J. Cent. South Univ. (2017) 24: 30-38 DOI: 10.1007/s11771-017-3405-0 Adsorption of residual amine collector HAY from aqueous solution by refined carbon from coal fly ash and activated carbon LI Xian... from coal fly ash (CFA) as well as powdered activated carbon (PAC) was investigated as adsorbent to remove residual amine collector HAY from aqueous solution. The RC and PAC were characterized......
J. Cent. South Univ. (2018) 25: 9-20 DOI: https://doi.org/10.1007/s11771-018-3712-0 Microwave digestion and alkali fusion assisted hydrothermal synthesis of zeolite from coal fly ash for enhanced... hydrothermal method was proposed to synthesize zeolite from coal fly ash and the zeolite product was studied for removal of Cd(II) from aqueous solution through batch experiments. The adsorbent......
Pozzolanic Reaction Kinetics of Coal Ashes郑洪伟,钱觉时摘 要:The pozzolanic reactivity was determined by the hydration kinetics of pozzolanic reaction based on the fact that the hydration products of active SiO2 and Al2O3 with lime were soluble in dilute hydrochloric acid. The results show that the pozzolanic reaction of active SiO2 and Al2O3 of coal ashes......
concentrates(PTC)briquette containing coal under argon atmosphere was investigated by thermogravimetry in an electric resistance furnace within the temperature range of 1250-1350°C.The samples reduced in argon... that the reduction of PTC by coal depends greatly on the temperature.At high temperatures,the reduction degree reaches high values faster and the final value achieved is higher than at low temperatures.The......
