At the forefront is the development of cobalt-doped mesoporous molecular sieves grafted with N,N-dihydroxypyromellitimide (Co-SBA-15-NDHPI), which demonstrates record stability during catalytic oxidative desulfurization. This organic-inorganic composite strengthens the synergistic effect between active components and porous supports, significantly improving sulfide-to-sulfone conversion efficiency while resisting deactivation.

Integrated Dehydration-Desulfurization Units Gain TractionModern dehydration unit designs incorporate these advances with optimized operational frameworks:

Modular configurations: Skid-mounted units with automated switching between adsorption, regeneration, and cooling cycles (dual or triple-tower systems) enable continuous -70 degrees C water dewpoint operation critical for LNG/NGL processes

Regeneration efficiency: Direct-fired or electric heaters now regenerate molecular sieves at 230-300 degrees C using dry gas counterflow, restoring adsorption capacity while reducing energy consumption by up to 30%

Multi-pollutant control: Next-gen molecular sieves simultaneously target HS, SO, and water vapor through tailored pore structures-microporous (
