Biomass Pretreatment for Gasification

摘要：

Fresh biomass can be used as fuel to reduce net CO2 emissions,but may require processing to improve fuel qualities prior to use in thermal conversion facilities.Processing fresh banagrass,a fast-growing tropical plant,by mechanically removing juice and water-soluble elements using a screw press is explored.Treatments were found effective in reducing ash content including alkali and alkaline earth metals,as well as chlorine.Fuel analysis indicated that the treated banagrass had lower ash content,improved heating value,higher ash deformation temperatures,and higher volatile matter to fixed carbon ratios,than the untreated material.The elemental composition of the residual liquids from the treatment process was determined.From this preliminary analysis,the liquids appear suitable for irrigation or use as fertilizer
