pretreatment - Opis:
- An agricultural waste substrates such as rape straw, hay, corn stover, or other types of green fodder (grass residues) are not utilized in many farms and go to the waste, which finally goes to the soil. Therefore, it is very important to appropriately manage these substrates, for example, in methane fermentation process for the biogas production. During the process of methane fermentation in agricultural biogas plant, mentioned biomass substrates are decomposed only in a small extent. The low biodegradability of straw and grasses is related to their chemical structure. The composition of this materials includes cellulose and hemicellulose compounds surrounded with the lignin polymers (hence, in the literature the name of lignocellulosic biomass is used), which is not digested in this form by enzymes of the methane bacteria. It is assumed that a suitable technological pretreatment of the batch (by micronization or steam explosion) may significantly improve the methane fermentation process with little additional energy and cost inputs. The aim of the study is to discuss the impact of selected pretreatment technologies of vegetable raw material plant for the production of biogas and to provide energy and economic balance of the proposed methods. Studies were conducted basing of foreign literature reports (in Poland not yet published research in the field of mechanical and thermal pre-treatment of plant biomass) and also based on knowledge and own research.
