Abstract. Development of renewable energy is essential to mitigating the fossil fuel shortage and climate change issues. Here, we propose to produce a new type of energy, biocoal, via a fast pyrolysis coupled with atmospheric distillation process. The high heating values of the asprepared biocoals from the representative biomass are within ...

India's argument is that it is unfair to single out coal which is primarily used by developing countries while other fossil fuels widely used in western countries remain unsanctioned.
Formation of Coal (Process) Coal is composed of carbon, hydrogen, oxygen, nitrogen, sulphur, moisture, and incombustible mineral matter (, ash). Fluorinated gases are not formed by coal combustion. Coals are formed from the accumulation of vegetable debris in specialized environments. Obtaining coal from the mines is a difficult job.

The coal reserves in India are some of the largest in the world (5th biggest reserve). Most of the coal deposits in India is of the bituminous type. These are mostly noncoking coal. This is the reason for our import dependence in the sector. Most of the coal deposits in India is of the Gondwana type (about 99%).
Uses of Coal. It is mainly used to generate heat and electricity. It is used in households and in industries to accomplish various tasks. It is the cheapest source of power fuel. The iron and steel industry depends heavily on fossil fuel for energy. It is also used to produce useful products such as coke, tar, and coal gas.
Coal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about billion tonnes in 2010 ( billion short tons) and is expected to increase 48% to billion tonnes ( billion short tons) by 2030.. China produced billion tonnes ( billion short tons) in 2011.
Metallurgical coal is an essential ingredient in the production of steel, making it one of the most widely used building materials on earth.
