Compilation of Sandia coal devolatilization data: Milestone report

Technical Report · Fri May 01 04:00:00 EDT 1992

OSTI ID:5100150

Fletcher, T H; Hardesty, D R

This is the first study in which single particle temperatures were measured during devolatilization in an entrained flow reactor. After publication of pyrolysis rates from the first set of experiments from the Sandia coal devolatilization laboratory, attention shifted to characterization of the chemical and physical properties of tar and char produced from different coals. This is the first set of detailed measurements of the chemical structure of coal char and tar formed during devolatilization at rapid heating conditions. These data provide a unique test of current devolatilization models, in that the correct volatiles yields must be obtained in addition to the correct chemical structure (and hence reaction mechanism).
