請[化學]專業人員翻譯

以下是同學在面試種踫到的句子，好像跟化學品相關。
請高手指點該如何翻譯？
謝謝

Please note that what you mention about deposit is engine deposit but the NIOC experts believe that there is a great possibility that the metal contents deposit in EXHAUST CATALYST. Please comment on this.

请注意你所提到的沉淀物是机器的沉淀物,但是NIOC的专家相信在排气催化剂中很有可能就是含有这种金属沉淀物. 请注意这一点.

请注意你提到的沉积物是发动机沉积物，但NIOC的专家相信在排气催化剂中很大可能含有金属成分的沉积物。请对此看法发表意见。

是不是汽车行业？

好像是化學品相關的。

估计是  专家怀疑 尾气催化剂中含有杂质导致沉积
