The following endothermic and exothermic reactions
were observed; dehydration of adsorbed water (85 - 110 [degree]C), goethite dehydroxy lation (295 - 350 [degree]C), kao linite dehydroxylation (500 - 560 [degree]C), and kaolinite recry stallization (930 - 1002 [degree]C).
R' methacrylates, however, give off a lower level of heat during the exothermic reaction
than methyl methacrylates.
Third, scale up from laboratory extruder to production unit can be heat transfer limited for highly exothermic reactions
75, and 1:1 showed an exothermic reaction
at 150[degrees]C, resins with eq-MRs of 1:2 and 1:3 exhibited exothermic peaks at 185[degrees]C, and resins with an eq-MR of 1:4 presented an exothermic peak at 180[degrees]C.
Because the heat of oxidation reaction is generated within the liquid steel, heat transfer efficiency from exothermic reactions
should be nearly 100%.
Excessive thermal stabilization above 300[degrees]C, on the other hand, is reported lo cause violent exothermic reactions
, results in significant weight losses and low carbon yield of the resulting carbon fibers [12, 14].
Due to exothermic reactions
during increasing temperature goes up to 1600[degrees]C
This is because the Ni-Ti alloy absorbed the latent heat from the exothermic reactions
at the melting point (1310[degrees]C).
The product of the Prater number, which is positive for exothermic reactions
, and the intrapellet Damkohler number essentially represents a ratio of the rate of thermal energy generation due to chemical reaction relative to the rate of thermal conduction (i.
in kraft pulping arise mostly from the neutralization of native wood acids and the neutralization of acids that form during the cook as carbohydrates and lignin are degraded.
The gas-to-gas heat exchanger, or recuperator, recovers heat generated from the exothermic reactions
that take place over the catalyst beds by transferring heat from hot gases exiting the converter to the cooler gases that are entering it.
N0150 diaphragm pumps can be customized with water-cooled heads to prevent pump overheating in process applications where exothermic reactions
from helium, xenon, and other gases may produce excessive heat and potentially shorten pump service life.
