐oil (CLO)‐based thermoset reinforced with rice hulls were prepared by free‐radical polymerization initiated by t‐butyl peroxide. The resin composition was kept constant at 50 wt % CLO, 35 wt % n‐butyl methacrylate, and 15 wt % divinylbenzene.

Pretreatment of rice hulls by ionic liquid dissolution
Bioresource Technology, 2012As a highly available waste product, rice hulls could be a starting block in replacing liquid fossil fuels. However, their silica covering can make further use difficult. This preliminary study investigates effects of dissolving rice hulls in the ionic liquids 1-ethyl-3-methylimidazolium acetate (EMIM Ac), 1-hexyl-3-methylimidazolium chloride, (HMIM Cl)

The composition of lipids from rice hulls and from the surface of rice caryopsis
Journal of the Science of Food and Agriculture, 1976AbstractSamples of hulls, of whole and ground caryopsis and of bran obtained from the Brazilian rice variety IAC 1246, were extracted with hexane and the characteristics and composition of the corresponding lipids were determined. The lipids from rice hulls showed a four times higher content of unsaponifiable matter and of free fatty acids than those ...
