Coal preparation is a stage in the coal supply chain that follows mining but precedes shipment to the final end user. For many operations, runofmine coal consists of a composite mixture of carboniferous material and various noncoal impurities, such as rock, shale, clay, and water. Coal preparation, also denoted washing, cleaning, processing ...

In this study, coal fly ash was functionalized, using a simple onestep process (loading with Al3+ and sulfonation), to yield a solid acid catalyst (S/AlCFA) with strong acid sites. The catalyst was then used to produce furfural from xylose in a biphasic system (H2O(NaCl)/tetrahydrofuran). The furfural yield reached 82% at 180 °C60 min with catalyst/xylose ratio of : (w/w). With the ...
