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...
At the beginning and during development of civilization, natural sources were only available source energy. With society industry, they replaced by intensive use fossil fuels. Non-renewability negative impact on environment called into question rationality using such sources. Therefore, energy are becoming more important, especially biomass, which is an important due to its ecological advantages. There numerous ways convert agricultural biomass different forms biofuel.
