Fixation of carbon dioxide, and processing and recycling of waste of by a hydrothermal sonochemistry

1. 研制了一种小批量反应装置，该装置可将超声波输入可放置在高温高压反应场所的声化学反应容器中，对反应容器进行加热，研究了超声波在水下高温高压下是否可能入射并同样观察到畸变波形。研究了加热温度对超临界水条件（374℃，22MPa）的影响，并以此作为空腔产生的判断标准。在超临界水条件下利用超声波产生热点的可能性是可能的，并且在水热反应中通过这种方式进行声化学反应可以有效地提高反应效果。通过硫化氢从水中生成氢气的检验到平成17财政年度，将考虑通过硫化橡胶和硫化氢更多地固定CO2，并推测硫化氢从水中返回的CO2的减少固定效果。为此，研究了反应条件对硫化氢从水中产氢反应的影响及其反应机理。(1)反应条件对硫化氢制水制氢反应的影响(a)硫化氢制水制氢反应发现需要250℃以上的碱性水热反应场所。(b)虽然在60min之前氢气的出气量随着反应时间的增加迅速增加，但60min之后的增加趋于稳定。(c)氢的出现量取决于HS-的数量。(2)通过对水溶液中硫化氢反应后的产氢反应机理进行离子分析，检测出硫酸和硫代硫酸离子。认为H2S被氧化，电子被释放，电子被提供给还原。以葡萄糖为碳水化合物模型物的实验结果表明，反应后的CO2量略有下降，但葡萄糖的存在并没有造成明显的差异。少

1. The small batch type reaction apparatus which can enter an ultrasonic wave into the possibility reaction vessel of sono-chemical application which can be put on a high temperature high-pressure reaction place is manufactured, The reaction vessel was heated, it investigated whether incidence and the same observation of a distortion waveform would be possible in an ultrasonic wave to high temperature high-pressure underwater, and the existence of the influence by heating temperature was investigated to the conditions (374 degrees C, 22MPa) of the supercritical water which makes this the criterion of judgment of cavity generating. The possibility that generating of a hot spot which used the ultrasonic wave also on supercritical water conditions was possible, and sono-chemistry reaction by this was effective in promotion of the reaction effect in a hydrothermal reaction was shown.2. Examination of hydrogen generation from water by hydrogen sulfideBy the Heisei 17 fiscal year, reduction … More fixation of CO2 by vulcanization rubber and hydrogen sulfide will be considered, and it will be surmised that the reduction fixed effect of CO2 returned CO2 by hydrogen from the water by hydrogen sulfide. Therefore, it investigated about the influence and the reaction mechanism of reaction conditions which are exerted on the hydrogen generation reaction from the water by hydrogen sulfide.(1) Influence of the reaction conditions exerted on the hydrogen generation reaction from the water by hydrogen sulfide(a) The hydrogen generation reaction from the water by hydrogen sulfide found that an alkaline water heat reaction place of 250 degrees C or more was required.(b) Although the amount of emergence of hydrogen increases rapidly in time earlier than 60min with the increase in reaction time, the increase after 60min is stabilizing.(c) Depend for the amount of emergence of hydrogen on the quantity of HS-.(2) As a result of conducting ion analysis about the solution after the hydrogen generation reaction mechanism reaction from the water by hydrogen sulfide, sulfurous acid and thiosulfuric acid ion were detected. It is thought that H2S oxidized, electrons were emitted and the electron was supplied from this result for reduction.3. Examination of CO2 reduction at the time of using carbohydrate as reducing agent As a result of experimenting using glucose as a model thing of carbohydrate, after-reaction CO2 quantity was decreasing a little, but the significant difference by the existence of glucose was not seen.
