Abstract:

Batch experiments were carried out to evaluate the effects of reaction temperature, reaction time, and char-to-steam ratio on the gasification of char from wastewater solids pyrolysis. The batch experiments revealed that more than 97% volatile solids reduction efficiency can be attained by maintaining reaction temperature at 950 to 1 000°C, reaction time at 30 minutes, and char-to-steam ratio at 1:10. The increase in reaction temperature resulted in a reduction in hydrogen-to-carbon monoxide (H₂/CO) and carbon dioxide-to-carbon monoxide (CO₂/CO) ratios, suggesting that the carbon-steam reaction reaches equilibrium at 800°C and higher. However, the Boudourd reaction continued to progress toward more product formation with the increase in temperature.
