Agglomeration of low rank Indian coal fines with an organic binder and the thermal behavior of the agglomerate produced: Part I

Thermal behaviour of low-rank Indian coal fines agglomerated with an organic binder

“…There has not been any work done on the decomposition behaviour of carbonized ACFs prepared by agglomeration of coal and an organic binder in an oxygen environment. However, the agglomeration of these coals with an organic binder and their preliminary thermal behaviour were reported in a previous study [21]. In continuation of the earlier work [21], the activation energy along with the other kinetics data of the decomposition of carbonized ACFs (i.e.…”

“…However, the agglomeration of these coals with an organic binder and their preliminary thermal behaviour were reported in a previous study [21]. In continuation of the earlier work [21], the activation energy along with the other kinetics data of the decomposition of carbonized ACFs (i.e. CNs) prepared is now studied using the isoconversional (model-free) kinetic methods (FWO and FR) [3,4,[22][23][24].…”

“…The size analysis (screen analysis) of the coal samples was already reported in our first part of this study [21]. The coal fines (size 0.211 mm) were mixed with different proportions of binders (molasses and carboxymethyl cellulose) and additive (lime) to prepare the green nodules by nodulizing in a disc-type nodulizer pan.…”

“…The carbonized ACFs (CNs) were prepared by using previously reported method [21]. The size analysis (screen analysis) of the coal samples was already reported in our first part of this study [21].…”

“…Many researchers have worked on the thermal decomposition of carbonaceous materials, including coals, under different environmental conditions [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. As stated in our previous report [21], the coals from Nagaland (India) have a lowash, high-volatile, high-sulphur contents and are mostly non-caking and swelling in nature. These coals are Electronic supplementary material The online version of this article (doi:10.1007/s10973-016-5564-x) contains supplementary material, which is available to authorized users.…”
