Yield, Composition, and Property of Biochar Obtained from the Two-Step Pyrolysis of Rice Husk Impregnated with Boric Acid
Adding catalysts such as boric acid into biomass is a flexible method to achieve high biochar yield with low carbon emission levels. This work is directed towards investigating the effects of boric acid content on biochar yield, composition, and property through a two-step pyrolysis of rice husk. The results showed that biochar yields, compositions, and properties were associated with the amoun...
متن کاملAdsorption of Lead from Industrial Effluents using Rice Husk
Rice husk a very low cost material has been utilized as adsorbent for the removal of lead from industrial effluents. Adsorption studies have been carried out at 28°Cand the effect of initial lead concentrations (100-1000) mg/l, adsorbent dosage (0.05-1) g, pH (2-10) and contact time (10-180) min on lead uptake to establish a mathematical model description percentage removal of Pb (II). The infl...
متن کاملBasic dyes removal from wastewater by adsorption on rice husk carbon
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...
متن کاملCharacteristics and mechanisms of nickel adsorption on biochars produced from wheat straw pellets and rice husk
The adsorption characteristics and mechanisms of Ni2+ on four-standard biochars produced from wheat straw pellets (WSP550, WSP700) and rice husk (RH550, RH700) at 550 and 700 °C, respectively, were investigated. The kinetic results show that the adsorption of Ni2+ on the biochars reached an equilibrium within 5 min. The increase of the solid to liquid ratio resulted in an increase of Ni2+ remov...
متن کاملcharacterization and sodium sorption capacity of biochar and activated carbon prepared from rice husk
biochar and activated carbon, as carbon-rich porous materials, have wide environmental applications. in the present research, rice husk (rh) was used for preparation of biochar at 400, 600, and 800 °c under simple pyrolysis, physically-activated carbon with water steam, chemically-activated carbon with potassium hydroxide (koh), and physiochemically-activated carbon with koh and steam. physical...
