Studies on the CO2 adsorption mechanism of Na-X and Na-Ca-X coal fly ash zeolites

(Corresponding) Boycheva S., Lazarova H., Zgureva D., Popova M.

Topic:

Climate change mitigation and adaptation

Coal fly ash zeolites (CFAZ) of Na-X and Na-Ca-X types were synthesized using as raw materials fly ashes generated by the combustion of lignite from various deposits with low and medium limestone content. It has been found that CFAZs with higher calcium content superior those containing less...Read more

Studies on the CO2 adsorption onto coal fly ash zeolites at elevated pressures

(Corresponding) Boycheva S., Zgureva D.

Topic:

Climate change mitigation and adaptation

Coal fly ash zeolites (CFAZs) of Na-X type were prepared by ultrasonic-assisted double stage fusion-hydrothermal synthesis from lignite coal fly ash at two different fusion temperatures 550 and 800 C. The detailed surface analyses were performed experimentally using N2 physisorption technique and...Read more
