aAfter the completion of the reduction process, the sample was outgassed in purified argon for 1 h at 30 °C above the reduction temperature to remove the absorbed hydrogen 在减少过程的完成以后,样品是outgassed在被净化的氩为1 h在30 °C在减少温度之上取消被吸收的氢 [translate] aoutlet water ...
题目The temperature of a gasis related to the average kinetc energyof its molecules by the formula:average K.E =张Twhere k=1.38*10^(-23) K-1 and T is the temperature in kelvin (K).The mass of an oxygen molecule is 8 times greater than the mass of a hydrogenmolecule. Two containe...
With comprehensive utilization of the LNG cold energy, the method solves the problem that in the coke oven gas low-temperature hydrogen production, the low temperature is obtained simply through pressurizing expansion resulting in consumption of a large amount of electric energy.商凡...
PURPOSE: To provide a device for generating high temperature gas in which generation efficiency of hydrogen and oxygen gases is substantially improved by having a combustion gas generated in a burner of a lower stage reburnt in a recombustor while it is ascending and having the bonding structure...

This investigation demonstrated the prospects for the development of chemical-electrochemical plants for the removal of hydrogen sulfide from sour gas and production of high quality hydrogen and sulfur at low temperatures. The anodic oxidation of sulfide ions, formed by scrubbing sour gas with sodium ...
Quenching of O() molecules both in the gas phase and on a reactor surface has been investigated in binary mixtures of hydrogen and oxygen by using the fast-flow quartz reactor and infrared emission spectroscopy. Rate constants of the O()... KS Klopovskiy,DV Lopaev,NA Popov,... - 《Jou...
A double SAW resonator system was developed as a novel method for gas sensing applications. The proposed system was investigated for hydrogen sensing. Commercial Surface Acoustic Wave (SAW) resonators with resonance frequencies of 433.92 MHz and 433.42 MHz were employed in the double SAW resonator sy...
