Activity, selectivity, and stability of vanadium catalysts in formaldehyde production from emissionsof volatile organic compounds
In this study, activity, selectivity and stability of vanadium catalysts supported on zirconia, hafnia, and alumina were examined in the oxidation of methanethiol and methanol to formaldehyde. The 3 wt-% vanadia–alumina catalyst with low VOx surface density showed the highest activity in the formaldehyde production. However, during the stability test, this catalyst deactivated due to the change in the oxidation state of vanadium from V5+ to V4+, decrease the amount of surface vanadium species and the formation of sulphates on the material surface. Zirconia and hafnia supported catalysts with high VOx surface density ...

In situ monitoring of pore structure of magnesium oxysulfate cement paste: Effect of MgSO4/H2O ratio
Publication date: 25 March 2020Source: Journal of Industrial and Engineering Chemistry, Volume 83Author(s): Shengwen Tang, Changrong Wei, Rongjin Cai, Jiasheng Huang, E. Chen, Junhui YuanAbstractThis work systematically presented the pore structure evolution of different magnesium oxysulfate (MOS) cement pastes by non-contact impedance measurement (NCIM), fractal theory and other microstructural experiments. According to the evolution of electrical impedance response, three hydration stages (dissolution, acceleration and hardened stages) can be identified in the pastes. Furthermore, based on the results obtained from NCIM ...

Improved antifouling and self-cleaning ability of PVDF ultrafiltration membrane grafted with polymer brushes for oily water treatment
This study focuses on the modification of commercial polyvinylidene fluoride (PVDF) membranes using surface-initiated atom transfer radical polymerization (SI-ATRP) method. Poly(N-isopropylacrylamide) (PNIPAAm) was grafted from PVDF surface and then PEGMA was grafted onto the PVDF-g-PNIPAAm membrane. The aim of the research was to prepare membranes that simultaneously have antifouling and self-cleaning properties. PNIPAAm (lower block) was grafted to give the membrane temperature sensitive property and PPEGMA (upper block) was used to improve hydrophilicity. Morphology, topography and chemical composition of the modified m...

Cationic surfactant modified cellulose nanocrystals for corrosion protective nanocomposite surface coatings
Publication date: 25 March 2020Source: Journal of Industrial and Engineering Chemistry, Volume 83Author(s): Malin Ly, Tizazu H. MekonnenAbstractCellulose nanocrystals (CNCs), a robust renewable and green nanomaterial, has potential as an excellent reinforcing and multifunctional filler for polymers used in coating and other applications. However, the high polarity of CNCs limits its interfacial interaction and dispersibility with several non-polar polymers. These limitations severely constrain it from transferring its functional attributes to polymeric materials. In this paper, three differentiated cationic surfactants: ce...

Treatment of monazite processed effluent to recover rare earth metals (REMs)
Publication date: 25 March 2020Source: Journal of Industrial and Engineering Chemistry, Volume 83Author(s): Archana Kumari, Sunidhi Singh, Kavita Parmar, Devendra Deo Pathak, Manis Kumar JhaAbstractImproper disposal of effluent generated in rare earth mining areas and ore processing industries results in loss of REMs and miserably affects the ecosystem. Thus, their appropriate treatment is required, which can be achieved via environmentally feasible processes. In this connection, systematic scientific adsorption studies were carried out to separate REMs using cationic resin, Amberlite IR120 Na from the effluent generated d...

Preparation of synthetic graphite from waste PET plastic
In this study, we present a novel route for the upcycling of waste plastics, wherein synthetic graphite is prepared from a waste polyethylene-terephthalate (PET) bottle through a facile and scalable method. PET was successfully converted to graphite via a synthetic method of pyrolysis at 900 °C followed by boron-assisted catalytic graphitization at 2400 °C. This technique overcame the intrinsic non-graphitizable property of PET and yielded graphite showing high crystallinity with the maximum crystallite size of 20.9 nm in Lc and the d(002) spacing of 3.373 Å. In particular, it show...
