Effects of Different Solvents on Co-gasification of Can Lignite with Sorghum Biomass

Acelya Secer


In this study, a mixture of sorghum biomass and Çan lignite, containing 25% sorghum, was gasified at operating temperatures of 700 ° C and 900 ° C using tetrahydrofuran (THF), dimethylformamide (DMF), methanol, xylene, tetralin and acetone solvents as gasifications agent. The effect of the use of other solvents instead of water as the gasifying agent on the gasification performance was evaluated in terms of the total gas volume produced, the hydrogen gas content of the product gas and the distribution of other gases in the product gas. At operating temperature of 700 ° C, the total gas volume and hydrogen gas production produced were greater than that of water for all solvents. Methanol was the solvent that provides the highest gasification efficiency at 700 ° C. At the operating temperature of 900 ° C, the highest gasification yields were obtained with THF, DMF and methanol solvents, respectively. The most effective gasifying agent at this temperature was THF with a total gas volume of 3650 mL and a volume of hydrogen gas of 2478 mL.
