Though potentially useful, agricultural byproducts are often discarded because of the lack of specific applications in many industries. However, they have suitable properties for use in the paper industry, according to recent literature. In this study, the suitability of rice husk, peanut husk, and garlic stem as raw materials for the manufacture of a new lignocellulosic bulking agent was inves...

In this study, effect of biomass share on co-combustion of coal and biomass in a circulating fluidized bed is investigated by previously developed model. SO2 and NOx emission predictions of the model are compared with test results obtained from the laboratory-scale 30 kW (thermal) atmospheric test unit of 0.86 m i.d. and 7 m tall riser data published in the literature. Simulation results show t...

in this research, rice husk and activated carbon adsorbents were used for removal of lead ion from aqueous solution at ph= 6. in the batch tests experimental parameters were studied, including contact time and initial metal ions concentration.survey of the equilibrium time at different concentration showed that equilibrium time is reduced with decrease of initial concentration of solution from ...

presence of heavy metals in the aquatic systems has become a serious problem. as a result, therehas been a great deal of attention given to new technologies for removal of heavy metal ions from contaminated waters. adsorption is one of the effective methods for removal of toxic heavy metal such as chromium (vi). in the present study, adsorbent is prepared from rice husk, a low cost by product f...

The metabolic fate of l-ascorbic acid-1-(14)C and -6-(14)C has been investigated in two species in two genera of Vitaceae. Results suggest that ascorbic acid metabolism in the Vitaceae involves splitting the 6-carbon chain into 4- and 2-carbon fragments. The former, corresponding to C1 through C4 of ascorbic acid, is further oxidized to tartaric acid while the latter, corresponding to C5 and C6...

Fiber reinforced concrete is a composite material consisting of mixtures of cement, fine aggregate, coarse aggregate and fibers. The fiber reinforced concrete exhibits better fatigue strength and increased static and dynamic tensile strength and compressive strength. In this project, the strength of fiber reinforced concrete was investigated partial replacement of cement with rice husk ash and ...

Rice husk carbon (RHC) has been prepared from rice husk impregnated with 50% H3P04 and carbonised at 300°C. Its adsorption capacity has been tested for the decolourization of wastewater containing safranine and methylene blue. The effect of system variables such as concentration, temperature, pH, contact time, adsorbent dosage and particle size are investigated. Removal of dye has been found to...
