In the production of bio-diesel and glycerol from the transetherification of jatropha oil with methanol in the presence of silica gel as the catalyst, I want to know if there is a catalyst that can separate the glycerin from the bio-diesel without the conventional method of allowing the heavier liquid to settle or the application of centrifugation?
Have an insight or suggestion?

Re: Is there a catalyst that can separate glycerin?26 January 2009 at 1:29pmI am not aware of such a catalyst. I am not sure I understand the question. Glycerol will form with the bio-diesel. Glycerol and bio-diesel are insoluble. The fact that they can phase separate in a conventional decanter is good.
