Thermodynamically, formation of H2SO4 is exothermic; the overall reaction equation and corresponding enthalpy [7] are:(1)SO3+H2O→H2SO4ΔH=−21.5kcalmol−1 Prior studies suggest that the formation of SO3 is extremely fast and highly favored on Pt. The SO3 then interacts with metal or...
Most of the prereduction reactions are exothermic (reactions (1)–(5)); hence, the reduction will serve to preheat the charge mixture as it descends through the furnace. CO2 is produced by the prereduction reactions and from carbonates in fluxes or ores. CO2 produced at temperatures above ...
The reformer's reactions are endothermic; thus, a significant amount of energy is needed, especially when the reactor is set to a high temperature. On the other hand, no additional energy is needed to operate the WGS reactor as the WGS reaction is exothermic and the heat required to ...
uunnddeerr 5500 bbaarrooff HH22inin The endothermic reaction, which can be seen in Figure 2a before the absorption (exothermic event starting at 280 °C), may be associated with the fusion of some LiBH4, residual or initially formed, or to the changes in the thermal conductivity of the ...
