This experimental study investigates the impact of different silica-to-alumina (Si/Al) ratios on geopolymers synthesized from metakaolin. Various ratios of Si/Al (1 : 1, 1.5 : 1, 2 : 1, 3 : 1, 4 : 1, and 5 : 1) were employed, nano-silica was the source material to alter the ...
This study is focused on developing an improved understanding of liquid flows in the lower zone of the blast furnace. To this end, two experimental methods have been developed in which the molten slag flow through a laboratory scale coke bed and the flow through a narrow channel in coke are...

Although air combustion can restore the catalytic activity, the introduction of aromatic C=Osp2species, on the contrary, will eventually accelerate the catalyst deactivation21,33. Hydrogen may be a potential candidate34,35, however, the activation energy of hydrogenation reaction of PAHs (e.g., ph...
effect of AC.The technical and economic characteristics of this process were introduced.Based on CFX numerical modeling software,several factors and relevant suggestions were studied and proposed,including the flow field,the desulfurization efficiency and the resistance features inside the desulfurization ...
The X-ray diffraction (XRD) pattern of HAP-Ce evidenced no crystalline CeO2phases (Supplementary Fig.2a), suggesting that cerium is either highly dispersed on the HAP external surface or doped into the lattice. Ni and NiO reflections were also absent from all unreduced samples (Supplementary Fi...
Due to its low cost, easy processing, great performance, low energy consumption, and ability to produce treated wastewater of the highest quality on a small- and large-scale without secondary pollution, adsorption has grown in popularity among environmentalists16,17. Many adsorbent materials ...
