The two catalysts supported on USY zeolites with surface acid amounts of 626 and 203μmol/g, respectively, showed excellent sulfur tolerance, while the catalysts of higher and lower acid amount showed decreased sulfur tolerance. Energy dispersive spectroscopic analysis proved that the support with a large acid amount adsorbed more sulfur, which might lead to the lower sulfur tolerance of the catalyst.

结果表明硫含量为200μg/g时，载体酸量为626和203μmol/g的两个催化剂的耐硫性最好，而载体酸量更低和更高的催化剂的耐硫性较差，表明载体的酸量太大或太小都不利于催化剂的抗硫性。X射线能量散射分析表明，酸量大时S在酸性位吸附很多，这可能导致催化剂中毒。
