Desulfurization

Ammonia induction strategy for preparation of transition metal oxides / zeolite H₂S adsorbent

Researchers propose an ammonia induction strategy to improve the sulfur capacity of zeolite-based adsorbents, enhancing desulfurization performance in blast furnace gas. The method inhibits agglomeration, increases dispersibility, and improves diffusion of H2S, resulting in higher adsorption rates.

The flue gas desulfurization process in powder-particle spouted beds simulated by the adjusted mesoscale drag model is more accurate

A new drag model for powder-particle spouted beds has been developed and tested, achieving higher accuracy in simulating the desulfurization process. The model's structure-activity relationship has been shown to improve predictions of particle velocity, water vaporization rates, and mass fractions.

Enhanced photocatalytic activity by Cu2O nanoparticles integrated H2Ti3O7 nanotubes

Researchers developed a new photocatalyst by integrating Cu2O nanoparticles with H2Ti3O7 nanotubes, showing improved photocatalytic activities for organic pollutant degradation. The composite exhibits stronger visible spectral response and wider absorbance, reducing bandgap energy and inhibiting electron-hole pair recombination.
