项目摘要

A new way to control properties of liquid CO2 will be found. This will allow the liquid properties of CO2 to be remote-controlled, using light as a switch. Today, reduction in atmospheric CO2 levels is the greatest challenge facing scientists, engineers, politicians and economists.1 Of all the solutions proposed CO2 capture, sequestration and storage is recognized as a viable approach to control CO2 levels. However, CO2 entrapment and storage technologies will require efficient and effective command over the fluid properties of CO2; obviously, vast volumes of liquid CO2 will need to be handled and processed. For example, CO2 sequestration in sandstone or limestone reservoirs that occurs during CO2 enhanced oil recovery (EOR) would be more economically viable and technically efficient if viscous fingering could be suppressed by thickening the CO2. Although on paper the concept appears to be straightforward, that is find scCO2-compatible additives, as is commonly done for water (soaps and detergents, synthetic and bio-polymers, salts and co-solvents), in practice there are significant physico-chemical barriers to overcome. What it all comes down to is the inescapable fact that feeble intermolecular interactions make CO2 a very weak solvent, being essentially in a class of its own when compared to water and any other polar or apolar organic solvents. The upshot is that most commercially available solutes are incompatible with scCO2, and so the scope for solvent modification using readily available additives is at best extremely limited. Simply put, CO2 is one of the most stubborn of all chemical beasts, and taming it presents a great chemical engineering challenge. This project will design and generate new additives (surfactants) which and be using external light: this will allow us to control the CO2 fluid properties at the flick of a switch , as this cannot be done using any of the currently available chemicals. . This would open the doors to optimization of CO2 for industrial chemistry processes, as an environmentally friendly solvent, and also for processing and handling fluid CO2 in carbon capture technologies, for effective subterranean storage.

一种控制液态CO2性质的新方法将被发现。这将允许利用光作为开关来远程控制CO2的液态性质。今天，降低大气中的二氧化碳水平是科学家、工程师、政治家和经济学家面临的最大挑战。1在所有提出的解决方案中，二氧化碳捕获、封存和储存被认为是控制二氧化碳水平的可行方法。然而，CO2捕集和储存技术将需要对CO2的流体性质进行高效和有效的控制;显然，将需要处理和加工大量的液态CO2。例如，如果可以通过增稠CO2来抑制粘性指进，则在CO2强化采油（EOR）期间发生的砂岩或石灰岩储层中的CO2封存将在经济上更可行并且在技术上更有效。虽然在纸面上，这个概念似乎很简单，即找到scCO 2兼容的添加剂，就像通常对水所做的那样（肥皂和洗涤剂，合成和生物聚合物，盐和共溶剂），但在实践中，有重要的物理化学障碍需要克服。这一切归结为一个不可避免的事实，即微弱的分子间相互作用使CO2成为一种非常弱的溶剂，与水和任何其他极性或非极性有机溶剂相比，它基本上属于自己的一类。结果是大多数市售溶质与scCO 2不相容，因此使用容易获得的添加剂进行溶剂改性的范围充其量是极其有限的。简单地说，二氧化碳是所有化学野兽中最顽固的一种，驯服它是一个巨大的化学工程挑战。该项目将设计和产生新的添加剂（表面活性剂），并使用外部光：这将使我们能够控制CO2流体的特性，因为这无法使用任何现有的化学品。.这将打开大门，优化CO2的工业化学过程，作为一种环境友好的溶剂，也为处理和处理流体CO2的碳捕获技术，有效的地下储存。
