How is petroleum and coal formed?

Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.

What is the use of coal and petroleum?

These days, bitumen, a petroleum product, is used in place of coal-tar for metalling the roads. When heated in air, coal burns and produces mainly carbon dioxide gas. Coal is processed in industry to get some useful products such as coke, coal tar and coal gas.

Coal tar: It is obtained as a by-product in the process of making coke. Though its colour is the same as coke, tar is a highly viscous liquid.

Which is most green as fuel?

Biodiesel and bioethanol are the most common, viable alternatives and infinite green fuels that can be used in internal combustion engine. … The candidates as green fuels have the potential to significantly reduce the greenhouse gas emissions by as much as 30% from their combustion in internal combustion engine.

Petroleum refineries change crude oil into petroleum products for use as fuels for transportation, heating, paving roads, and generating electricity and as feedstocks for making chemicals.

What is coal made of naturally?

Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
