How China could use bio-waste to mass-produce cheap super-fuel for missiles
- Scientists’ large-scale conversion of agricultural waste into fuel offers savings up to 60 per cent, they say
- Discovery could slash military costs and bring civilian applications of hypersonic flight technology closer
Chinese scientists say they have developed a technology to convert bio-waste into fuel for missiles and hypersonic planes, reducing fuel costs by as much as 60 per cent.
The existing JP-10 super-fuel for military aircraft has numerous advantages including high energy density, good thermal stability and low freezing point, but it costs more than US$7,000 per tonne – nearly 10 times as much as ordinary jet fuel for commercial aircraft.
It is used mainly in cruise missiles and ramjet or scramjet engines on new-generation aircraft travelling at hypersonic speed, or five times faster than sound.
Scientists from the Dalian Institute of Chemical Physics, at the Chinese Academy of Sciences in the northeastern province of Liaoning, predicted using the new technology in the near future could reduce the cost to as low as US$2,547 per tonne.
The secret, according to their paper, published in the latest issue of German chemistry journal Angewandte Chemie, lies in cheap bio-waste.
Using agricultural and forestry residues including bran, chaff and mill dust, Professor Zhang Tao, Li Ning and colleagues discovered new chemical processes that can turn the waste to JP-10 fuel on a large scale with unprecedented efficiency.
