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.
