Familiarize yourself with the hydrogen
A hidrogén a legegyszerűbb és leggyakoribb elem az univerzumban. Ez a víz, az olaj, a földgáz és minden élő anyag egyik fő összetevője. Egyszerűsége és bősége ellenére a hidrogén ritkán fordul elő természetesen gázként a Földön. Szinte mindig más elemekkel kombinálódig. Elő lehet előállítani olajból, földgázból és biomasszából, vagy a víz megújuló nap- vagy elektromos energiával történő felosztásával. A hidrogén olyan energiahordozó, amelyet más forrásokból előállított energia mozgatására, tárolására és szállítására használnak.
The hydrogen on Earth as it is widespread, but in the universe is the most frequently occurring element. (the universe is the material of approx. 75(m/m)%of hydrogen) are Present in the water, almost all of the organic compound and the biomass.
The hydrogen, the only one proton and one electron from an element is the simplest and easiest diatomic gas. Earth is our greatest quantity in bound form, especially in the water is located. The periodic table of elements, the first element of Henry Cavendish discovered nearly 250 years. Normal condition is a colorless, odorless, yes flammable and very good thermal conductivity. The normal state of the air at a density of about 14 times smaller, it's also very significant to the diffuzivitása, i.e. very well and quickly got lost.
Since the properties of many aspects of positive – non-toxic, non-corrosive, no carcinogens, no greenhouse, no radioactive, if it accidentally gets into the environment, will not cause any permanent environmental pollution and calorific value of the known elements is one of the highest – researchers and engineers regiment are now working around the world to the potential exploit.
The hydrogen countless area be used as an energy source and as a fuel, the energy distribution and dominant play a role in the future.
The hydrogen application is not new, as close to 250 years is used in the chemical industry about 100 years ago, extensively applied. In the world today, there are nearly 80 million tons of hydrogen are produced annually in Hungary more industrial hydrogen production facility works e.g. of the százhalombatta, Kazincbarcikai in Budapest. Typically, the ammonia production, oil refining and many other industry use, but the industrial gas works company of routine operations as they are producing hydrogen, although in significantly smaller quantities.
The hydrogen laboratory production of the traditional and the school is also often presented in ways that, when zinc hydrochloric acid is poured. Then, hydrogen gas evolves and zinc chloride is formed:
Zn + 2HCl = ZnCl2 + H2
Well-known may be the method, when some alkaline metals such as sodium and water reaction, are reported. In this case, the intense reaction in hydrogen gas is generated:
2 can + 2H2O = 2NaOH + H2
The industrial-scale, large amount of hydrogen production is not the above reactions are used. Hydrogen is very much in the materials occur, in principle, so very many ways that can be produced, but the current practice is absolutely dominant method in fossil fuel starting production. Within this dominant from natural gas, more precisely, of methane (CH4), happened hydrogen production. The latter method gőzreformálásnak also known as the English abbreviation: SMR (Steam methan of Reforming).
