Thermal Co-conversion of Biomass, Sludge, and Coal

What is it about?

* Lignocellulosic biomass and sewage sludge are gaining attention as potential sources of clean and cheap energy to replace fossil fuels. * Combining these residues with coal can improve energy conversion processes, but there is a lack of concrete studies on the blending of these residues. * This review focuses on the thermal co-conversion of biomass/sewage sludge, coal/biomass, and coal/sewage sludge blends using thermogravimetric analysis (TGA). * The review explores the synergistic effects of composition, thermal conversion, and blending for bioenergy production. * It also provides information on operating conditions, properties, and chemical composition that can affect these processes and improve the yield of biofuels. * The study discusses influencing factors and possible decomposition mechanisms, and offers future prospects for the co-thermal conversion of biomass, sewage, coal, and their blends.
