What is the potential potassium source?
I’m testing a steam reforming catalyst, feeding water through a vaporizer to get superheated steam that vaporizes an isooctane feed. The mix vapor is fed over the catalyst. Recently my steam feed line completely plugged up with solidified potassium compounds, and the entire group has no idea where potassium might have come from. The water is ultra-pure (18.2MΩ-cm), the tubing is all 316 stainless, the isoocatne is reagent grade, and the tracer gas feed is UHP N2. Anybody have any ideas? The water reservoir is just an HDPE jug, flowing through an HPLC pump with a 15 micron filter on the outlet. Anybody ever seen potassium contamination before that can help me out?

Check out your filters. If they are glass, you get various salts mixed in on them, maybe some dust. This would have taken a LOT of filters to happen though. I don’t believe it myself, but check it out.
