••
TL;DR: In this article, the sulphur capacity of 14 European limestones was studied under constant oxidizing as well as under alternating oxidizing and reducing conditions, and the relative ranking of the limestones appears to be little influenced by the reaction conditions.
83 citations
••
TL;DR: In this paper, three different types of limestones were compared with respect to their capacity for reaction with sulphur dioxide, and a negative correlation exists between the time required for calcination and the sulfur dioxide capacity.
83 citations
••
TL;DR: A modified grain model of the reaction between calcined chalk, sulphur dioxide and oxygen has been developed, and the model has been verified by comparison with a large volume of experimental data as mentioned in this paper.

TL;DR: In this paper, the authors presented four convenient methods for determination of the mean residence time and axial dispersion coefficient of a flow system by analysis of data obtained by means of the imperfect tracer pulse method.

••
TL;DR: The reversible reaction between CaO and CO2 is an extremely promising method of removing CO2 from the exhaust of a power station, generating a pure stream of CO2 ready for geological sequestration.
880 citations
••
TL;DR: In this paper, a review of the literature on using lime from limestone to sequester CO 2 from combustion systems is presented, and the physical properties of calcined products after sintering and reaction are reviewed.
494 citations
••
TL;DR: In particular, the mechanisms of the sulfation reaction are still not properly understood, and there is dispute over the explanation of the well-known temperature maximum for optimum sulfur capture found in FBC boilers as mentioned in this paper.
414 citations
••
TL;DR: In this paper, the authors focus on processes in large circulating fluidized bed combustors, and especially on mixing between fuel and air, which is important for combustion but also for sulphur capture through the formation of reducing zones.
195 citations
••
TL;DR: In this article, the authors focus on sulfur removal technologies in industrial grate furnaces (IGF) and pulverized coal fired boilers (PCFB) with high flame temperature of 1200-1600 °C.
