Hi,

 

is it normal for catalysts to lose platinum on recovery, and if so, by how much?

 

the process is dehydrogenation of alkanes and operating temperature and pressure are well below those that cause formation of volatile platinum oxide (i.e. T and P are not as significantly high as nitric acid production process, where volatile PtO2 formation is a major source of platinum loss).

 

after recovering platinum (the company that recovers it applies 2% loss from sample result), only about 93% of Pt from the initial amount that has been used to make the catalyst is recovered. im not expecting 98% recovery from the initial amount of Pt, but i would like to know possible sources of platinum loss in this whole process that would result in more than 2% loss.

 

Thanks.
