However, with the replacement ratio increasing, the consistency of heat front and flame front is broken, and the thermal utilizing efficiency of fuel is reduced, which results in the decrease of yield and tumble index of sinter. Circulating flue gas to sintering bed as biochar replacing 40% coke, CO in flue gas can be reused so as to increase the thermal utilizing efficiency of fuels, and the consistency of two fronts is recovered for the circulating flue gas containing certain CO2, H2 O and lower O2, which contributes to increasing the maximum temperature, extending the high temperature duration time of sintering bed, and results in improving the output and quality of sinter. In the condition of circulating 40% flue gas, the sintering with biomass fuels is strengthened, and the sintering indexes with biomass fuel replacing 40% coke breeze are comparative to those of using coke breeze completely.展开更多

A pilot plant for cellulosic ethanol production with a capacity of one ton in dry biomass per day was established in 2007 and launched test-run operations for mass production in early 2010. The feedstock is focused on rice straw currently, but is also flexible for sugarcane bagasse and hardwood. The operative experiences and the experimental data will provide valuable information for the evaluation of production cost as well as the foundation for design of a commercial production plant in Taiwan. Additionally, this pilot plant will also serve as an important platform for validation of technologies related to cellulosic ethanol production and biorefinery operations. The biomass-to-ethanol process of this plant is based on the route of biochemical conversions. Developed and developing technologies, such as acid hydrolysis pretreatment, high solid to liquid ratio hydrolysis, in-house cellulase production, xylose fermentation, and the distillation and dehydration processes will be introduced.展开更多
