The vapor phase decomposition of furfurylidene diacetate and crotonylidene diacetate to acetic anhydride and their respective aldehydes is homogeneous, first order, and complete. The activation energy is that characteristic of the series, viz., 33,000 cal. The specific reaction rates of the two ...
[103] put forward a more detailed overall first-order reaction model, which considers that pyrolysis produces six gas components (CO, CO2, H2, H2O, C2H4 and SO2), char and tar. In this way, the composition of pyrolysis products can be calculated, and more detailed results can be obtained...

It is found at corresponding temperatures, within this large experimental error, that the heat evolved in the first‐order transition is the same on graphite and ferric oxide. 展开 关键词: Gas liquid interfaces Surface phase transitions Graphite Adsorption Liquid vapor phase transitions ...
The penetration theory solution is presented for gas absorption accompanied by a first-order chemical reaction catalysed by a species diffusing in the liquid phase. A full numerical solution was obtained for the enhancement factor, the factor by which the chemical reaction increases the rate of ...
The combustion chamber has a fire cavity (10), a fuel issuing device (12), a primary air input, a reaction gas input, a grid (14), an exhaust gas output (16) and an ash outlet (18). There is at least one first reaction gas jet (20) in the combustion chamber roof between the ...
The first-principles calculations based on density functional theory with projector-augmented wave are used to study the anisotropy of elastic modulus, mechanical hardness, minimum thermal conductivity, acoustic velocity and thermal expansion of magnesit
Since the simple birth process yields monotonic abundance trajectories, the reaction probability \(R_{\Omega }(t \, | \, n_0)\) that at time t the population size is greater than or equal to population threshold \(\Omega\) is related to the first-passage-time probability \(P_{\Omega...
Quantitative characterization of reaction behavior between La-bearing FeCrAl melt and CaO–Al2O3–La2O3-based slags and its guidance for design of mold flux Lei Fan Tian-peng Qu Cheng-jun Liu Original Paper04 June 2024 Effect of initial microstructure on microstructure evolution and mechanical pro...
In order to further elucidate the structural conformations during catalysis, we also attempted to obtain crystal structures of reaction intermediates. It has previously been shown that the lactyl-conformation of ThDP (LThDP) is stable, while the last steps of the reaction, the decarboxylation of LT...
