Abstract
The present work provides a comparison of waste blends utilized as feedstock in a fixed bed gasifier for synthesis gas production. The residues analyzed were polymeric wastes, electric and electronic equipment, wood wastes, residues derived fuel, plastics and rubber, and waste tires. A comparison of the characterization of these residues was performed in terms of their proximate analysis presenting moisture content, volatile matter, fixed carbon, ashes, higher heating value and ultimate analysis regarding the percent of Nitrogen, Carbon, Hydrogen, Sulphur and Oxygen in the raw materials. The gasification and co-gasification of these materials were analyzed in terms of operating parameters such as oxidation and reduction temperatures, feeding rate, air and syngas flows, and tars and chars production. Further, the main comparison parameter analyzed was the Lower Heating Value of the produced gas as well as its composition. The average values of the Lower Heating Value of syngas ranged from 3.0 to 5.4 MJ/m3 while the chemical composition of the gas had nearly 12% of hydrogen, 20% of carbon monoxide, 3% of methane, 10% of carbon dioxide, and around 55% of nitrogen. The co-gasification of biomasses with materials typically found on municipal solid waste may result in high-quality syngas that can be used for decentralized energy generation.
