对一系列具有不同化学计量的白云石和方解石的样品使用碳酸化/煅烧循环，研究了烧结对 CO2 最大捕获效率的影响。对于属于石灰石和白云质石灰石类别的材料，烧结在所研究的两个不同的最高温度下显着降低了碳化程度。相同最高加热温度下的碳化程度主要取决于白云石的百分比。白云岩中的烧结可以忽略不计，特别是在最高加热温度 1005 摄氏度时。载气的成分似乎没有发挥重要作用。石灰石中第二次加热/冷却循环时碳化程度的降低，以及白云岩中足够连续的煅烧/碳化循环后的耐久性，似乎不受实验中使用的最高煅烧温度的影响。
The effect of sintering on the maximum capture efficiency Of CO2 is studied, using a carbonation/calcination cycle for a series of samples with different stoichiometries of dolomite and calcite. For the materials that belong to the categories of limestone and dolomitic limestone, sintering decreases the extent of carbonation significantly at the two different highest temperatures studied. The extent of carbonation for the same maximum heating temperature depends mainly on the percentage of dolomite. Sintering is negligible in the dolomitic rocks, especially at the maximum heating temperature of 1005 degrees C. The composition of the carrier gas does not seem to play a significant role. The reduction of the extent of carbonation at the second heating /cooling cycle in limestone, and the durability after enough successive cycles of calcination/carbonation in the dolomitic rocks, does not seem to be affected by the maximum temperatures of calcination that were used at the experiments.
