A gas-phase hydrogenation reaction was studied using a catalyst fine enough to avoid any effect of pore diffusion. The rate equation is: For the following gas compositions, sketch the concentration gradients for -a A, H2, and B for the case where the reaction is rapid enough to make PAave 10% less than PA. Assume DA = 14DH2 4.6 A gas-phase hydrogenation reaction was studied using a catalyst fine enough to avoid any effect of pore diffusion. The rate equation is: A + 2H B I= KPAPH (1 + 12PB) a. For the following gas compositions, sketch the concentration gradients for A, H, and B for the case where the reaction is rapid enough to make PA 10% less than P. Assume D = DB = DH 4 Case 1 PA = 1 atm PB = 0 PH2 = 2 atm Case 2 PA = 1 atm PB = 0.5 atm PH2 = 1.2 atm b. Estimate the effectiveness factors for the two cases.
