The lignin-derived phenolic compounds present in lignocellulosic hydrolysate might have an adverse impact on acetone-butanol-ethanol (ABE) production by Clostridium beijerinckii ZL01. In this study six model phenolic compounds including 4-hydroxybenzaldehyde, 4-hydroxybenzoic acid, vanillin, vanillic acid, syringaldehyde, and syringic acid were eva...

The removal of SiC restricts the recycling of silicon from wire sawing waste. Although the silicon in sawing waste can be easily enriched to around 90 wt%, it is difficult to further increase the purity. In this study, silicon ingot was successfully recovered from silicon sawing waste by using a CaO-SiO2-Na2O slag refining method. CaO-SiO2 slag was...

Novel high temperature-resistant thermal barrier coatings are urgently required as the stringent operating environment. High temperature property studies of zirconia matrix thermal barrier coatings doped with Cr3+, Mg2+, Si4+, and Mn4+ ions prepared by solid phase reaction method are reported. The results of X-ray diffraction measurements prove the...

The process of neutralization of stainless steel pickling wastewater will produce a lot of pickling sludge, and improper treatment of this sludge poses a serious threat to the environment. This paper presents a new process for disposing stainless steel pickling sludge in an environmentally friendly manner while effectively reusing the elements cont...

In this study, we put forward a clean and complete process of V2O5 production from vanadiumcontaining solutions. It features membrane electrolysis for V/Na separation and AMV precipitation. With the aid of membrane electrolysis, the vanadium and sodium in the leaching solution can be directly separated using membrane-electrolysis. Meanwhile, the Na...
Here, a novel approach has been proposed to synthesize NaP zeolite adsorbents doped with transition metals (M-NaP) using the Na2SiO3 and NaAlO2 compounds extracted from fly ash via activation and stage treatment. The preparation process of M-NaP employed the in-situ synthesis in combination with organic complexation method. The effects of the addit...
