I am interested in investigating the resistances affecting catalytic reactions such adsorption, surface reaction, mass transfer etc and i need recent publications on that which i have not been able to get. Thanks
I don't think you find a general paper on it, only in catalytic kinetic textbooks. What I assume you're after is the rate determining step remaining with the catalyst keeping in mind that a catalyst reduces the homogeneous rate limiting step by lowering the activation energy of the reaction. Each reaction and catalyst is different so you would have to pick the specific case and see if anyone explored the rate determining steps over the conditions you are interested in.
Diffusion of reactants in and out of the pores of a heterogeneous catalyst (considering the Question I presume you have that) can be very important and perhaps even rate-determining. From my own education I remember the concept of the 'Thiele-modulus' that gives information in this respect. Try to search that in textbooks or at the internet (scienceweb of ScienceFinder)?
There are 7 steps in a catalytic reactions. External diffusion Internal Diffusionadsorptionsurface reaction on catalytic surfacedesorptioninternal diffusionexternal diffustion. Thiele modulus represents the magnitude of pore diffusion resistance combined with surface reactions. Smaller Thiele modulus, lower the resistance to diffusion(i.e shorter pore, slow reaction, rapid diffusion).

Let's start by specifying the issue. So a scheme of chemical reaction or chemical reactions (should be linearly independent). Then the stoichiometric analysis (definition of conversion degrees, concentrations of reactants), possibly thermodynamic data (equilibrium constants, reaction enthalpies) and finally the mass and energy balances for the grain. It is also worth remembering about simplifications. Intraparticle diffusion is usually considered (second order ordinary differential equation/equations) and interparticle energy transport (boundary condition) in modelling. Of course you can also use the so-called. dusty gas model to describe the mass transport (Knudsen diffusion, multicomponent molecular diffusion and viscous flow) - but it's up to you.
And do not forget about the kinetic equation/equations.
