Alternatives to molecular sieve
I ran across a reference to using tapioca pearls as dessicant for ethanol. Seems that the crystalline starches in the outer layers of the pearl have a very good affinity for water. They can be regenerated and also used as a starch feedstock once depleted. Seems like a neat technique.
Study finds more effective way to dry ethanol, reduce costs

I guess you might need this if making fuel ... Seems like a waste of good whisky to me

Re: Alternatives to molecular sieve
I find that article very interesting and informative. You never know when you might have the need to dry out some alcohol.
U have a half gallon of 95+% I don't have any plans for, maybe I'll get some tapioca pearls and see what they do

Re: Alternatives to molecular sieve
I don't think it's as easy as chucking the pearls into cold likker, but I have plenty of feints to experiment with so I thought I'd give it a try and see what happens. There were none in our pantry or our local supermarkets. They are so out of fashion here that no stores in our town stocks them.

Re: Alternatives to molecular sieve
I've got 400g of small pearls in the pantry. When I get around to a feints run, I'll try 'em.
I just glad someone found something to do with these other than that bubble tea crap.

My wife uses them to make seedless blackberry pie that has the texture of blackberries without the seeds.

The 5 percent water hurts nothing for engines.
I think it is a waste of time for most applications to drive that last bit off.
Burn it!!!!
