A carbon catalyst obtained from glycerol , a byproduct of biodiesel processing, with a high density of sulfonic acid groups is prepared by carbonization and sulfurization (see figure). The carbon catalyst, with very good water tolerance and reusability, is useful for the preparation of biodiesel from fatty acids or from fatty acids present in vegetable oils and animal fats.
