-The sulphidation of calcined limestone with H2S , COS and mixtures of H2S and COS was studied in a thermogravimetric analyzer at temperatures between 500 and 700°C. The applied H2Sand COS-pressures corresponded with those in coal gas produced by modern coal gasifiers, i.e. 50-12,000 Pa for H2S and 50-1000 Pa for COS. The reaction orders in H2S and COS as well as the activation energies of the ...

Abstract Fuel cells powered by biogas for decentralised cogeneration of heat and power are an attractive alternative to combustion technologies. However, contains sulfur-based compounds (H 2 S, COS, DMS, siloxanes), which harmful fuel cells. This work was carried out in the framework European project Waste2Watts, involving laboratories Politecnico di Torino, ENEA, PSI. The aim is design test a ...
