Fractionation of coal through organo-separative refining for enhancing its potential for the CO.sub.2-gasification

Coal gasification has already been extensively studied earlier under varying conditions of steam, CO.sub.2, O.sub.2, inert conditions. Belbaid coal and its e, N and NMP-DETA SCC products recovered through organo-refining under milder ambient pressure conditions were subjected to CO.sub.2-gasificatio...

Description
Summary:Coal gasification has already been extensively studied earlier under varying conditions of steam, CO.sub.2, O.sub.2, inert conditions. Belbaid coal and its e, N and NMP-DETA SCC products recovered through organo-refining under milder ambient pressure conditions were subjected to CO.sub.2-gasification in a fixed bed reactor under varying conditions. CO.sub.2 being an inert gas becomes the most challenging to be utilized during the gasification process. The SCCs showed better CO.sub.2-gasification reactivity than the raw Belbaid coal at 900 °C. The use of the catalyst K.sub.2CO.sub.3 tremendously increased the gasification reactivity for both raw coal and the SCCs. The use of sugarcane bagasse for CO.sub.2-gasification along with raw coal as well as with residual coal was also studied. Gasification under CO.sub.2 atmosphere conditions was used to structurally understand the coals as the coal structure gets loosened after extraction.
