A gaseous reactant is absorbed in a liquid with a positive heat of absorption. It reacts with the liquid by an exothermic, irreversible first order reaction. Analysis of a CSTR for this process has shown that up to 5 steady state solutions may exist even though the system appears to be ...
1. A process for controlling the location of an exothermic reaction between two or more reactants in a cyclic reverse-flow reactor system comprising: (a) supplying the first reactant through a first channel means in a first regenerative bed and supplying at least a second reactant through ...
This model is powerful for optimizing the flow pattern of reactant gases and cooling water, in order to homogenize the relative humidity. From a general point of view, the temperature distribution inside the cell is governed not only by the local heat source rate in the exothermic reaction ...
Metals that can form intermetallic compounds by exothermic reactions constitute a class of reactive materials with multiple applications. Ni–Al laminates of thin alternating layers are being considered as model nanometric metallic multilayers for studying various reaction processes. However, the reaction ...
Most importantly, the entire chlorination process from RuN4/NC to [RuN4/NC]Cl3 is highly exothermic (Fig. 6d). That is because once the original symmetrical confinement of RuN4/NC was broken with the adsorption of the first Cl*, the subsequent chlorination process became more energy ...
To understand this effect, we first point out that it has been found previously that the interaction of several adsorbates with a spin-polarized surface is less exothermic than on the non-polarized counterparts and that adsorption reduces the spin moment of the surface33,34. The calculated N-N...
The issues associated with reagent and reactant purity, the type of Grignard reagent formed, and reaction variables need to be carefully understood and controlled. For this reason, chemists and engineers have turned to the RC1mx reaction calorimeter to measure the exothermicity of Grignard ...
Figure 1. Illustration of reaction schemes for CO2 hydrogenation to olefins, aromatics, and other hydrocarbons For the MeOH route, the first step is the exothermic reaction of CO2 hydrogenation to MeOH, followed by the MTO or MTA reaction. CO2 hydrogenation to MeOH is thermodynamically limited ...
In particular, in the catalytic synthesis of hydrocarbons from carbon monoxide and hydrogen performed in the presence of a fluid catalyst, the reaction is so highly exothermic that it is necessary to resort to cooling means to prevent undue temperature rises. Heretofore, and prior to this invention...
