Optimization of coal pyrolysis modeling

Coal pyrolysis is complex, involving a large number of chemical reactions. The most accurate and up-to-date approach to modeling coal pyrolysis is to adopt the Distributed Activation Energy Model (DAEM), also called the Multiple Reaction Model (MRM). This can be very computationally expensive, since it involves a complicated multiple integration. A novel method of optimizing the mathematical modeling based on the DAEM has been developed. It has been shown that for a given accuracy, the method involves significantly less computational time than standard methods. Another advantage of the new method is that it allows errors to be estimated. (C) 2000 by The Combustion Institute.
