[Gasification] Coke and Char

[ktwu at itri.org.tw]

Dear all

Merry Christmas and Happy New Year! 

What is difference between coke and char? Coke from coal and char from biomass? And what's about soot?

According to Franklin's research in 1950s, she mentioned that while the cokes could be graphitized by heat treatments above about 2200 deg-C, the chars could not be transformed into crystalline graphite, even at 3000 deg-C.

Franklin, R.E., "Crystallite growth in graphitizing and non-graphitizing carbons", Proc. Roy. Soc., A209, 196-218 (1951).

However, any definition we can describe easily, not carry out test after getting the sample?

Thank you very much indeed.

All the best in 2012
