Thermal Balance in the Dewar Vessel

This approach consists in measuring the adiabatic temperature increase of a sample taken at the outlet of the reactor. Samphng is made in an adiabatic vessel (Dewar vessel) and temperature is recorded until the reaction ends, that is, until an equilibrium temperature is reached. The conversion rate is thus written as 

Temperature difference in the reactor was less important than in the Dewar vessel because of the efhdent exchange with the utility stream. That is the reason error estimation in the reactor is higher than in the Dewar vessel. 

Finally, the oxidation reaction has to been run under strict conditions of temperature, which are impossible to be operated in a batch reactor. Indeed, utility stream in the Shimtec reactor was heated to 47 °C, which first initiates the reaction, accelerates its kinetics, and then controls the temperature when the heat of the reaction is too important. In a batch reactor, working with such UF temperature is impossible because of security constraints. It would certainly lead to a reaction runaway. We now consider this question in the next section.
