Solid acids are conventional materials that have wide applications in chemical prodution. In this work, a kind of solid acid catalyst for preparing biodiesel was produced with polysaccharid and glucose. First the natural products, such as starch or sugar, were incompletely carbonized to get a rigid carbon material composed of small polycyclic aromatic carbon sheets. Then the sulphonite groups were introdued by liquid sulphuric acid. The black powder obtained was in soluble in water, methanol and biodiesel. At last Esterification and transeterification of soybean oil and methanol on this catalyst to prepare biodiesel was studied.
