The Clean Coal Technology (CCT) Demonstration Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal utilization processes in a series of " showcase " facilities built across the country. These projects are on a scale sufficiently large to demonstrate commercial worthiness and to generate data for design, construction, operation, and technical/e...

INTRODUCTION The acid rain provisions of the 1990 Clean Air Act Amendments (CAAA) provide new incentives for the development of power generation technology with low SO 2 emissions. Detailed evaluations of possible NO x and air toxics emission limits also are required by the CAAA in the next few years. Furthermore, reauthorization of other key environmental legislation, such as the Clean Water A...

A test-rig closed-loop flotation column was used to observe the effect of diesel oil (collector) and Flomin F-425 (frother) on mass yield ash content for two Colombian coals: Caypa (northern zone) Guachinte (southwestern zone). The coal samples less than 38 µm (-400 M) were processed in a collector concentration range 0,32 1,60 kg/ton coal, as well frother 10 50 ppm. response surface methodolog...

Several technologies are being developed to convert coal into clean fuel for use in power generation. From the standpoint of component materials in these technologies, the environments created by coal conversion and their interactions with materials are of interest. Coal is a complex and relatively dirty fuel that contains varying amounts of sulfur and a substantial fraction of noncombustible m...
