GASIFICATION • Gasification is a process that converts organic or fossil fuel based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide. This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam. The resulting gas mixture is called syngas ...

3. Coal briquetting is a process which converts coking coal slack into uniform usually hard and impact resistance agglomeration, making it useful with high calorific value for domestic industrial purpose. Coal import can be very expenses in some instances it accounts upto 70% of delivered cost of coal. The first patent for the briquetting of coal fines dates back to the mid1800s.
