摘要: Coal pyrolysis is complex process that includes many small reactions. Being complicated, it difficult to study the mechanism with high rank coal directly. Peat a rudimentary which has most simple structure lower polymerization. Some researchers think key understanding in an appreciation of molecular components original peat swamp and how these might be modified. It generally agreed chemical diversity various coals will affect rate combustion through devolatilization process. Upon heating, some bonds undergo cracking result release light gases production tar. Through analysis best model compound coal, basic step reactions can understood. The objective this analyze using in-situ pyrolysis-FTIR establish model. results show during rapid pyrolysis, all functional groups produced have almost same activity energy; difference among them degree reaction.
