For example, Ishiwatari [11] investigated the thermal decomposition behavior by use of stepwise pyrolysis-gas chromatography for four oil shales (Colorado, Condor, Maoming and Timahdit oil shales from the USA, Australia, China and Morocco, respectively) and their kerogen concentrates.
The thermal decomposition behavior is an association of endothermic and exothermic effect.
A distinctive feature of the facility is that it uses cutting-edge thermal decomposition and gasification and reforming methods to melt waste at approximately 2,000C enabling all of the resources to be recovered.
