In the current research, isothermal experiments of kinetic analysis were performed at different temperatures (800–1050 °C) and particle sizes (885 to 10,763 μm) to investigate the calcination kinetics of high-purity limestone. Thermal analyses were carried out in a zirconia crucible, 1 cm in height, for different temperatures and particle sizes. …

1. Introduction. The ocean plays a major role in controlling atmospheric carbon dioxide and storage of anthropogenic carbon (Gruber et al., 2019).For the last decade, ocean uptake of anthropogenic carbon was 2.5 ± 0.6 Pg C year −1, that is, about 23% of annual anthropogenic carbon emissions due to fossil fuels, cement production, and land‐use …
