Coal To Liquids Conversion Technique
« on: 22/12/2008 09:16:27 »
Linc Energy has entered into a Memorandum of Agreement with Syntroleum Corporation (USA), one of the world leaders in Coal To Liquids (CTL), whereby Linc has access to their CTL technology. Syntroleum has designed, built and currently operates a CTL plant in Tulsa, Oklahoma using its unique air based CTL process.

CTL is the generic term used to describe the process of converting a gas into a liquid hydrocarbon product. This technology has already been tested and proven by numerous companies including major oil companies. The combination of UCG and CTL is subsequently called Coal to Liquids (CTL), as the initial energy source is coal.

Basically, a CTL plant consists of three main processes:

Syngas Production: this process converts a solid, liquid or gas feedstock (usually natural gas) into hydrogen and carbon monoxide.

UCG syngas is already a mix of hydrogen and carbon monoxide, therefore this first process does not apply to Linc Energy.

Fischer-Tropsch (F-T) Synthesis: it is the heart of the process. The syngas is converted into liquid hydrocarbons, through a catalytic reaction using cobalt as catalyst. The syngas reacts with the cobalt, joining together simpler hydrocarbon chains contained in the gas, to create a longer liquid hydrocarbon chain (syncrude).

Refining: the liquid hydrocarbon is then filtered and refined to produce the end product fuels: LPG, Naphtha, Jet fuel and Diesel.

These end products are essentially free of sulphur, olefins, metals, alcohols and aromatics. CTL liquid fuels are superior to conventional refinery fuels.

As a part of its ongoing CTL R&D program, F-T trials have been performed at the University of Kentucky's Centre of Applied Energy Research (CAER). A similar syngas composition to the one produced at Chinchilla is being used as feedstock to determine the best catalyst, operating temperature, pressure and other variables.

After having successfully produced diesel at the University of Kentucky Linc Energy strongly believes that the partnership with Syntroleum will enhance and expedite the development of Linc Energy as a leading ultra-clean diesel producer.

Well, there's nothing new about FT

At heart it turns coal into stuff that gets burned and produces CO2 which is widely thought to contribute to global warming.
While it offers some "cleanup" of the original coal - for example stripping out sulphur- it's not really that clean a technology.
It may produce ultra clean diesel, but so does biodiesel and, in principle, that can be carbon neutral.
No technology based on coal can currently do that.
