Gasification of char from wastewater solids pyrolysis
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.
