Activated Carbons for Syngas Desulfurization: Evaluating Approaches for Enhancing Low-Temperature H2S Oxidation Rate
Autor: Christian Frilund, Ilkka Hiltunen, Pekka Simell
Publikováno v: ChemEngineering, Vol 5, Iss 2, p 23 (2021)
Its relatively low cost and high surface area makes activated carbon an ideal adsorbent candidate for H2S removal. However, physical adsorption of H2S is not very effective; therefore, methods to facilitate reactive H2S oxidation on carbons are of in

Development of a simplified gas ultracleaning process
Autor: Christian Frilund, Ilkka Hiltunen, Esa Kurkela
Publikováno v: Frilund, C, Kurkela, E & Hiltunen, I 2021, ' Development of a simplified gas ultracleaning process : experiments in biomass residue-based fixed-bed gasification syngas ', Biomass Conversion and Biorefinery . https://doi.org/10.1007/s13399-021-01680-x
For the realization of small-scale biomass-to-liquid (BTL) processes, low-cost syngas cleaning remains a major obstacle, and for this reason a simplified gas ultracleaning process is being developed. In this study, a low- to medium-temperature final
