AbstractMineral trapping through the precipitation of carbonate minerals is a potential approach to reduce CO2 accumulation in the atmosphere. The temperature dependence of amorphous magnesium carbonate (AMC), a precursor of crystalline magnesium carbonate hydrates, was investigated using synchrotron X-ray scattering experiments with atomic pair distribution function (PDF) and X-ray absorption fine structure analysis. PDF analysis revealed that there were no substantial structural differences among the AMC samples synthesized at 20, 60, and 80 °C. In addition, the medium-range order of all three AMC samples was very similar to that of hydromagnesite. Stirring in aqueous solution at room temperature caused the AMC sample to hydrate immediately and form a three-dimensional hydrogen-bonding network. Consequently, it crystallized with the long-range structural order of nesquehonite. The Mg K-edge X-ray absorption near-edge structure spectrum of AMC prepared at 20 °C was very similar to that of nesquehonite, implying that the electronic structure and coordination geometry of Mg atoms in AMC synthesized at 20 °C are highly similar to those in nesquehonite. Therefore, the short-range order (coordination environment) around the Mg atoms was slightly modified with temperature, but the medium-range order of AMC remained unchanged between 20 and 80 °C.

Małopolska Block

The experimental research in brine–rock–gas was performed in order to investigate the interactions of hydrogen sulphide with selected aquifer rocks from the Małopolska Block (Poland). Scanning microscopic analysis of reacted samples confirmed intense dissolution of the cement components (mainly hematite and carbonates). It was also found that the main process leading to hydrogen sulphide mineral trapping is its reaction with hematite, leading to the formation of iron (III) sulphide. Based on modeling of kinetic reactions we also assessed the amounts of sulphur blocked in the mineral form and in solution. On this basis, it was hypothesized that the analyzed rocks have significant potential for geological sequestration of H2S in the long term.
