In a typical test 750 mg of catalyst was added to a continuous stirred tank reactor containing the nitrate ions in 1 L of phosphate buffer solution. This suspension contained 85% H3PO4 (331 g), NaNOs (198 g), NaOH (84g), and Ge02 dissolved in water and was stirred under a H2 flow of 150 L/h. The amonnt of hyam formed and selectivity after 90 min at 30°C were measured by titration [2-3]. Catalysts A and C were also chosen for stndying the effect of Pd loading and Pt addition.

The permeability of the unloaded tube B obviously increases compared with that of platinum loaded. In figure 4, the intercept value of the line II is nearly twice as large as that of line IV (1.373 and 0.78, respectively), but the slope of line II is half that of line IV (0.00679 and 0.00344, respectively), which shows that with prolonged dipping time, the Pt loading on the membrane also increases. The pore blocking effect of Pt particles become also more serious, so that the pore size distribution of the membrane is improved.
