Any chemical reaction in a closed system is shown to be described by a geodesic in a 2-dimensional manifold that can be interpreted as the equilibrium space of the reaction. We first show this in the particular cases of a reaction with only two species corresponding to either two ideal ...

We consider a new method for modeling waves in complex chemical systems close to bifurcation points. The method overcomes numerical problems connected with the high dimensional configuration phase space of realistic chemical systems without sacrificing the quantitative accuracy of the calculations. The effic...
Reaction mechanismsValence-bond theoryThe electronic mechanism for the gas-phase 1,3-dipolar cycloaddition of fulminic acid (HCNO) to ethyne is studied through a combination of modern valence-bond theory in its spin-coupled (SC) form and intrinsic reaction coordinate calculations utilizing a complete...
Examples of Endothermic and Exothermic Processes Photosynthesis is an example of an endothermic chemical reaction. In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. This reaction requires 15MJ of energy (sunlight) for every kilogram of...
of chemical exergy acts as a leading role in the whole CRS,the reaction exergy resource with a high temperature is a common exergy resource for all exergy transport units,which belong to the parallel connection frame of radiation type.In view of the above,the exergy transfer model which ...
Method of chemical reaction in the catalytic presence of a granular catalyst is carried out under conditions such that the reactants and the reaction product are gaseous at the temperature and the pressure of the reaction. The present invention also relates to a reactor that makes it possible to...

Pawelski A,Paschedag AR,Kraume M 摘要: To satisfy the diverse product quality specifications required by the broad range of polyethylene applications, polymerization plants are forced to operate under frequent grade transition policies. During the grade transition, the reactor temperature must be kept ...
