Conteúdo: |
The use of the residues from renewable feedstock, besides the production of power and heat, but also for the generation of chemicals products, has become a priority. Superior plants have considerable potential as carbohydrate, aryl and fat acids sources. However, the separation of the main constituents of the samples is necessary for several purposes in the biorefinery concept. The acid hydrolysis is a very promising technology, however it was detected carbohydrates (14-17%) in the residues after the conventional acid hydrolysis of some uncommon biomasses (e.g. coffee husk and banana stem and stalk), indicating the adjustment need of the hydrolysis conditions for different biomasses. On the other hand, it was showed that, by pyrolysis, it is possible to obtain, from the solid residue after acid hydrolysis: pyrogenic carbon (charcoal: 45-65%) for agriculture use; and valuable chemicals in the biooil fraction, such as lignin monomers (32.6-56.4%) and fat acids (30-52.5%). |
