摘要
The chemical behaviour of calcium hydroxide, used as sorbent in the dry desulphurization process at low temperatures has been evaluated by means of thermochemical analysis. The final solid of the desurphurization reaction at low temperatures under conditions simulating exhausting flue gas from coal fired plants has been identified as a mixture of calcium sulphite monohydrate, calcium carbonate and unreacted calcium hydroxide. The influence of the flue-gas composition and the solid conversion in the chemical composition of the final solid has been studied. Results allow the main characteristics of the dry desulphurization reaction at low temperatures using calcium based sorbents to be established by means of thermochemical analysis.
