海水做燃料 機會又進一步 美海軍研究中

(NaturalNews) U.S. Navy scientists are investigating a method for transforming ocean water into jet fuel as a way to maintain U.S. military superiority even in the face of dwindling global oil supplies.
NaturalNews)美國海軍科學家正在研究一種方法,將海水轉化成飛機燃料,以此來保持美國的軍事優勢,甚至在面世臨全球石油供應減少時候。“
"The U.S. Navy is surrounded by seawater and the Navy needs jet fuel," said researcher Robert Dorner, who works at the Naval Research Laboratory in Washington, D.C. "In the seawater you have [carbon dioxide] and you have hydrogen. The question is, how do you convert that into jet fuel?"
美國海軍周圍被海水環繞和海軍正需要飛機燃料,”研究員Dorner說,他在華盛頓特首都的海軍研究實驗室工作。“在海水中你有[二氧化碳],和你還有氫;問題是,你如何將其轉化為飛機燃料?”
The navy researchers hope to develop a new version of the Fischer-Tropsch process for combining carbon monoxide with hydrogen to produce synthetic gas (syngas), a precursor for both jet fuel and plastics. The Fischer-Tropsch process requires the use of cobalt catalysts and heat, and also produces waxes and the greenhouse gas methane as byproducts. Because of its high cost, it has rarely been used commercially -- most notably, the isolated regimes of Nazi Germany and Apartheid South Africa used it to transform solid coal into liquid fuel as a way of working around fuel embargoes.

Dorner and colleagues hope to modify the process to use the carbon dioxide dissolved in sea water instead of carbon monoxide, and an iron catalyst rather than cobalt. This latter change would reduce methane output by 70 percent and also increase syngas output. If this is successful, the researchers would then need to find a way to turn syngas into jet fuel.
Dorner和他的同事希望修改過程,使用二氧化碳代替一氧化碳在海水中溶解,和鐵催化劑而不是鈷;後者的改變將會令甲烷產量減少百分之七十,亦增加合成氣產量。如果這成功,研究人員跟住便需找到一種方法去把合成氣轉為飛機燃料。
"It's still a very energy-intensive process," Dorner said. "A lot of work remains to be done. We haven't even really looked at building an actual pilot plant yet."
這仍然是一個非常能量密集的過程,“Dorner說。”還有很多工作要做,我們甚至還未曾真正睇睇建立一間實際的試點工廠。“
According to Jean-Michel Lavoie of Sherbrooke University in Quebec, oil prices remain low enough that even a modified Fischer-Tropsch process is unlikely to become economical soon. The idea remains appealing to the navy, however.

Dorner says that if the Navy decides to adopt the technique, it would probably install the production factory in a separate ship, which jets would then visit in order to refuel.
