Can someone please point how to use sodium bentonite for water removal from methanol (and or oil) and how to regenerate it for reuse?
What sort of conditions did I need to I create and results I should expect?
Thats a good question, hasn't been used for that yet except for some simple testing with wvo water removal, so I say give it a try and report back to us!
As far as reuse, simply dry out and if it is too clumpy just break it up with a hammer. Ta Da!
I haven't tried yet, but I think you could either set up some sort of column like is used for any dry washing method, but you would have to account for a lot of expansion of the bentonite.
Or you could go a more passive route and just make a sock full of bentonite on a rope to drop into the tank of methanol or WVO. Again, though, taking into account the nature of swelling that bentonite has, so use a very stretchy material for the sock, make sure you choose a size you can get back out the hole you drop it into, even if it swells, say, 300% (just a guess).
I finally found a local source I can walk right onto the shop floor and just buy the stuff, so if I ever get around to getting over there to get some, I will be able to start figuring out some of these more nitty-gritty details.
