Although many CO 2 determinations have been made on deep-sea sediments there is in the literature very little information about the relative abundance of CaCO 3 and MgCO 3. In this investigation the contents of CaO and MgO in two per cent acetic acid extracts were determined by gravimetric ...
The behaviors of lithium carbonate, calcium carbonate and magnesium carbonate contained in the mixture salts from Zabuye Saline in Tibet during carbonation process was discussed. 对西藏扎布耶混盐中的碳酸锂及其所含的钙镁碳酸盐在碳酸化过程中的行为进行了探讨,考察了碳化过程中碳化时间、碳化温度对碳酸锂溶...

The effects of Mg on carbonate precipitation and solubility were assessed in isolation from other carbonate precipitation inhibitors commonly found in soils. Five bentonite systems were preconditioned by saturation with different proportions of exchangeable Ca and Mg. Calcium/magnesium ratios ranged from 99...
A gas, formed as a product of a pyrolysis of oil shale, is passed through hot, retorted shale (containing at least partially decomposed calcium or magnesium carbonate) to essentially eliminate sulfur contaminants in the gas. Specifically, a single chambered pyrolysis vessel, having a pyrolysis ...
