Abstract
Gasification of fine coal waste as waste still produces unavoidable by-products, namely charcoal. The utilization of fine coal and its potential should be advanced to reduce the waste and improve the quality of the synthesis gas produced. The objective of this study is to produce syngas with the addition of fine charcoal to improve the quality of the syngas. Gasification is carried out in a fixed bed reactor at 550-800 °C with different proportions of charcoal. The quality of the syngas was evaluated based on the composition of H2/CO syngas, LHV and gasification efficiency. The results showed that a 50:50 ratio produced a syngas with 45.24 vol% CO2 and 41.38 vol% H2 at 800 °C. Increasing the ratio not only stabilized the heating value gain (~13 MJ/Nm3), but also increased the carbon conversion by > 90%. Alkali and alkaline earth metals (Ca, K, Fe, Mg and Mn) favor the Boudouard reaction to produce CO.
