Abstract

This article deals with the cleaning of generated gas for energy use in high-temperature fuel cells by the method of hightemperature adsorption in the potential utilization according to Industry 4.0. The study presents the methods of preparation of a wide range of sorbents, test equipment, used analytical methods and overview of achieved results. This project focused on high-temperature removal of acidic components such as hydrogen sulfide, Carbonyl sulfide, hydrogen chloride and hydrogen floride (H₂S, COS, HCl and HF), using laboratory-made or commercial sorbents, from the gas resulting from the gasification of biomass. In the theoretical part of the biomass and its gasification, cleaning possibilities of the raw gas and, above all, of selecting a suitable adsorbent for high-temperature removal of unwanted components was the major focus. The possibilities of using purified gas in fuel were also mentioned in the article and the properties and structure of the fuel cell. The experimental part of the project addressed the testing of specific adsorbents at different temperatures. The task was to find a sorbent that would clean the raw gas at the specified temperature to the desired concentrations of undesirable components in order to enter as fuel into a high-temperature fuel cell. Commercial and naturally obtained dolomite were modified and tested. The effective time range of sorbents at atmospheric pressure (101.325 kPa) and at different temperatures ranging from 300 to 600 °C were also measured. From the results obtained, modified dolomite was established to be more effective adsorbent for the removal of hydrogen sulphide gas from syngas produced from biomass.
