All of the pilot plant tests were made at 60 liquid volume percent per pass conversion below the recycle cut point. Temperatures were adjusted as necessary to maintain this conversion. Total pressure and recycle gas rate were held constant for all of the runs with a given feed.

Catalyst Activity. Fig. 3 shows the results of the catalyst activity test. The reaction was carried out at standard conditions consisting of a mean catalyst bed temperature of 538°C, atmospheric pressure and LHSV of 2h.

THE PROBLEM A batch laboratory reactor with an electrolyte volume of 700 cm and an electrode area of 30 cm is used to deposit a divalent metal from an aqueous solution in a potentiostatic mode. Initial concentration of the metal is O.lkmol/m. The reactor mass transfer coefficient has been measured as 3.3 x 10" m/s. Hydrogen evolution occurs as a parallel reaction according to the equation % = H p [ — ], where kn = 1.30 X 10" A/m and = 12 If the metal deposition is operated at its limiting current density at an electrode potential of —0.9 V (SCE), determine how conversion, total current density, and current efficiency vary with time, in a potentiostatic mode. What will be the current efficiency at the final...

Alternatively, appearance of the failure surface is indicative of the nature of fracture and may be used in transition temperature determinations. For ductile fracture, this surface appears fibrous or dull (or of shear character), as in the steel specimen of Figure 8.14, which was tested at 79°C. Conversely, totally brittle surfaces have a granular (shiny) texture (or cleavage character) (the —59°C specimen in Figure 8.14). Over the ductile-to-brittle transition, features of both types will exist (in Figure 8.14, displayed by specimens tested at -12°C, 4°C, 16°C, and 24°C). Frequently, the percent shear fracture is plotted as a function of temperature-curve B in Figure 8.13.
