CO 氧化的空速SV比较,求指点?在我们的固定床CO氧化反应中,文中描述是这样的:100 mg powder was loaded in a stainless tube reactor, and the reactor was heated from room temperature to 600 ºC at a rate of 2 ºC/min. The total gas flow rate was 40 ml/ min corresponding to a space velocity (SV) of 24000 mL g-1 h-1, and the inlet gas composition was 1 % CO and 5 % O2 with N2 as balance. 在这个体系下我们做了几个材料对CO的催化反应,主要考察在不同温度下的CO转化率,并与其他人类似的材料做了比较,无非是想说明我们的材料活性更好。但审稿人提出了这个问题:The selected experimental conditions are very favourable for CO oxidation, as large excess of oxygen and more importantly rather low space velocities have been used. About the concern of space velocity my concern was more general. We are looking at the process of CO oxidation. In this respect the comparison should be made with state of the art system and not just with similar materials.看其他人的文献,其实我们的空速也不低啊,1:5的CO:O2也不算高,审稿人的意图到底想表达什么呢?恳请行家指点!查看更多5个回答 . 3人已关注
