Background and unmet needs

  Anthracite coal is a principal source of metallurgical coke, and is a preferred domestic and commercial solid fuel due to its consistent size and hardness of lumps, very high carbon content, high heating value, low volatility, low ash, and especially low sulfur content. The value of anthracite as a fuel is particularly enhanced by its uncontrolled low sulfur stack gas emission. Anthracite is the solid fuel of choice in the United States, and, more often, in the Far East, for certain space heating, cooking, stoker boiler, and metallurgical uses. Naturally-occurring clean-burning solid fuels such as wood, charcoal, and anthracite have limited availability in most parts of the world. Meanwhile, environment pollutions are world-wide concerns and there is need for new non-petroleum and low-carbon energy with low price fuels in energy industry. and there is a need of recycling of agricultural waste to clear environment.
