Description of studied samples.

Sample ID	Sample composition	Sample preparation
Sample 1	2 g of CaCO3 dr. 5	Weighed and subsequently calcined
Sample 2	2 g of Sorbacal SP	Weighed and subsequently calcined
Sample 3	2 g of Sorbacal H 90	Weighed and subsequently calcined
Sample 4	2.4 g of CaCO3 dr. 5	Weighed and subsequently calcined (same as sample 1 but 20 wt. % more limestone)
Sample 5	2 g of Sorbacal SP	No calcination—weighed and inserted into the apparatus without calcination
Sample 6	2 g of Sorbacal H 90	No calcination—weighed and inserted into the apparatus without calcination
Mixture A	2 g of CaCO3 dr. 5 + 20 wt. % of Sorbacal SP	CaCO3 weighed and subsequently calcined, Sorbacal uncalcined
Mixture B	2 g of CaCO3 dr. 5 + 20 wt. % Sorbacal H 90	CaCO3 weighed and subsequently calcined, Sorbacal uncalcined
