加氫脫氮

The hydrodenitrogenation(HDN) performance of the molybdenum carbide catalyst was evaluated by using 5% pyridine/cyclohexane as a model reactant. 以吡啶/環(huán)己烷溶液為模型化合物,在高壓微反裝置上評(píng)價(jià)了碳化鉬催化劑的吡啶加氫脫氮性能。

The dibenzothiophene hydrodesulfurization and carbazole hydrodenitrogenation activities of catalysts were tested on a high pressure micro-reactor. 通過(guò)高壓微反對(duì)催化劑的二苯并噻吩加氫脫硫和咔唑加氫脫氮活性進(jìn)行了評(píng)價(jià)。

Under the high pressure condition,the catalyst shows excellent hydrodenitrogenation activity and stability for heavy fraction oil such as Iran VGO. 在高壓條件下,本研究催化劑對(duì)重質(zhì)餾分油如伊朗VGO等原料油具有優(yōu)良的加氫脫氮活性和穩(wěn)定性。

Except for heavy Iran VGO,both hydrocracking and hydrodenitrogenation properties and qualities of relative products are superior to or similar to those of the Shengli VGO. 除伊重VGO外,其加氫脫氮、加氫裂化性能和相關(guān)產(chǎn)品性質(zhì)均優(yōu)于勝利VGO或與勝利VGO相當(dāng)。

The catalytic activity and selectivity for hydrodesulfurization(HDS) and hydrodenitrogenation(HDN) were studied by using benzothiophene(BT), dibenzothiophene(DBT) and quinoline as model compounds. 實(shí)驗(yàn)結(jié)果表明，升高反應(yīng)溫度和壓力均提高催化劑的加氫脫硫、加氫脫氮活性；
