We observe from Figures 4 and 5 that velocity and temperature profiles increase with the increasing values of [lambda] for exothermic reaction, but opposite effects are found in these figures for endothermic reaction. It is observed from (1) that increasing temperature frequently that causes a marked increase in the rate of reactions is shown in Figure 4.
The results of DSC tests show that the particles with larger sizes absorb more energy during endothermic reaction before its thermal decomposition.
When the pyrolysis gas recirculation was increased from 0.0011 [m.sup.3]/s to a maximum of 0.0021[m.sup.3]/s at a constant primary air flow rate of 0.00083 [m.sup.3]/s, the maximum temperature in the combustion zone decreased from 1273[degrees]K to 1148[degrees]Kbecause the endothermic reaction that produces [H.sub.2] (reactions (3)) became more dominant.
Substitution doping of [Eu.sup.3+] ion was an endothermic reaction. There is no apparent phase transition endothermic peak of AlOOH [right arrow] [gamma]-[Al.sub.2][O.sub.3] in the temperature range of 773 K to 1173 K.
The cracking of ammonia leading to the production of hydrogen is on the other hand an endothermic reaction (16).
This result is expectablebecause the dehydration of tincalconite is an endothermic reaction.The r-square values obtained from DTA- TGA curves fit a first order kinetic model.
However, CDRM is strong endothermic reaction with high energy consumption, and catalysts are easy to deactivate due to carbon deposition.
Since the Tg signifies the transition of the polymer from a glassy solid to an elastic phase, the transition involves a drop in enthalpy and shows up in the DSC curve as an endothermic reaction.
It was concluded that the flame resistance mechanism of LCPs can be attributed to the endothermic reaction at the ester linkage rupture process, char formation and diluting oxygen by evolution of C[O.sub.2] prior to the evolution of flammable gaseous products.
For the sample with much more surface group, the heat of endothermic reaction was greater.
Furthermore, isocyanate can react with itself at high temperatures in an endothermic reaction that produces carbodiimide and carbon dioxide.
