Cp) is 9.6 s. The breakthrough curve appears to be symmetric. Assume the hydrogen does not adsorb and that pore diffusion controls methane mass transfer. 

Figure 5.43 shows calculated breakthrough curves in a steam reformer of a naphtha-based ammonia plant with no prereformer [387] [389], The relative concentration of hydrogen sulphide at the tube exit is...
