Evaluation of natural limestones quarried in the Czech Republic in terms of their use in carbonate looping

Popis výsledku v původním jazyce

For effective operation of high-temperature sorption of carbon dioxide from the flue gas in industrial scale, it is necessary to ensure an adequate supply of affordable sorbent having suitable technical parameters. For a given technology, natural limestones meet the condition of low cost. Due to current needs to solve the issue of carbon dioxide capture in power as well as other branches of industry, this study is focused on evaluating different types of natural limestones. A set of laboratory methods for evaluation of the physicochemical properties of limestones was proposed. A laboratory apparatus, based on the principle of fixed bed tubular reactor made of quartz glass, represented the main method for measurement sorption capacities. Within the sample base, a wide spread of sorption capacities was determined in the range of 18.0 - 84.6 % of the theoretical values, based on chemical composition. After six cycles the sorption capacity decreased to 3.5 - 35.6 %, compared to the theoretical value, mainly due to sintering. It was verified that appropriate selection of limestone can significantly reduce degradation of the capacity during cyclic use.
