Because hydrogen is the only neutral atom for which the Schrödinger equation can be solved analytically,[11] the study of its energetics and chemical bonding has played a key role in the development of quantum mechanics. Hydrogen gas was first artificially produced in the early 16th century by...
such as surface exchange (steps 2 and 4) andbulk diffusion(step 3), when the gas phase resistance can be neglected. How the surface exchange and bulk diffusion affect the transport process is reflected in the permeation flux equation expressed below[27]: ...
Before 1940 most of the world production of hydrogen was made by processes based on coal or coke, the principal one being awater–gasreaction between steam and red-hot coke: H2O + C → CO + H2. By 1970, however, relatively little hydrogen was being produced by such processes. For many...
using the electrolytic method of concentration discovered by Edward Wight Washburn. Whenwateriselectrolyzed—i.e., decomposed by anelectric current(actually a watersolutionof anelectrolyte, usuallysodiumhydroxide, is used)—the hydrogengasproduced contains a smaller fraction of deuterium than the remaining...
The adsorbed ions can produce hydrogen gas by two mechanisms: electrochemical desorption that involves an ion–atom reaction, combining with protons in the acidic solution according to the Heyrovsky reaction (Equation (13)) or a combination of two adsorbed hydrogen atoms on the surface of the ...
“decarbonized” hydrogen from oil and gas depends on capture and storage of the CO2produced4,30, and on the associated upstream methane leakage4,31,32,33. Secondly, since the indirect hydrogen impact on climate involves chemical reactions in the atmosphere, the uncertainties on key processes ...
chemical kineticsdetonationAn approximate two-stage kinetic model of the chemical reaction in hydrogen-oxygen mixtures containing hydrogen peroxide, water, and inert diluents is developed. The model includes one differential equation for the calculation of the molar mass of the gas after the induction ...
is the chemical potential of the sorbed molecules, nmsthe number of hydrogen molecules per binding site and µmis the chemical potential of the hydrogen gaseous molecules. By utilizing the ideal gas approximation, the chemical potential in the gaseous state can be given by the following equation...
Industrial by-product hydrogen production is the industrial tail gas rich in hydrogen as raw materials, mainly using pressure swing adsorption (PSA) method to recover and purify hydrogen. This technology is mainly used in iron and steel, chemical industry, and the main sources include coke oven ...
