The article explores how different factors affect coal gasification, a process that turns coal into cleaner fuel, reducing harmful CO2 emissions. Researchers reviewed many studies on this topic to understand how variables like coal type, temperature, pressure, and time impact the gasification process. They also looked at how catalysts and porosity influence the reaction. Their findings show that these factors play a significant role in determining the efficiency and environmental impact of coal gasification, which is crucial for reducing CO2 emissions and combating global warming.
