The Introduction of Crystallographic Strain in Catalysts by Hydrodynamic Cavitation

After the analysis was completed, the plot was used to predict the processor conditions required to synthesize the point of highest strain in the figure of 0.44%. A power law fit of the data showed that the microstrain was more sensitive to changes in the Reynolds number, but the strain decreased as the Reynolds number increased. Over the regime studied, the microstrain increased as the cavitation number decreased for aT = 0.5 to 1.8. 

Several series of methanol synthesis catalysts were prepared by the coprecipitation of the appropriate metal salts in either Na2C03 or (NH4)2C03 using the CaviPro 300 (dual-orifice processor) at both high and low pressures. The experiments were carried out using a 0.152-mm first orifice while varying
