CoaltoLiquids. CoaltoLiquids (CTL) is a process of converting coal to fuels such as diesel or gas. For diesel, the process involves first building a plant to convert coal to gas and then another plant to covert the gas to a liquid. The resultant liquid fuel is known as synthetic fuel or synfuel. Synfuels are used as an alternative to oil ...

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 ...

The total expenditure of energy in the world each year is about 3 × 10 17 kJ. Today, more than 80% of this energy is provided by the combustion of fossil fuels: oil, coal, and natural gas (The sources of the energy consumed in the United States in 2009 are shown in Figure ) but as Table from the Wikipedia shows, energy usage is a complex issue.

One means of converting coal to an alternate form of energy is gasification. In this process, coal is combined with oxygen and steam to produce a combustible gas, waste gases, char, and ash. The more than 70 coal gasification systems available or being developed in 1979 can be classified by

Then, the gas is turned into a liquid that is used as fuel. This is done most often through the FischerTropsch process, which involves chemically refining the syngas to eliminate impurities, including sulfur and nitrogen, and converting it into either gasoline or diesel. This fuel is said to be cleaner than gasoline because it is sulfurfree.

Coal gasification means the complete conversion of coal into gas using heterogeneous gas solid reactions. The main process is the reaction of the carbon of coal with steam, at pressures below 10 MPa and temperatures above 750°C, to form a "synthesis gas" containing mainly CO and H 2 with smaller amounts of CO 2 and CH 4, depending on ...

Answer Explanation. All tutors are evaluated by Course Hero as an expert in their subject area. Liquefaction is the process of converting solid coal into liquid fuels. The main difference between naturally occurring petroleum fuels and coal is the deficiency of hydrogen in the latter: coal contains only about half the amount found in petroleum.

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.
