碳酸化

Using wollastonite to fix the carbon-dioxide via carbonation reaction seems to be one of the effective methods.

利用钙矽石与二氧化碳做反应，经由碳酸化反应将其固定成为碳酸钙，是为有效的方法之一。

However, it is difficult to manufacture the large size carbonization tower because of its special structure.

但由于其中的主要设备碳酸化塔结构大型化困难，多年来只在小型厂中采用，发展不快。

Minimum oxygen content and CO2 consumption, the deaerted water is also carbonated when processing deaeration.

该装置具有低氧含量和最低的CO2置换气体消耗量，出水在二氧化碳置换后，在脱氧的同时也达到了一定的碳酸化。

The tower high about 6 meters, put the brewing water to the deaeration tower to oxygenate directly, adopt CO2 permutation, while completed the deaeration, the deaeration water also to achieve the partial carbonation goal.

塔高约6米，直接将酿造水进入脱氧塔进行脱氧，采用CO2置换，在完成脱氧的同时脱氧水也达到了部分碳酸化目的。

The study on the hardening mechanism of the soft soil with the materials shows that the hardening procedure can be divided into three stages:(1). Hydrating and dissolving stage, when material A and material B of the high-water-content and quick-setting materials respectively dissolve and balance in water.(2). Gel and consolidating stage, when the materials hydrate into calcium crystal and the ion exchange and aggregation of soil particles occur in an alkaline environment.(3). the structure developing stage, when the calcium crystals connect each other, absorb and crystallize the water around; the hydrate remnants, calcium hydroxide, carbonate continuously in water and in the air.

本文对高水速凝材料-软土硬化机理的研究表明，高水速凝材料-软土的硬化过程可分为三个阶段：①水化溶解阶段：主要为高水速凝材料的甲、乙料分别与水的溶解、维持平衡阶段；②胶凝固化阶段：主要为高水速凝材料的水化反应生成钙矾石晶体以及土颗粒在碱性环境中发生离子交换和团粒化作用；③强度增长阶段：钙矾石晶体相互连接，大量吸收周围环境中的水分，并将水分变成自己的结晶水；水化残余物氢氧化钙在水中和空气中发生碳酸化作用。

Therefore we believe this phase diagram can apply to phase diagram analysis of trona carbonation and phase diagram calculation.

最终认为该相图同样可用于天然碱碳酸化相图分析与相图计算。

RESULTS AND CONCLUSION: PCHC: Intra-bone mechanical strength was lower at 2 weeks, the lowest at 4 weeks, but then closed to intension of normal cancellated bone at 8 weeks, higher than normal cancellated bone at 12 weeks, and recovered to the level of normal cancellated bone at 16 weeks.

结果与结论：多孔碳酸化羟基磷灰石骨水泥：2周时的骨内力学强度较低，4周时降到最低，8周时接近正常松质骨强度，12周时超过正常松质骨强度，16周时恢复到正常松质骨水平。

This may be done by periodically pumping the beer through a carbonator or bubbling carbon dioxide into the storage tank.

这可以通过定期输送啤酒流经碳酸化器或者通过向储罐内充入二氧化碳来完成。

It is convenient for sinter to be leached, and the secondary reaction appears little. The slurry after sinter leaching is transferred into autoclave for desilicification at about 170℃, and the siliceous modulus of solution reaches more than 200. Then some lime is added for deep-desilication at normal pressure, the siliceous modulus of solution increases more than 600 even if the Al2O3 content is more than 200g/L.The SiO2 coefficient in hydrate garnet from deep-desilication is more than 0.28. Under conditions of the addition of seed and application of novel technology of carbonization, the contents of Na2O and SiO2 in product are less than 0.37% and 0.025%, respectively.

实验结果显示：烧成的熟料溶出条件宽松，二次反应程度弱；溶出浆液在170℃左右直接进行加压脱硅，脱硅后溶液的硅量指数大于200，再加入适量的石灰进行深度脱硅，即使溶液中氧化铝浓度超过200g/L时，精液的硅量指数也大于600，且得到的水化石榴石中二氧化硅饱和系数大于0.28；通过加入晶种和采用新的碳酸化分解工艺制度，产品中的SiO2 含量降至0.025%， Na2O含量小于0.37%；加入表面活性剂，不仅能将碳分母液蒸发至Na2OT浓度大于300g/L，而且还可有效减缓表面上结疤的形成速度。
