Removal of Hydrogen Sulfide (H2S) from Biogas Using Zero-Valent Iron

Abstract

University of Michigan, where he studied the solidification and oxidization in reactor using the experimental method and numerical simulation. In 1993, he became the associate professor at Kagoshima University, where he studied the thermal fluid flow transport phenomena for rotating machinery and combustion and the development of turbulence model. Since 2003, he became a professor of Department of Mechanical Engineering at Kumamoto University. His research interest on production and development of clean energy and renewable energy, thermal fluid flow transport phenomena using nanofluids, advanced cooling device development with the use of nanofluids and development of new clean fuel with the aid of shock-wave.

Removal of Hydrogen Sulfide from Biogas Using a Red Rock

“…The pore size evaluation of all samples shows they are of more mesopores rather than macrospores. Availability of micropores and mesopores should favor adsorption as reported in the literature [21]. (Figure 3(c)) showed there was small but irregular pore size with roughness on surface due to calcination effect as the result surface area increased which reflects Table 2 above.…”

Desulphurisation of Biogas: A Systematic Qualitative and Economic-Based Quantitative Review of Alternative Strategies

“…In general terms, adsorption may be classified as either physisorption or chemisorption processes, with their major differences summarised in Table 1. In the context of the present review interest, the adsorbate is H 2 S gas, while the adsorbent may be a solid such as activated carbon, impregnated activated carbon, zeolites, or an iron oxide-based material [64]. Activated carbon is commonly employed as the preferred adsorbent because it is a highly porous material with a high adsorption capacity and is reported as being efficient in the removal of low concentrations of H 2 S from biogas via the physisorption process [65].…”

Hydrogen sulfide removal from biogas using a salak fruit seeds packed bed reactor with sulfur oxidizing bacteria as biofilm

“…Thus, the mathematical models representing the H 2 S removal from biogas using biofilm on packed bed of SFS are the set of Eqs. (2),(7), (10), (12) and (16). The proposed models have been tested for the experimental data obtained by Fischer [18] and give reasonably results [24].…”

“…Several physicochemical processes have been used to remove H 2 S from industrial waste gas streams which include absorption [9,10], scrubbing [11], and adsorption [12] processes. Meanwhile, biofiltration is an alternative process for H 2 S removal from gas [7,13].…”
