The Effects of Demineralization on Reducing Ash Content in Corn and Soy Biomass with the Goal of Increasing Biofuel Quality

The increasing amount of residual waste presents several opportunities to use biomass as a renewable energy source. Agricultural is raw material with high ash content, which can be problem in any form conversion. To obtain better quality biofuel, excess mineral matter must removed. Demineralization simple mixing and washing various liquids reduce content. Water, acetic acid, hydrochloric acid nitric are common solvents used for this purpose. Ash composed different micro (Zn, Cu, Fe) macro elements (Mg, Ca, K), have consequences the thermal energy. Different effects on individual elements, inorganic acids having greatest effect demineralization processes, reduction content up 80% corn about 99% soybeans.
