从废铂重整催化剂和铂粉尘中回收铂,对于节约贵金属具有重要意义。我国石油工业突飞猛进地向前发展,石油重整催化剂的需要量与日俱增。催化剂在长期使用后,由于经高温、高压同烃类原料接触,会慢慢地被毒害钝化,含碳物沉积在催化剂活性位置上,使催化剂失活。此外,石油烃中的有害杂质也会使催化剂中毒。因此,失活的催化剂不能继续使用。其中一部份可以经过烧焦,补氯等措施再生更新后又用。无法再生者需要回收。
The recovery of platinum from waste platinum reforming catalyst and platinum dust is of great significance for saving precious metals. The petroleum industry in our country advances by leaps and bounds and the demand for catalysts for the reforming of petroleum increases with each passing day. After long-term use of the catalyst, due to contact with the hydrocarbon raw materials through high temperature and high pressure, it is slowly poisoned and passivated, and the carbonaceous material is deposited on the active site of the catalyst to deactivate the catalyst. In addition, harmful impurities in petroleum hydrocarbons can also poison the catalyst. Therefore, the deactivated catalyst can not be used any more. Some of them can be charred, chlorine and other measures renewable regeneration and use. Those who can not regenerate need to recycle.
