Abstract | Co-gasification of non-woody biomass with char may induce a more stable gasification process and reduce tar and bed bridging. This paper presents a preliminary assessment of cotton gin waste-char i.e. coal co-gasification using air as the reactant. The influence of char addition in the mix of pellet fuel of cotton gin waste (CGW)-coal and gasification temperature are assessed using a thermodynamic equilibrium model. It is found that fuel compositions can significantly influence the performance and gasification products. Adding the coal can increase the syngas heating value, while increasing the gasification temperatures may lower the syngas heating value. At higher temperatures, the higher the coal ratio in the mix, the higher increment of syngas heating values. The drying and electricity energy need for a typical gin plant with the capacity of 40 bales/hour production is also assessed. The gin utilising CGW only pellet fuel may only be able to fulfil 69% of the energy required from its waste conversion to energy, while utilizing the mix of 20% coal in the pellet fuel can meet all its energy demand. |
