Abstract:
Gasification is a thermo-chemical process that produces syngas, which is a mixture of hydrogen, methane and carbon monoxide from coal or biomass. The proportions of this mixture is determined by, among other factors, the oxidizer used, which may include air, oxygen, steam or their mixtures in predetermined proportions. In this research, a mixture of oxygen and air was used to gasify coal from Mui Basin in Kenya, using fixed-bed dry-fed gasifier. When oxygen content in the oxidizing agent was varied between 21% - 100%, the optimum oxygen concentration was found to be 61%, at which the low heating value of the syngas was 12.98 MJ/m3 , and the cold gas efficiency was 75.2%. This research was aimed at enhancing the exploitation of Mui Basin coal for electricity generation for Kenyan citizens and to add to the wealth of knowledge on gasification technology.
