A process investigation of the biosolubilisation of low rank coal in slurry system
The coal biosolubilisation processes may be used to convert low rank coal to either a clean, cost-effective energy source or to value-added products. This can lead to increased utilisation of low-rank coal. Low-rank coal is currently under-utilised because of its low calorific value, high moisture …

Processing of Low Rank Coal and Ultrafine Particle Processing by Hydrophobic-Hydrophilic Separation (HHS)
… processing of ultra-fine mineral particles and low rank coal using the hydrophobic--hydrophilic separation (HHS) method. Several explorative experimental tests have been carried out to study the effect of the various physical and chemical parameters on the HHS process. In this study, the HHS …

CFD study of the combustion of innovative fuels in blast furnaces for sustainable iron making
… renewable fuels to mitigate CO2 emission, and low-rank coal is regarded as flexible fuel to maintain the supply chain. Pulverised coal injection (PCI) technology has the readiness to accommodate these innovative fuels in ironmaking blast furnaces (BFs). However, the in-furnace phenomena of …

Sorption-Enhanced Hydrogen Production from Catalytic Steam Gasification of Coal
… CO2 emissions from fossil fuels. Clean coal technologies such as the calcium looping cycle show potential for capturing CO2. In this research, the thermodynamic and kinetic simulations of the CO2 capture process on calcium-based sorbent of calcined dolomite were investigated using Aspen …

The Phase Inversion-based Coal-CO₂ Slurry (PHICCOS) feeding system : design, coupled multiscale analysis, and technoeconomic assessment
… conveying of a solid feedstock like pulverized coal into a pressurized environment is a challenging task required in multiple industrial processes. Plants based on pressurized, entrained-flow gasifiers (EFG) are a good example. EFGs are used to produce synthetic gas for the production of …

The production of pure hydrogen with simultaneous capture of carbon dioxide
… energy generation from carbonaceous fuels, e.g. coal or biomass, necessary for the future. For hydrogen, an environmentally-benign energy vector whose sole combustion product is water, to become a major energy source, it must be produced in an efficient, CO2-neutral manner. A process, which uses …

Solute Transport Modelling of Latrobe Valley Ash Disposal Sites
… of solid wastes arising from the combustion of low-rank coal for electricity generation presents significant engineering and environmental challenges. The power stations in the Latrobe Valley region of Victoria, Australia, have long recognised the need for improved long term understanding of ash …
