Hydrogen Sulfide Capture Using Amine-Modified Mesoporous Oxides
The primary objective is to investigate the effects of amine type, support type and humidity on the adsorption of H2S. I aim to explore the selectivity (vs. methane) and stability of amine-modified mesoporous oxides and identify and quantify the species that are formed from H2S-amine interactions. The rationale of this research is that by developing amine-H2S-oxide structure-property relationships for these materials, the requisite fundamental understanding of the adsorption process will be obtained such that the rational design of improved adsorption materials, tailored for H2S interactions, will be possible.
