由于加氫異構(gòu)催化劑的活性組分為貴金屬，載體為弱酸性的分子篩，當(dāng)原料油中硫含量偏高時(shí)易使加氫異構(gòu)催化劑的活性金屬中毒，降低催化劑加氫/脫氫能力，當(dāng)原料油中氮含量偏高時(shí)易使加氫異構(gòu)催化劑的酸性中心中毒，降低催化劑酸性。 Becouse of the active composition of hydroisomerization catalysts is noble metal,carrier is weak acid zeolite，when the sulfur content of feedstock is too high,it will poison the active mental, so the ability of hydrogenation / dehydrogenation of the catalyst will be reduced,and when the nitrogen content is too high,it will poison the acid center,the acid of the catalyst will be reduced. |

| Because noble metal are used as the active component of hydroisomerization catalysts and weakly acidic molecular sieves are used as carrier, when the sulfur content of feedstock is high enough to poison the active mental, the ability of hydrogenation / dehydrogenation of the catalysts will be reduced; and when the nitrogen content is high enough to poison the acid center, the acid of the catalyst will be reduced. |

Becouse active ingredient of the hydroisomerization catalysts is noble metal, and the carrier is weakly acidic molecular sieves，when the sulfur content of the feedstock is too high, it will poison the active mental, so the ability of hydrogenation / dehydrogenation of the catalyst will be reduced,and when the nitrogen content is too high,it will poison the acid center of the catalyst,the acidity of which will be reduced. 幫樓主修改了一下，主要是冠詞、介詞和詞性（形容詞，名詞還是副詞）。供參考！ |
