Abstract
A new carbonization process with high temperature preheating has been studi ed. A mechanism which improve the coking property was examined with coal pr operties by Solid State NMR and NMR imaging methods. It has been clarified that the molecular structure of coal has been relaxed by the rapid heating treatment and addition there is a close relation in hydrogen bond and relax ation of molecular structure of coal. Furthermore, the specimen of coal sho w the increase of mobile component by the rapid heat treatment using NMR mi cro imaging.
