Management of coal waste by energy recovery: mild gasification/flash pyrolysis of coal preparation wastes. Quarterly report No. 1, October-December 1984
UCC Research Corporation, along with most of the companies involved in coal development, initially was thinking in terms of high pressure systems, flash pyrolysis, and hydrogenation. Most goverment funding has also been provided for projects using these techniques. However, information from several sources, only recently available to UCC Research Corporation, has effected a change in our recommended direction on the subject project. First, information being obtained in-house at UCC Research on another project using low temperature/pressure pyrolysis looked very favorable. Secondly, the initial review of the design, cost and capabilities of the pyrolysis equipment originally proposed indicated that substantial advantages could be gained at only a modest increase in cost, by changing to a low pressure unit. Finally, it was discovered that a company in England, using almost identical pyrolysis conditions as those being used at UCC Research, was producing coal liquids commercially, and had been in business many years. In consideration of the above information, UCC Research is recommending that the pyrolysis system for the subject project be changed to a low pressure/temperature design, utilizing the information obtained via our in-house research and from the company in England.
