Abstract
Present investigation focuses on the fractional conversion of low volatile weakly caking coal (LVWC) under the standard set of operating conditions for gasification. For this purpose, samples of LVWC of different ash content have been collected from Kusunda Area of Bharat Coking Coal Ltd. Gasification results were validated using Homogenous and Shrinking Core kinetic models and the suitability of selected samples for gasification was assessed by estimating the activation energy. The values of activation energy for LVWC samples were obtained in the range of 25.17–44.09 kJ/mol. Further, empirical models were developed to correlate the response of interest with the input variables (temperature, residence time and CO2 flow rate). The significance of these developed empirical models was checked using analysis of variance (ANOVA).
