I tried to make the stuff from cotton without the Nitrogen. I did the pyrolysis and the sulfonation for half the time. I guess I was too impatient. I tested it with WVO with 12% FFA. After treatment, the FFA content went down to only 5%. To make sure that it wasn't the leftover acid that was doing the job, I'm doing another run, using the same sample I made. Then I will try to transesterify both runs.

Hot concentrated sulphuric acid lacks appeal. _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
