Carbon and Fossil Fuels

Burning of biomass fuels produce methane

Smoke contains carbon particles which are solid, so smoke is a solid - in - gas mixture.

Coal is the most polluting as it releases the maximum amount of solid particulates into the air and also leaves behind a residue after burning.

Charcoal is left behind; water and volatile material get removed.

High calorific value and ease of transport are the characteristics of a good fuel. 

Carbonisation is the term for the conversion of an organic substance into carbon or a carbon-containing residue through paralysis or destructive distillation.

Kerosene oil is used as fuel for stoves, lamps and for jet aircrafts.

Magnetite is an ore of iron. 

Naphthalene balls are obtained from petroleum by fractional distillation.

Anthracite is the highest rank of coal. It has a carbon content of over 87% on a dry ash-free basis.

Natural gas is stored under high pressure as compressed natural gas (CNG). CNG is used for power generation. It is now being used as a fuel for transport vehicles because it is less polluting. It is a cleaner fuel.

Coal gas is obtained during the processing of coal to get coke. It is used as a fuel in many industries situated near the coal processing plants.

Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.

Coke is a tough, porous and black substance. It is almost pure form of carbon. Coke is used in the manufacture of steel and in the extraction of many metals.

Natural gas is the purest fuel, which burns completely in air to produce large amount of energy and no smoke is produced.
