Both endothermic dehydrogenation and exothermic hydrogenation reactions are catalytic reactions. The enthalpy of reaction is very large. Moreover, the technology for the hydrogenation of benzene has already formed the industrial scale [18], which will promote the potential application of the cyclohexane/...
According to this concept, the rate of reaction of an unsaturated fatty acid in a triglyceride molecule does not depend on the chemical nature of the other fatty acid moieties in this molecule. The concept greatly simplified the understanding of what happens during a hydrogenation reaction and ...
Vacuum furnaces have the advantages of high temperature, low pressure, and uniform heating. Materials in the vacuum furnace are not affected by oxidation, hydrogenation, nitridation, and other factors, so the quality of the materials after heat treatment is more stable and pure. In addition, the...
By dynamic technique, the dependence of adsorption and surface reaction rate coeffients for alpha-methyl styrene hydrogenation on the properties of active sites of Pd/Al2O3 catalyst was studied. The results showed that there were two kinds of active sites on the surface of Pd/Al2O3. Their ...
A composition of the present invention can be a semi-solid or wax-like material. The state of the composition will depend on the degree of hydrogenation, which is measured by the IV. The hardness or softness of the material may be a result of the level of hydrogenation. Thus, when a ma...
Suitable wall thickness may depend on the diameter of the tube. The central space may be completely blocked at the downstream end. The outer space may be completely blocked at the upstream end. The catalyst may be supported on the plurality of metal structures. The catalyst may be supported ...
hydrogenation of aromatics, demetallization. The chemical treatments according to the invention also comprise selective hydrogenations of acetylenes and/or diolefins, dehydrogenation reactions, for example of butene to butadiene, of propane to propylene, or dehydrogenation of other paraffins (for example ...
Melt-spun magnesium alloys that contain catalytically active constituents have become attractive hydrogen storage materials due to their ultra-fine and homogeneous microstructure and their excellent (de-)hydrogenation characteristics. However, their heat conduction properties have to be improved for practical ...
Furthermore, the LOHC compounds are stable over time and do not undergo any particular deterioration throughout the various hydrogenation/dehydrogenation cycles. Over the years, many studies have been carried out on different types of compounds identifiable as a LOHC, such as Benzene/Cyclohexane and ...
(top)), will depend on the quantity of waste heat energy a data centre produces. This in turn will affect the flow rate of the ambient Irish air (Figure 1 [bottom]), to provide the vertical farm with its desired operating conditions. Figure 1. Heat exchange system that transfers the ...
