Present investigation focuses on the fractional conversion of low volatile weakly caking coal(LVWC)under the standard set of operating conditions for *** this purpose,samples of LVWC of different ash content have been collected from Kusunda Area of Bharat Coking Coal *** results were validated using Homogenous and Shrinking Core kinetic models and the suitability of selected samples for gasification was assessed by estimating the activation *** values of activation energy for LVWC samples were obtained in the range of 25.17-44.09 kJ/***,empirical models were developed to correlate the response of interest with the input variables(temperature,residence time and CO_(2) flow rate).The significance of these developed empirical models was checked using analysis of variance(ANOVA).

Effect of operating parameters on coal gasification

Coal combustion and gasification are the processes to utilize coal for production of electricity and many other applications. Global energy demand is increasing day by day. Coal is an abundant source of energy but not a reliable source as it results into high CO2 emissions. Energy industries are expected to decrease the CO2 emission to prevent global warming. Coal gasification is a process that reduces the CO2 emission and emerges as a clean coal technology. Coal gasification process is regulated by several operating parameters. A Number of investigations have been carried out in this direction. A critical review of the work done by several researchers in the field of coal gasification has been compiled in this paper. The effect of several operating parameters such as coal rank, temperature, pressure, porosity, reaction time and catalyst on gasification has been presented here.
