Effective Removal of Fe and Ca From Coal Fly Ash for High‐Purity and High‐Surface‐Area Zeolite X Synthesis: A Comparative Study of Acid Refluxing and Acid Roasting Methods

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
Coal fly ash (CFA) is an abundant industrial waste rich in silica and alumina and represents a viable feedstock for zeolite synthesis; however, high levels of calcium and iron limit zeolite purity and crystallisation. This study evaluates acid refluxing and acid roasting as pre‐treatment strategies for the simultaneous removal of Ca and Fe from high ...

Coal desulfurization [PDF]

open access: yes, 1979
Organic sulfur is removed from coal by treatment with an organic solution of iron pentacarbonyl. Organic sulfur compounds can be removed by reaction of the iron pentacarbonyl with coal to generate CO and COS off-gases.

Thixotropy of highly loaded coal-water slurries.

open access: yesJOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1984
For the better preparation of highly loaded coal-water slurries in coal utilization processes, the thixotropic behavior of CWM was simulated by means of a new thixotropy model employing the yield stress as a structural parameter. Ways to imrpove the slurry preparation method were studied by combining the experimental results of thixotropy and stability

Aerated atomization of coal-water slurry fuels [PDF]

open access: yes, 1988
In order to observe the effects of rheology on the atomization of highly viscous non-Newtonian liquids, glycerin-water solutions and cellulose-glycerin-water solutions have been atomized. In this series of tests, nozzle pressure, air-liquid ratio and liquid viscosity were altered, and the effects were observed. 14 figs.
