2. The following sketch illustrates the gas-phase diffusion in the neighborhood of a catalytic surface. Hot gases of heavy hydrocarbons diffuse to the catalytic surface where they are cracked (i.e. decomposed). LMA N NL P H Where p is the crysta Z = 0 Obtain a. Expresalon sub valuate baled on exp sivity Gsdering thet ths Z = 8 Figure 2 By reaction H → 3L The light products diffuse back into the stream. a. Reduce the general differential equation for mass transfer to write the specific differential equation that will describe this steady-state transfer process if the catalyst is considered a flat surface. b. Repeat (a) for a cylindrical, catalytic surface
