Co-gasification reactivity of petroleum coke with coal and ...

Feb 01, 2020  It was found that the synergetic effect can be enhanced with increasing coal proportion. However, as the increase of coal rank, the synergetic effect gradually weakened during the co-gasification process. In the selected coal/CLR samples, the low rank coal and CLR exhibited a better effect when co-gasifying with petroleum coke.
