According to foreign media, American scientists said they have found a way to use discarded corn husks and straw to make cheap hydrogen fuel that does not pollute the environment like fossil fuels. According to a report from AFP on April 6, a report published in the monthly "Journal of the National Academy of Sciences" states that the research team of the Virginia Institute of Technology saves time and money, and the zero-emission fuel produced can accelerate the development of hydrogen-powered vehicles. Zhang Yiheng, a professor of biological system engineering at the Virginia Polytechnic Institute and one of the authors of the study, said: “We have shown that the most important step towards the hydrogen economy is to use local biomass resources to produce cheap, green hydrogen.†The person in charge was Joe Rolling, Ph.D., a former Ph.D. student at Virginia Polytechnic Institute, Zhang Yiheng. They both co-founded a cell-free bioinnovation company. According to the report, the study drew on previous research using xylose. Xylose is the most abundant plant monosaccharide. Other hydrogen fuel production methods rely on deep-processed sugar, but Virginia Tech's research team uses corn husks and straw called dirty biomass to reduce costs and make the fuel easier to produce locally. Rollin discovered that the decomposition of corn stalks and straw into hydrogen and carbon dioxide can use both glucose and xylose instead of using them separately. This discovery means that the release rate of hydrogen can be accelerated, and at the same time, the plant area needed to produce hydrogen can be reduced to the size of a gas station. Rolling pointed out: "We think this exciting technology is expected to make hydrogen fuel vehicles universal and replace fossil fuels throughout the world." According to a report on the UK’s “Isle of Independents†website dated April 6, scientists have significantly increased the efficiency of using plant wastes to produce clean hydrogen fuel. This breakthrough will one day lead to the “bioreactor†where gas stations are supplemented by roadside vehicles. The network replaced. A study funded by Shell Petroleum Co. shows that it is possible to convert all sugars stored in corn waste, including corn stalks and loquat leaves left after harvesting in corn fields, into hydrogen without increasing emissions to the atmosphere. The total amount of carbon dioxide. Zhang Yiheng, a professor at Virginia Polytechnic Institute, said that the researchers optimized the extraction process by mixing raw agricultural waste with an aqueous solution containing 10 enzymes. This solution converts the xylose and glucose contained in the plant into hydrogen and carbon dioxide. Previous processes used fermenting microorganisms or industrial catalysts and could only convert 30% to 60% of sugars in plants into hydrogen. However, Zhang Yiheng said that the latest technology converts 100% of plant sugar into hydrogen. He said: “The products taken out by this process are all gases, so they can be easily separated from the biomass matrix and collected. Throughout the process, the carbon value of this process is constant, and we make the reaction rate It has increased 16 times, making it economically viable."
Polypropylene
fiber by polypropylene and a variety of organic and inorganic materials,
refined by special composite technology, products can be formed in the concrete
three-dimensional supporting role to the distribution of the mesh, the micro
cracks formed at the beginning of the hardening concrete was blocked in the
process of development, to develop further. Thus, it can improve the fracture
toughness of concrete and improve the anti-seepage properties of concrete. It
is a new ideal material for mortar, concrete engineering, anti-cracking,
anti-seepage, wear-resisting and heat preservation.
The anti-cracking ability of the non-structural crack in the
plastic stage of concrete is improved.
It is a kind of effective rigid self-waterproofing material.
The range of noil is 0.6-1.8 kg/m3, and the concrete
anti-cracking anti-seepage is usually 0.9kg/m3.
Main functions: to prevent concrete cracks, improve the
permeability resistance of concrete, improve the freezing-thawing resisting
performance of concrete, improve the impact resistance of concrete, folding
resistance, fatigue resistance, seismic performance, improve the durability of
concrete, aging resistance, improve the fireproof performance of concrete.
