目前,关于超临界水的大量研究成果层出不穷,人类在这项技术的发展上也取得了可喜的成果。整个过程只需要30分钟,这是酸催化剂处理时间的二十分之一,回收效率可高达80%。

安德里亚指出,超临界水的研究非常有意义。

据报道, 这个热液喷口位于大西洋中脊,它是由Andrea Koschinsky教授于2005年首次发现的, 不来梅雅各布斯大学的地球化学家, 德国, 和她的研究团队。出水口附近的最高水温达到464°C,这不仅是自然界中温度最高的液体,这也是首次以自然状态观察到超临界状态的水。该方法还可以将电线的塑料护套制成煤油和煤油。据报道, 日本化学技术战略局正计划将超临界水用于发电技术。当超临界水达到500℃时,他们增加氧气,然后加工PVC塑料,99%的处理过的塑料会分解,和, 氯化物的产量很小, 避免过去因燃烧塑料而产生的有毒氯化物造成的环境污染。更令人惊讶的是,水实际上处于超临界状态。他们之中, 德国和日本是最突出的。它的成熟应用必将给人类解决许多问题带来惊喜。这是迄今为止科学家在地球上发现的最热的水。安德里亚(Andrea)说,一般来说, 在开始工作之前,钻头已被高温融化。在2005年,当他们测量热液射流周围的液体温度时,我发现即使最低温度是407°C,最高温度达到惊人的464°C。right now, Many countries in the world are conducting research, Development and utilization of supercritical water.Another feature is that it can be mixed with oil and other substances,Has a wide range of integration capabilities.Andrea pointed out,Supercritical water has two notable characteristics.

Netease discovered news on August 5 According to a report on the "New Scientist" website,recent,German scientists discovered this when studying high-temperature hydrothermal vents at the bottom of the Atlantic Ocean.If Japanese researchers develop a technology,Use supercritical water to recover and dispose of harmful toluene diamine.Andrea is very excited about this discovery,she says,"It is indeed water,But not ordinary water.In the past, People can only reach the supercritical state of water through laboratory technology.Or oxidized by water in supercritical state

Spectacular views of hydrothermal vents

.Some can also ignite spontaneously,The flame rushed into the water.This is the first time that humans have observed the existence of supercritical water in the natural state.at this time,There is no difference between liquid and gas in water,Completely fused together to become a new type of high temperature and high pressure liquid.The earth's crust expands and separates,Sea water seeps into the ground and forms hydrothermal fluid when exposed to hot magma,The hydrothermal fluid transports the minerals from the discharge port back to the sea.with,The recycled products can be reused,As a raw material for the manufacture of polyurethane resins."

Japan has incorporated the research and development of supercritical water into its high-tech research plan. Andrea said,The underwater hydrothermal vent is also called "underwater black chimney",It is formed by the expansion and separation of submarine shells.One is that it has a strong oxidizing ability,将要处理的材料放入超临界水中,充满氧气和过氧化氢,该物质将被氧化和水解。因为他们不能直接使用机械来获取热液喷口的样本。排出高温液体后, 遇到冷海水,冷凝并固化溶解在热液体中的硫化物。德国开发了一项技术,超临界水可用于处理污染物。

据了解,所谓的超临界水,这意味着当压力和温度达到一定值时,由于高温而膨胀的水的密度与由于高压而压缩的水蒸气的密度完全相同。这些特性使超临界水产生奇怪的功能。此外,他们还使用超临界水,在400°C和300个大气压下,氧化燃烧的灰烬中的有毒物质,几乎完全分解以达到无害化。他们在接下来的几年中对热液喷口进行了长期的跟踪研究

但,科学家只能使用计算机模型来研究这种超临界水的形成。凝固的矿物质继续积聚在热液出口附近,最终形成了巨大的“烟囱”。恢复率也可以达到80%,而且所用的时间比热分解方法要短得多。投入了大量的金钱和人力
