The present invention provides a novel glycerol-based heterogeneous solid acid catalyst by simultaneous partial carbonization and sulfonation of crude glycerol obtained as a by-product during the biodiesel process. Solid acid catalyst with similar activity is also prepared from glycerol pitch (by-product of fat splitting) and technical grade glycerol. These glycerol-based solid acid catalysts are employed for esterification of fatty acids and fatty acid present in the high and low free fatty acid (FFA) containing vegetable oils like rice bran, karanja and jatropha; fatty acid distillate; deodorizer distillate and acid oil which are being used as raw materials for the preparation of biodiesel. These catalysts are highly active, reusable and simplify the biodiesel process particularly for fatty acids or high FFA containing vegetable oils by replacing the traditional homogeneous mineral acid catalysts.

The present invention relates to a simple and economically attractive process for the pretreatment of vegetable oils which involves (a) enzymatic degumming with commercially available phospholipase Afrom the sources likemicroorganism, (b) bleaching of the enzymatically degummed oil using bleaching earth and activated carbon, and (c) dewaxing (in case of rice bran oil) of degummed and bleached oil at lower temperature to obtain oil with less than 5 ppm of residual phosphorus which is amenable for physical refining.
