11. The catalyst was created by carbonization of simple sugars such as glucose and sucrose. 12. The walls and roof retain enough heat to initiate carbonization of the next charge. 13. When wood is heated above 270 �C it begins a process of decomposition called carbonization . 14. Carbonization starts and produces volatile matter, which burns inside the partially closed side door.15. Carbonization and graphitization are the two processes responsible for this alignment of the crystalline regions.16. As coal contains mainly carbon, the conversion of dead vegetation into coal is called carbonization . 17. The gas produced by carbonization has a high content of carbon monoxide which is poisonous when breathed. 18. Although carbonization of CO has been reported at temperatures above 350? it is rather a rare phenomenon. 19. The technology was primitive carbonization and Distilled shale oil and oil shale gas were collected through perforated pipes. 20. By observing the smoke exiting the kiln, the charcoal burner could assess the state of the carbonization process.
