| Figure 1 and 2 show that 0.6wt‰ amount of iron existed on the fresh catalyst, which is from the raw materials for preparation of catalyst. The Fe component on the fresh catalyst has no negative effect on the hydroisomerization reaction, since Fe locates in the catalyst support bulk with an inert state. The Fe content after reaction increases remarkably to more than 1.2 wt‰, e.g., 2Kh and 8Kh in Figure 1 and 2. All the Fe species adsorbed during reactions locates on the catalyst surface with reduced or oxidized states. These Fe components on the surface will have a series of complicated negative effects on the surface acidic sites and metallic sites, or even plug the pores of catalysts after long time enrichment of Fe from reagent oils. Further more, the solid Fe deposits on the catalyst can hardly be removed no matter by reductive or oxidative treating method. So Fe species in the reagent oils must be removed before reaction. |

[ 感謝獎賞 ] Because of the way it's prepared, fresh catalyst is held intact and protected especially on the outside by inert steel. That outside layer (0.6wt‰ as shown in Fig's 1 and 2) keeps acidic and metallic sites, especially those on the surface available for reaction. Access to those sites can be reduced, sometimes completely if reactive iron were allowed to accumulate or even plug surface pores of the catalyst. The catalyst can become useless once hydroisomerization or unchecked long-term contact with iron-rich reagent oils more than doubles superficial iron to 1.2 wt‰, or to 2Kh and 8Kh in Figures 1 and 2, respectively Since solid iron deposits are nearly impossible to remove, reagent oils must be rid of its iron content as much as possible [prior to reaction] in order to preserve the catalyst. 附注: - 潤色目的是要比原文更易讀,更能吸引讀者, LZ 原意我已由外入內(nèi),更故事化的表達(dá)了 - 不要突換動詞時態(tài),除非談及實驗當(dāng)時,否則一貫現(xiàn)在式最好 - 并非 "Figure 1, Figure 2" 不可, "Fig's 1 and 2" 縮寫也行 - "with reduced or oxidized states" 表示帶電,易產(chǎn)生反應(yīng)(即 "reactive"  - "can hardly be removed no matter by ..." = "nearly impossible to remove" - 預(yù)計"support bulk" 原意是 "保持完整" = "keep intact" - 翻譯假設(shè)活性點(diǎn)越難進(jìn),催化劑就越不中用 |
