What does weak chemisorption mean?

TL;DR Summary

How come silver having a weak chemisorption of olefins means it is a good olefin/paraffin separator?

I am reading a research paper that says weak chemisorption of silver with olefins basically means more effective olefin/paraffin separation. If silver weakly binds to olefins, wouldn't that make a lousy separator?

The opposite is true taken in its proper content. You see...
In general solid materials have "weak" surface energy distribution sites (that is probably what is confusing you), where vapor molecules or gas can adhere to or bonded with the help of a catalyst commonly heterogeneous catalyst. Through a technique using the chemical absorption phenomena.
"Chemisorption".
But I should have asked what research paper are you referring to?
In any event. I hope this helps it's a good read.

Given the information this is probably a stretch.The material used to bond to silver is more than likely,but I could be wrong, vaporized using the sputter technique in a vacuum.
