  • Method for the production of biodiesel from vegetable oils and fats, using heterogeneous catalysts
    Publication number: 20080295393
    Abstract: The invention relates to the field of methods used for the transesterification of oils and fats in order to produce diesel oil. The invention provides a novel method for the production of diesel oil by transesterifying fatty acid esters present in vegetable oils and fats, using a novel catalyst consisting of the oxide of a group V metal and having the formula X2O5, such as niobium pentoxide (Nb2O5). Unlike in the methods used traditionally according to the prior art, the oils are converted here into high-purity products, including glycerol, in yields of the order of 100%, while using significantly less catalyst for a quantity of oil processed, when e.g. soya-bean oil, cotton-seed oil and canola oil are processed by the method according to the invention.
