The usage of vegetable oil as a fuel source in diesel engines is as old as the diesel engine itself. Regardless, the enthusiasm to make and utilize plant oils and creature fats as biodiesel has been obliged up to these years and now has been into utilization. In this paper the part of starch: Amylose is used as a precursor for the generation of Biodiesel. Several hydrothermal carbonization methods have been compared and the results show that there are significant differences in terms of surface areas, porosity and the surface functionality of the catalyst samples at several stages of its preparation. The best outcome in 150 min at 120o C gives the qualities as: 136.15 m2/g for surface area and 0.54 cm3/g as pore volume, with the acid density value around 20 mmol/g after sulfonation. It is inferred that amylose gelatinization and its transformation to mesoporous structure is amazing. Once the mesoporous structure of the catalyst is formed the material treatment procedures at later stages, such as solvent exchange, drying and pyrolysis, require very cautious thoughtfulness to maintain the porosity while changing its physical and chemical conditions. The surface functionality, measured by Fourier Transform Infra-Red Spectra, of the synthesized materials at different stages will be compared and discussed. The activity and stability of these mesoporous acid catalysts for esterification of oleic acid as a probe reaction for biodiesel synthesis will be presented.
