HomeBrewStuff Actvated Charcoal Carbon 1lb for Filtering Spirits

Would this be left behind in a distillation? ie- distill once, dilute to 50% abv, add carbon and let sit, then distill a 2nd time to remove carbon.

Is this an appropriate charcoal for making my own coffeepot water filters?

Is this wood, stone, or coconut carbon?

How do I use this?
