CO 氧化的空速SV比較,求指點(diǎn) 已有2人參與

在我們的固定床CO氧化反應(yīng)中,文中描述是這樣的: 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. 在這個(gè)體系下我們做了幾個(gè)材料對(duì)CO的催化反應(yīng),主要考察在不同溫度下的CO轉(zhuǎn)化率,并與其他人類似的材料做了比較,無非是想說明我們的材料活性更好。但審稿人提出了這個(gè)問題: 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. 看其他人的文獻(xiàn),其實(shí)我們的空速也不低啊,1:5的CO:O2也不算高,審稿人的意圖到底想表達(dá)什么呢?懇請(qǐng)行家指點(diǎn)! |

| 審稿人認(rèn)為你做的東西沒有先進(jìn)性,也就是沒有挑戰(zhàn)性,別人做了什么,你也跟著做了,沒有體現(xiàn)出你的創(chuàng)造性來!要你與最先進(jìn)的比較,而不是別人的比較!你可能碰到了一個(gè)對(duì)這個(gè)體系有相當(dāng)研究的審稿人,你對(duì)這個(gè)體系很了解,也許他就在做這個(gè)工作,自己做的還不錯(cuò),所以看看別人的東西都看不上眼!你找點(diǎn)創(chuàng)造性出來可能比較好! |
