Residence time reaction order
WebA batch reactor will just keep on reacting until the reaction mixture is removed and further processed. It is necessary to compare the conversion between a batch reactor and PFR. The residence time of about 10 minutes was chosen to compare the batch reactor and the PFR. From Figure 6 it is clear that the PFR has a conversion of about 80%.

WebStep response In the step-response experiment, at time zero we abruptly change the feed tracer concentration from steady value c 0 to steady value c f. For convenience we assume c 0 = 0. Because the feed concentration is constant at c f after time zero, we can take it outside the integral in Equation 8.3 and obtain WebThis problem has been solved!
