1. General: Coal resources and use
China has the world’s third largest coal resources. According to the China Coal Industry Yearbook 1996, estimates for coal resources are 5500 billion tons, although much of these resources are probably not recoverable. China has about 11% of the world’s recoverable reserves with 115 billion tons, with 55% classified as bituminous (including anthracite), 29% as sub-bituminous and 16% lignite. Over 80% of China’s coal reserves are concentrated in the north and northwest in the country.

Coal combustion products
纳米盘链接Coal combustion products
The working definition for solid materials resulting from the combustion of coal has been evolving. Environmental regulators first used the term “coal combustion wastes”. Later, the term coal combustion byproducts gained popularity. Lately, “coal combustion products (CCPs)” has become a household term for those in the power industry, the ash marketers, and most users of these materials.

Conceptually, coal gasification is a relatively simply process. A carbonaceous fuel-usually coal, petroleum coke, or heavy oil-is co-fed with water and oxygen in a reducing atmosphere at high pressure (up to 1,000 psig) to produce the desired products of carbon monoxide (CO) and hydrogen (H2). Sulfur in the form of H2S and some amount of CO2 is also produced and removed in the process. This gaseous mixture is commonly referred to as synthesis gas or syngas. Commercial gasifiers differ widely in the way in which they produce ash, either a dry ash, an agglomerated ash, or slag may result. The Lurgi and other fixed-bed gasifiers operate by passing ......
