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).

Coal Processing is a term that is used to designate the various operations performed on the ROM coal to prepare it for specific end uses such as feed to a coke oven or a coalfired boiler or to a coal conversion process without destroying the physical identity of the coal. Coal Processing is recognized as a combination of science, art and ...

Critical metallic elements in coal gangue have great utilization potential, especially due to the current shortage of these metals. This paper focused on examining the feasibility of physical separation (screening and floatsink tests) and calcination treatment for the enrichment of critical elements (Li, Ga, and rare earth elements plus yttrium (REY)) from coal gangue.

A middle/lowtemperature coal tar (M/LTCT) was obtained from a lowtemperature carbonization plant in Shaanxi, China. The M/LTCT was separated into light components and coal tar pitch through extraction. A series of alkanes, aromatic hydrocarbons, oxygencontaining arenes (OCAs), and nitrogencontaining arenes were fractionated from light components by mediumpressure preparative ...
