초록

Due to a world trend on renewable energy, biomass that is one of renewable energy resources has to be applied at thermochemical process, actively. However, in commercial plant, one of many problems is an agglomeration production at biomass thermochemical process, because it leads to disturb continuous operation on thermochemical process. Thus, in this study, the EFB (empty fruit bunch), one of palm oil industry by-products was used as a biomass fuel, and washed by water and nitric acid solution (0.1wt.%) with different total washing times for resolving this problem at biomass thermochemical process. After washing, ash content was decreased from 5.9wt.% to 1.53wt.% using all of the washing treatments, and the Alkali & Alkaline Earth Metallic (AAEM) was removed over 80wt.% of total AAEM, such as potassium, magnesium, calcium and sodium. Additionally, SEM with XRD was analyzed to confirm the characteristics of produced agglomeration, and the agglomeration production ratio was measured: it revealed that the ratio was resulted in decrease over half, in the case of using all of washed EFBs.
