China has rich coal resources but lacks oil and gas; the coaltoliquids (CTL) technology rose as a consequence of increasing oil price, but regulators suspended new projects in 2008 after oil prices retreated and concerns ...
The conversion of synthesis gas to liquid molar fuels by means of a cobalt FischerTropsch catalyst composition is enhanced by the addition of molybdenum, tungsten or a combination thereof as an additional component of said composition. The presence of the additive component increases the olefinic content of the hydrocarbon products produced.
Other approaches to converting carbon dioxide into fuel, Li explains, usually involve a twostage process: First the gas is chemically captured and turned into a solid form as calcium carbonate, then later that material is heated to drive off the carbon dioxide and convert it to a fuel feedstock such as carbon monoxide.

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 ...
