What is coal pyrolysis: coal pyrolysis involves subjecting coal to high temperature of 400-450°C, in the absence of oxygen. When oxygen or steam is present, coal will start burning, and the process is no longer known as pyrolysis but rather referred as combustion and gasification. The benefits of coal pyrolysis are enormous and are listed below:
