A high-performance adsorbent for hydrogen sulfide removal

Spatially well-distributed copper-zinc oxides supported on mesoporous silica (SBA-15 and commercial silica gel) showed high adsorption capacity for hydrogen sulfide (as high as 80 mgS/gsorbent) and stability during cyclic adsorption-regeneration process. 2014 Elsevier Inc. All rights reserved.

Growth of zeolite crystals with graphene oxide nanosheets.

Growth of silicalite with graphene oxide (GO) nanosheets occurred via attachment of GO onto the silicalite surface, and entrapment of GO nanosheets inside single crystals. Electrically conductive composites were produced by calcination in nitrogen whereas silicalite crystals with slit-like mesopores of sizes 20-25 Å were obtained after GO burn-off.

Probing Structure-Property Relationship of Active Metal Nanoparticles on Mesoporous Silica Sorbent

Zinc-based adsorbents currently in use for H2S removal from tail gas in the oil and gas industry have limited regenerability and reduced performance over multiple cycles [1,2]. Spatially well-distributed metal nanoparticles in mesoporous substrates can be effective in achieving better performance over multiple adsorption and regeneration cycles [3,4]. One of the critical aspects of understandin...
