Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

A future alternative to conventional petroleum could be liquid fuels made from coal. The technique is called coal liquefaction. From 1 to 3 barrels of oil can be made from each ton of coal. The basic technology is known; the major obstacles in the US have been the high costs of the synthetic oil and the risks of building large, multibillion ...

Petroleum is an ingredient in thousands of everyday items. The gasoline that we depend on for transportation to school, work, or vacation comes from crude oil. A barrel of petroleum produces about 72 liters (19 gallons) of gasoline, and is used by people all over the world to power cars, boats, jets, and scooters.

The FischerTropsch process is a catalytic chemical reaction in which carbon monoxide (CO) and hydrogen (H 2) in the syngas are converted into hydrocarbons of various molecular weights according to the following equation: (2n+1) H 2 + n CO → C n H (2n+2) + n H 2 O. Where n is an integer. Thus, for n=1, the reaction represents the formation of ...
