Elephant grass is a fast growing and low nutrient demand plant with significant potential as a renewable energy source. In this work, the influence of heating temperatures, N2 sweeping gas flow rates and CaCl2 catalyzer weights on the yields of products and chemical composition of bio-gas was investigated by pyrolysis and catalytic pyrolysis of elephant grass in a fixed bed reactor. The results showed...
This paper reported rice straw pretreated by cellulase can produce methane by anaerobic batch fermentation at 30??C with 6% of TS in 400 ml reactor. The results showed: Group B (time of cellulase treatment for 48 h) got the highest biogas production for 3188 ml, and group C (time of cellulase treatment for 24 h) got the gas production for 2718 ml. Both group B and group C biogas production increased...
Since 2006, the government of the Lao PDR has strongly promoted biofuel development, on the basis of national energy security concerns, and interests for rural development. As a result, many farmers were encouraged to cultivate jatropha as a biofuel feedstock through government campaigns and private sector investment. For most, the return on their investment has been woefully low; a domestic biofuel...
Two kinds of physical methods, vacuum evaporation and steam stripping, combined with overliming (calcium hydroxide) were applied to remove inhibitors which were produced simultaneously during the pretreatment of lignocellulosic biomass. Corn stover was steam exploded; the filtrate was hydrolyzed with dilute sulfuric acid. The acid hydrolyzate was then detoxified and fermented by yeast. Physical methods...
