A PROCESS FOR THE MANUFACTURE OF COKE FROM COAL WITH IMPROVED CRI AND CSR VALUES BY EARLY CATALYTIC DEVOLATILISATION. |
摘要 |
<p>A process for producing coke with improved CRI and CSR and with minimum porosity by faster devolatilisation at the fluidic state of coal blends. The advancement identifies and provides for a possible way to achieve such faster devolatilization by involving variety of devolatilisation catalysts including divalent and multivalent metal oxides which can be reduced at lower temperatures favouring a cost effective process for producing coke from coals/coal blend including even non-coking coal and reduced quantity of costly and scarce hard coking coal. Importantly, the process of catalytic devolatilisation of coal/coal blend enable achieving one hand superior quality coke with decrease in CRI to an extent of 1.0-3.5% and an increase in CSR to an extent of 1.0-3.5 % at less cost and on the other hand reduce the carbonization completion time by 3% and thus improving the coke oven productivity by about 3%, making the process useful for industrial application.</p> |
