15mog steel pipe is an alloy steel pipe mainly used in petroleum, chemical, electric power, boiler and other industries.
15mog alloy structural steel pipes contain more Cr elements, so they have higher high temperature resistance, low temperature resistance, and corrosion resistance. The principle of purifying hydrogen is to pass the hydrogen to be purified into the 15mog steel pipe at 300--500°C. On one side, hydrogen is adsorbed on the wall of the 15mog steel pipe. Since the 4d electron layer of palladium lacks two electrons, it can form an unstable chemical bond with hydrogen (this reaction between palladium and hydrogen is reversible). In the palladium Under the action, hydrogen is ionized into protons with a radius of 1.5×1015m, and the lattice constant of palladium is 3.88×10-10m (at 20°C), so it can pass through the 15mog steel pipe. Under the action of palladium, the protons combine with electrons. The hydrogen molecules reform and escape from the other side of the 15mog steel pipe.
