the fly ash at the post-combustion zone. The environmental impact of the co-treatment of municipal solid waste incinerator (MSWI) fly ash with a combustible hazardous waste is lower than that of the thermal treatment of MSWI fly ash in a separate furnace (Huber et al., 2018b). Re-burning using the original incineration system is proposed

— Zeolite (FAZ) was synthesized by the fusion method using coal fly ash to adsorb carbon dioxide. The experimental adsorption was operated batchwise in a laboratory-scale packed-bed adsorber to obtain the breakthrough curves of CO2 under conditions such as adsorption temperatures (20–80 °C), flow rates of gaseous mixture of …
This paper describes improvements to a previously published technique for the extraction of carbonaceous fly-ash particles from sediments. By using test-tubes in a water-bath rather than beakers on a hot-plate, the number of simultaneous preparations that can be done is increased and the length of time spent on the preparations and the amounts of …
Among the publications were nine review papers, the first on the use of alkali activated fly ash ground granulated blast furnace slag to replace cement in concrete mix (Panda et al., Citation 2021), review of the potential utilization of CFA as a raw material for use in construction industry (Dwivedi & Jain, Citation 2014), the utilization of ...
— The extraction of metallic elements, such as Na, K, Ca, from the ash rapidly reached maximum value, and longer time contact of the ash with water could only reduce the extraction amount of some of the hazardous heavy metals (Table 1).For example, the extraction amount of Zn and Pb at 5 min was 20.2 and 3.48 mg l −1, compared to the …

— It can also be seen from Fig. 1 that silicon is inefficiently extracted in the extraction process, e.g., approximately 6% of silicon was extracted from the pre-treated ash by NTA under room conditions, and 2% was extracted in the SC water + NTA treatment. These results are consistent with a previous report (Hong et al., 2000).However, as …
