请教个问题，磷Ｐ元素对加氢精制催化剂有影响吗? 谢谢楼上各位，这真是个有趣的事情，两种对立观点并存，一种认为磷有助催化加氢，一种认为毒害催化剂。我想这是不是跟磷的化合物形态有关？ 我昨天问了一下催化剂的厂家，回复如下： both ca and p are catalyst poisons - ca is a mild poison and p more of a moderate poison. phosphorus in reduced form would likely also poison hydrotreating catalysts. my guess is under the reducing conditions of hydrotreating phosphorus would prefer nickel or cobalt sites over molybdenum, tungsten, or aluminum. p that comes in with the feed is likely to be a catalyst poison which blocks an active site. 即催化剂厂家的观点还是认为毒害催化剂，但似乎也不是100%确定。 还请更多的同志们参与详解。查看更多
