Abstract: In this study we have developed synthetic methods for preparation acid carbon materials from available precursors such as heavy oil fraction, sulfuric acid and different templates (for example rice husk). The main advantage of our way of preparation is cheap precursors and easy variation of acid content in material and value of specific surface. Obtained composites were characterized by BET, SAXS, TEM and they are also tested in catalytic activity (esterification fatty acids reaction). The catalytic properties and durability of the obtained materials studied in the esterification reaction. Esterification of higher fatty acid was carried out at 80 °C in an ethanol–oleic acid (C17H33COOH) mixture (ethanol, 0.10 mol; oleic acid, 0.010 mol) under Ar atmosphere. Total density of the composite acid sites can be estimated via sulfur element analysis, because each sulfonic acid group constitutes a potential acid site. Elemental analysis data are well consistent with results on irreversible titration by pyridine solution
