The general objective of this study is to define and quantify the relationships between coal composition and structure and associated combustion and conversion behavior for three very different domestic coals of interest. To accomplish this objective, two tasks have been identified. The first is to characterize the virgin coal and the process chars. This will give the necessary information to determine if the char preparation process yields or rates are dependent on coal physical and chemical characteristics. The second task is to measure high temperature reaction rates of the virgin coals and their derived chars, and to interpret results in light of Task 1. During the past quarter, design of the high-temperature reactivity facility was completed for the optical and furnace systems. The designs of these systems are discussed. Proximate analyses were continued and results are presented. The system transfer function for the optical system is computed and found to be a function of one arbitrary constant and physical characteristics of the lenses used. The radiant emission of the optical system is a function of the brightness of the object imaging the system. Plans are also presented for the following quarterly period. 9 refs., 5 figs., 1 tab.
