a vacuum pump, a sturdy vessel rated for whatever negative pressures you will be using, and a heat source. if you evacuate the container, and heat it to the boiling point of water (or less), the damage to your zeolite would be far, far less than if you were to only use heat, and it will have a longer useful lifespan.> Date: Fri, 4 Jan 2008 23:53:48 +0000> From: [EMAIL PROTECTED]> To: sustainablelorgbiofuel@sustainablelists.org> Subject: Re: [Biofuel] Zeolite on eBay> > forgive the question, but how do you do this vacuum heating? what> kind of special hardware is required?> > On 1/4/08, Thomas Kelly <[EMAIL PROTECTED]> wrote:> > Thanks Ken,> > Tom> > ----- Original Message -----> > From: "Ken Provost" <[EMAIL PROTECTED]>> > To: <sustainablelorgbiofuel@sustainablelists.org>> > Sent: Thursday, January 03, 2008 6:52 PM> > Subject: Re: [Biofuel] Zeolite on eBay> >> >> > >> > > On Jan 3, 2008, at 10:09 AM, Thomas Kelly wrote:> > >> > >> > >> Your 150C is about 300F.
