Discussion on the advantages and disadvantages of using carbon dioxide as a gasification agent in gasifiers
Thread Content
Recently, I’ve often heard that using carbon dioxide as a gasifying agent or auxiliary can effectively increase the concentration of useful gaseous components. By adding carbon dioxide, it is possible to suppress the formation of carbon dioxide inside the furnace, thereby increasing the ratio of CO to H during the secondary reaction. Could someone provide a detailed explanation on this?
I believe carbon dioxide is produced as a result of combustion reactions; there are relatively few transformation reactions taking place inside the gasification furnace. Transformation reactions must occur under the action of a catalyst. If you’re considering a reaction between carbon dioxide and carbon directly, I suggest you look into the conditions required for such a reaction
Haha, back then someone suggested that burning lignite could raise the furnace temperature to 1800 degrees Celsius, which would generate a large amount of carbon dioxide; they even treated the vaporization furnace as a thermoelectric boiler – perfect for slag removal
