H2O2 Synthesis: Effect of Pressure. The pressure changes the gas solubility; it can also affect the hydrodynamics. It has been studied observing the H2O2 production rate and selectivity, replicating some of the previous experiments (at 10 bar) at 20 bar, always at -10 °C. Results at 20 bar are reported in Figures 7 and 8, for productivity and selectivity, respectively. They must be compared with Figures 4 and 5 for results at 10 bar. Note that the higher pressure requires a larger mass flow rate to achieve the same volumetric gas flow rate, because of a higher density. Production rate (Figure 7) behaves similarly to the case of 10 bar (Figures 4), with a clear maximum with respect to the gas flow rates. The lowest liquid flow rate used (0.5 mL/ min) results in the maximum productivity, slightly smaller than that obtained at 10 bar, unexpectedly, given the larger concen- tration of reagents determined by a higher pressure. We can also observe that the higher pressure shifts the maximum of productivity to lower gas flow rates, but the shift decreases with higher liquid flow rates. This may simply reflect that data arebetter comparable in terms of equal gas mass flowrates. At the same time, the role of pressure with small gas flow rates is tosupport an increase of production rate.
一段化工专业英语~有人帮我翻译一下吗?
财富值不够多呐,呵呵。科技文献的翻译挺麻烦,要严谨和正确。另看了其他两个人的翻译,很不准确啊。第一句就翻译错了。The pressure changes the gas solubility; 一个翻译成:“压力气体的溶解度变化”, 另外一个翻译成“气体的溶解度的压力变化”,明显是在乱翻译嘛,都没理清句子的结构和含义。...
