Abstract
Biomass wastes contain an abundant source of energy that can be transformed into high-calorific fuel during pyrolysis, consequently reducing the use of fossil fuel resources. Three types of biomass wastes were selected in this study: medium density fibreboard (MDF), brewery spent grains (BSG) and post-extraction soybean meal (SM). The studied feedstocks were analysed in detail in the range of ultimate and proximate analysis, chemical composition of ash, fibre analysis, and microstructure properties. MDF was a biomass with a high cellulose content (45%), hemicellulose content (46%) was predominant in BSG, while SM had low contents of cellulose, hemicellulose and lignin fibres (8%). The ash of MDF was characterized by titanium, calcium, sodium, and iron contents, while BSG and SM were typical agriculture biomass with significant potassium and phosphorus contents. FTIR analysis confirmed highly cellulosic structure of MDF. The intermediate pyrolysis of these wastes was carried out at 500°C temperature in a fixed-bed reactor under nitrogen atmosphere. Analysis of process yields has shown meaningful differences in pyrolysis product contents. Pyrolysis of MDF led to the main products such as char (25%) and aqueous phase (31%) whereas BSG oil (32%) was the main product. Elemental analysis demonstrated that MDF char had the highest carbon content. Generally, chars obtained from these feedstocks were characterized by a diverse internal microstructure. The surface of MDF char showed pores with a regular pattern of small perpendicular blocks. On the other hand, irregular open spaces were revealed in the BSG and SM chars. This investigation proved that biomass wastes are perspective feedstocks to obtain high-value bioenergy products.
