Partial oxidation of methane over biomass fly ash (BFA)-supported Ni/CaO catalyst for hydrogen-rich syngas production

Biomass fly ash as nanofiller to improve the dielectric properties of low-density polyethylene for possible high-voltage applications

“…2 (b), which corresponds to different metal oxides. The detailed XRD analysis of BFA is reported elsewhere [ 30 ]. In brief, the SiO 2 and Fe 2 O 3 peaks appeared at 2θ = 26.5° (PDF# 46–1045) and 32.8° (PDF# 10–0653) with index values of (101) and (420) respectively [ 30 ].…”

“…A waste material of biomass-fired power plants known as biomass fly ash (BFA) include several metal oxides, including CaO, Fe 2 O 3 , MgO, Al 2 O 3 , and SiO 2 [ 28 ]. BFA is a fine nanopowder with a versatile chemical composition that makes it an attractive nanofiller [ 29 ][ 30 ]. It has the ability to disperse more effectively in LDPE and enhance the dielectric properties of LDPE loaded with BFA (BFA-LDPE).…”

Emerging trends in the recovery of ferrospheres and plerospheres from coal fly ash waste and their emerging applications in environmental cleanup

“…Ferrospheres extracted from CFA are chemically diverse due to the presence of Fe, Si, Al, C, K, Ca, Mg, etc., and are suitable for various applications, especially as catalysts in the petroleum industry, mainly in the high-temperature process of based oxidative dimerization of methane (Alterary and Marei, 2021;Naeem et al, 2022). FS are used frequently used in metallurgy for the extraction of pure iron particles.…”
