Hydrodesulfurizer, tracer data

Normalized tracer response data for a packed bed hydrodesulfurizer are tabulated.The time will be found at which 75% of the tracer has left the vessel. The fraction of the tracer that has exited the vessel is represented by the integral of the last column. Interpolating, E(tr) - 0.75 when tr = 1.05. 

Tracer impulse response data of a commercial hydrodesulfurizer are given by Sherwood (Course in Process Design, 1963) and are given in the first two columns. Various response functions will be found. 

Data of tracer impulse input to a hydrodesulfurizer are cited by Sherwood (1963) and listed in the first two columns. The following functions are derived. 

Tracer impulse data of a commercial hydrodesulfurizer (Sherwood, A Course in Process Design, MIT Press, 1963) with 10 mm catalyst pellets are given in the following table.
