Influence of Surface Characteristics of Palm Shell Activated Carbon Modified with Nanostructured Nickel for Reactive Adsorption of Hydrogen Sulfide

Hydrogen sulfide (H2S) is a colorless and toxic gas that could harm people and the environment. Due to its acidic and toxic properties, H2S cannot be burnt directly, hence it is necessary to remove it. The aim of this work is to study the influence of surface characteristics of modified palm shell a...

The performance of modified Ni nps with PSAC (Ni-PSAC) adsorbents was tested in a custom-design H2S scrubber for H2S removal application.
