Combustion and Gasification are commercial processes of coal utilization, and therefore continuous improvement is needed for these applications. The difference between these processes is the reaction mechanism, in the case of combustion the reaction products are CO2 and H2O, whereas in the case of gasification the products are CO, H2 and CH4. In order to investigate these processes further, a s...

Biomass and coal gasification is a rapidly developing technology due to the increasing global demand for fossil fuel resources. Gasification is the process of conversion of solid carbonaceous feedstock to a gas mixture containing CO and H2 in the presence of steam or carbon dioxide. Past research on coal gasification has shown that the process requires high temperatures (> 800 oC) and produces ...

Underground Coal Gasification (UCG) is a process of converting coal in the ground into synthetic gas that has economic value. In UCG which will be carried out prototype assisted by presence oxygen as gasification agent, this agent help burning ground. The flow rate affecting combustion temperature and effective flame from coal. highest at 5 l/min 240oC, an 3 143oC 2 135oC time l / min ie 80 min...

In this paper, measurements of the CO2 gasification kinetics for two types of Shenfu coal chars, which were respectively prepared by slow and rapid pyrolysis at temperatures of 950 °C and 1,400 °C, were performed by an isothermal thermo-gravimetric analysis under ambient pressure and elevated temperature conditions. Simultaneously, the applicability of the kinetic model for the CO2 gasification...
