创建正确的(绿色)化学二氧化碳、水和生物材料
文摘
绿色科学(然后提到现在可支持的科学)是科学管理的一部分的结构和发展过程和项目以低,或疏散,有害物质的创造和运用。绿色科学并不等同于生态科学。前面的聚光灯对自然科学和经济实践的改进效果,友好,(例如,减少不可持续的资产的利用率和程序控制生态污染)。最后一个聚光灯的影响具体合成混合物对地球有害的或不安全的。众多混合物混合反应,完成机械规模需要大量的复合溶剂。此外,这些溶剂同样利用现代脱脂和清洗的目的。尽管如此,许多传统溶剂被用于这种目的在过去被认为是有害的。无论同样已知氯化溶剂。许多现代程序通常使天然气的副作用,不能使用。尽管天然气老化过程,微生物的混合气体转化为激发——确实存在,大多数气体副作用没有正确的混合气体成熟所需的原子。 Dihydrogen, which is regularly essential, is especially rare in modern gas results. To address this hole, Illinois-based LanzaTech Inc. created exclusive organisms that can change over the gas side-effects into energizes without dihydrogen. This advancement procedure makes it conceivable to use gas maturation in more settings and more enterprises, and the monetary advantages of having the option to deliver energizes out of existing gas results are clear. In addition, outsider LCA examination demonstrated that powers made through LanzaTech's procedure makes 70% less ozone depleting substances than customary petroleum derivatives, notwithstanding a decrease in particulate issue and other sub-atomic side-effects that add to smog.In the billion years history of our earth, a generally astonishing and exceptional procedure has happened of the gigantic transformation of the plentitude of the current CO2 in the air with water into biomass or biomaterials affected by sunlight based vitality, a procedure we call: photosynthesis. On account of this procedure the CO2 in the world's environment dropped from 20% to ±250 to 300 ppm. Some portion of these biomaterials more than billions of years has been debased (or "fossilized") and changed over into coal, oil and gas, or what we call today non-renewable energy sources. The quickened utilization of these fossil assets throughout the most recent 200 years has prompted a sharp increment in CO2 , now as of now at 400 ppm and furthermore the expansion of methane (CH4 ) in the climate, activating a worldwide temperature alteration. It is our duty to design, create and apply the correct green science utilizing the accessible characteristic assets, for example, CO2 , water and biomaterials in a way which doesn't hurt the environments of our earth, which means in a roundabout and reasonable way. Models will be given of developments in this energizing field in the course of the most recent 15 years, prompting new innovations, opening the opportunities for: Advanced materials and synthetics from biomass and biomass squander; Fuels and synthetic concoctions from CO2 and water from the outside, utilizing clean sustainable power source (sunlight based, wind, hydropower and so on.).
