Coal gasification is a valuable method in China to use coal effectively and cleanly. Coal is essential in China's energy production, so finding efficient ways to convert it is crucial. Current technologies involve converting coal into gas using different methods like fixed bed, fluidized bed, and entrained bed processes. These techniques aim to improve local coal resource utilization and reduce environmental impacts, leading to significant benefits for society and the economy. The future of coal gasification in China looks promising as these technologies evolve to make the most of the country's coal reserves.
