Fractionation of coal through organo-separative refining for enhancing its potential for the CO2-gasification

Abstract

Coal gasification has already been extensively studied earlier under varying conditions of steam, CO2, O2, 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 CO2-gasification in a fixed bed reactor under varying conditions. CO2 being an inert gas becomes the most challenging to be utilized during the gasification process. The SCCs showed better CO2-gasification reactivity than the raw Belbaid coal at 900 °C. The use of the catalyst K2CO3 tremendously increased the gasification reactivity for both raw coal and the SCCs. The use of sugarcane bagasse for CO2-gasification along with raw coal as well as with residual coal was also studied. Gasification under CO2 atmosphere conditions was used to structurally understand the coals as the coal structure gets loosened after extraction.

Diverse utilization of surfactants in coal-floatation for the sustainable development of clean coal production and environmental safety: a review

“…6–8 Specifically, huge amounts of solid waste such as ash are produced and toxic chemicals such as heavy metals, nitrate and sulphur are emitted during the direct incineration process of low-rank coal. 9–13 Also, excessive harmful gases such as NOx and SOx are also released during the production of electricity from low-rank coal, resulting in a further contribution to acid rain, skin problems, etc. 14–16 It is noteworthy to mention that over 10 Gt of CO 2 and about one-fifth of total greenhouse gases in the world are emitted each year due to the combustion of coal in power plants across the globe, making it the single largest cause of climate change.…”

“…Pourabdollah et al [35] studied the effect of thermal operation parameters against the graphitization of ethane-based catalytic coal. Dhawan et al [36] investigated the usage of the catalyst K 2 CO 3 over raw coal and the use of KCO 3 over the raw coal as well as help to extract the CO 2 gas from raw coal. Shukla et al [37] studied about the emission level of CO 2 in India from coal.…”
