Carbonization is the conversion of any organic matter into carbon, for many different processes. Pyrolysis is the chemical decomposition of organic matter in the absence of oxygen. And graphitization is the conversion process of carbon into graphite, is mostly used in metallurgy but can be done in other fields
Hi dear Linto, in both gas and carbon analysis methods, you use heating materials in an inert environment. This is the fundamental similarity between these two processes I think. Pyrolysis is intended to extract valuable products from materials. Carbonization, on the other hand, is intended to increase surface area.
And about Graphitization, as far as I know, it's a method to produce higher modulus fibers with Grade (HM) and UHM extra heat is carried out in the vicinity of inert gas at 2500 to 3000 ° C.
Rafael Valentin Tolentino-Hernandez . I agree with your statement. But Pyrolysis also increases the carbon yield same as carbonization. Also Pyrolysis helps to extract the material through decomposition. I need some more good explanations to verify. Don't copy paste internet articles please.
