To determine if the exothermic reaction with a decrease in entropy is spontaneous, we can analyze the Gibbs free energy change (ΔG) using the Gibbs-Helmholtz equation:
An exothermic reactor has a refractory lining and a plurality of annular nozzles mounted in said lining. Each nozzle has an inner reactant gas passage and an annular shielding fluid passage surrounding said reactant gas passage. A reactant gas is supplied from a reactant gas manifold through ...
In carrying out exothermic catalytic reactions in a single or multi-zone catalyst system (i) the feed medium is subdivided into >=2 part-streams, the first of which flows through th whole length of the catalyst system and the remaining part-stream being supplied to the system at a number ...
Propene is one of the most important chemical feedstocks and building blocks of polymers1,2,3. The oxidative dehydrogenation of propane (ODHP) is a promising pathway to synthesize propene, as it is an exothermic reaction with no thermodynamic limitation and prevents the frequent carbon deposition ...
Since in these two steps the attacking atomic hydrogens form a covalent bond first with the C8 hydrogen and later with the C1′ carbon, both steps are markedly exothermic (the computed reaction free energies changes being −58.3 and −90.9 kcal/mol) and proceed essentially without an ...
CO2hydrogenation to methanol (reaction (1)) is an exothermic reaction. It theoretically prefers low-temperature reaction condition. Because there is a kinetic limitation at low temperatures, the reaction has to be therefore operated at reasonably higher temperatures. However, at elevated temperatures, ...

(ODHP) presents an appealing alternative. This process is exothermic, allowing it to operate at lower temperatures and reducing energy requirements9,10,11. Additionally, the presence of oxygen (O2) in ODHP suppresses the coke formation on the catalysts, and thus extending their lifetime12,13. ...
The experiments show the energy difference between virtually no and full reaction is on the order of 5 percent. Differential scanning calorimetery (DSC) of statically pressed powders shows an exothermic reaction beginning at a temperature which decreases with decreasing porosity. Powder, shock ...
