China to Invest US$15 Billion in Coal-to-Liquids Plants

China Oil News. The Chinese government plans to make a major investment of about US$15 billion in coal-to-liquids (CTL) plants (both direct and indirect) over the next 5 to 10 years as part of an effort to reduce dependency on oil imports.

The National Development and Reform Commission (NDRC) said that the combined output of the CTL plants could reach 16 million tons annually—about 320,000 barrels per day. That represents about 5% of China’s current oil consumption, and 10% of imports.

The plants will be located in coal-rich Shanxi, Shaanxi and Yunnan provinces, as well as Inner Mongolia Autonomous Region.

State-owned Shenhua Group, China’s largest coal company, announced in November 2005 that it had completed 30% of the construction of the first phase of its major coal-to-liquids project at the Shenfu Dongsheng coalfields in Inner Mongolia. Production is scheduled to begin in 2007, with initial output of approximately 1 million tons per year, or about 840,000 gallons per day. (Earlier post.)

Shenhua Group is also involved in a separate coal liquefaction feasibility study with Shell.

Indirect coal liquefaction first gasifies coal and then converts the coal-derived syngas into fuels and petrochemicals using Fischer-Tropsch technology. There are several technology and process alternatives for this type of approach to CTL.

Direct liquefaction, by contrast, breaks down the complex coal structure into smaller component molecules which then can be further refined into liquid fuel products by reducing the contents of sulfur and nitrogen.

Direct liquefaction conversion may have a slight edge in terms of process energy efficiency, according to some studies, but overall system efficiencies are basically comparable.

However, while some indirect liquefaction pathways (such as the production of dimethyl ether) may outperform fuels derived from crude oil with regard to both air-pollutant and greenhouse-gas emissions, direct liquefaction-derived fuels do not.




"reduce dependency on oil imports"

What they really mean is they don't expect they will be able to get enough oil via imports.
