Quantification of persistent free radicals (PFRs) formed in thermally decomposed cellulose and its correlation with residual carbon amount

Thermal decomposition of cellulose was carried out in a tubular reactor under flowing argon gas at 573, 673 and 773 K. The loss of carbon, hydrogen and oxygen was observed, and enhanced with increase in temperature continuously. The persistent free radicals (PFRs) were not observed in the sample dec...

The loss of carbon, hydrogen and oxygen was observed, and enhanced with increase in temperature continuously. The persistent free radicals (PFRs) were not observed in the sample decomposed at the lowest temperature of 573 K, and observed in the samples decomposed at higher temperatures of 673 and 773 K.
