Effect of Ash Composition (Ca, Fe, and Ni) on Petroleum Coke Ash Fusibility

Ash fusion behavior is closely associated with ash-related problems including fouling, sintering, and slagging, which results in a negative effect on the utilization of petroleum coke (petcoke). Petcoke ash contains high levels of vanadium (V), nickel (Ni), iron (Fe), and calcium (Ca). The chemical composition of ash plays an intrinsic role in determining ash fusibility. To better understand the modification mechanism of the ash fusion...
