Underground Coal Gasification (UCG) is a process in which coal is converted to syngas in-situ. UCG has gained popularity recently as it could be used to extract energy of deep-lying coal seams, and it reduces the footprints attributed to the gasification process. In this study, two models have...

During the past few decades, petroleum has been the main source of liquid fuels. On one hand petroleum reserves are declining, and on the other hand coal reserve is the most abundant fossil fuel known in the world. Liquefaction aims to convert solid coal into liquid fuels. Coal can be converted...

Metallurgical coke, a porous carbon material produced by carbonization of coking coal at high temperature, generally above 900 ○C, is an integral part of iron-making in the blast furnace. During iron making, coke serves several important roles in the blast furnace such as a source of energy, as a...

The fragmentation of large coal particles at high temperature is important to the efficient operation of Corex process of steelmaking, which uses raw coal instead of coke. The hypothesis is that the heterogeneity within coal particles affects the fragmentation. The interface of minerals and coal...
