- ICG Heterogeneous Catalysis Performance P10-3 t-Butyl alcohol (TBA) is an important octane enhancer that is used to replace lead additives in gasoline [Ind. Eng. Chem. Res., 27, 2224 (1988)]. TBA was produced by the liquid-phase hydration (W) of isobutene (I) over an Amberlyst-15 catalyst. The system is normally a multiphase mixture of hydrocar- bon, water, and solid catalysts. However, the use of cosolvents or excess TBA can achieve reasonable miscibility. The reaction mechanism is believed to be Derive a rate law assuming: I S (P10-3.1) I+S W.S (P10-3.2) WSZ W S+I SE TBA S+S (P10-3.3) TBA SZ TBA + S (P10-3.4) (a) The surface reaction is rate-limiting. (b) The adsorption of isobutene is limiting. (c) The reaction follows Eley-Rideal kinetics I SW TBA S (P10-3.5) and the surface reaction is limiting.

Consider the film flow of a power-law fluid with parameters к and n and density p down a plate inclined at angle with respect to the horizontal. If the film thickness is H: a. Derive an expression for the resulting velocity profile v as a function of y (distance from the plate), H, K, n, g, p, and b. Sketch three representative velocity profiles (each having, for simplicity, the same maximum velocity, which in practice would mean different values of к), for n 1, and comment briefly on the important features. C. Derive an expression for the volumetric flow rate of the liquid per unit width of the plate. Check your answer against the known expression for a Newtonian fluid: Q= H3pg sin 37arrow_forward
- Q8/ Non-Newtonian fluid characterization. A non-Newtonian liquid is tested by placing it between the two concentric cylinders of a viscometer. Since the gap h between the two surfaces is very small, they may be approximated by two planes as shown in Fig.3, one surface being stationary and the other moving. The instrument essentially measures the shear stresses t (Tx)y-h needed to move the upper plate at a variety of steady velocities V. Fig.3 Opposed surfaces of a viscometer. Explain in detail how you would discover the model to which the liquid conforms-it may be either a power-law fluid or a Bingham plastic and how you could determine from the data the two parameters (such as к and n, or to and n) for either model.
