Sentence examples for conversion variations from inspiring English sources
Detection of spatially resolved NMR spectra was used to characterize chemical conversion variations within the operating reactor.
The conversion variations are almost constant with increasing agitation speed or decreasing catalyst volume, implying the presence of nonsignificant external and internal mass transfer resistance on the catalyst surface and within the catalyst structure.
This method minimizes error arising from densitometric conversion, variations in BMD by anatomical location and pathology of bone, and allows for subject-specific material mapping, and density-modulus relationship development.
The conversion variation under this condition without stirring is 37.8% (selectivity, 92.4% to cyclohexylbenzene, 7.6% to bicyclohexyl).
Figure 4b shows the conversion variation versus catalyst volume plot obtained under the same conditions as the stirring speed test.
A theoretical model was developed that satisfactorily agrees with the obtained experimental results, thus allowing the prediction of the conversion variation with the pervaporation time.
Figure 4a shows the conversion variation versus rpm plot for 200 atm of CO2 containing 10 atm of H2 obtained at 50°C and 5 min over 5.1 cm3 of a Pd/m-HDPE catalyst, as shown in Figure 2c.
The conversion variation is almost constant with decreasing catalyst volume, implying a nonsignificant internal mass transfer resistance within Pd/m-HDPE catalysts because of the CO2-swollen HDPE support and the microcellular structure contributing to the facile inner mass transfer.
As a result, two different plateaus were observed on the conversion distribution plot: between 28 and 38 µm and between 50 and 56 µm (the corresponding conversion variation in these regions was below 0.05).
The conversion variation test to compare agitation speed or catalyst volume was performed as follows: a small beaker containing 10 μL of biphenyl stock solution in hexane (concentration = 7.74 × 10-2 M) was placed on top of Pd/m-HDPE catalysts in a 20-mL high-pressure reactor.
The relative contributions of back mutation and gene conversion to variation at the six diagnostic positions are examined, and cases of complete forward gene conversion events are reported.
