The Study of Physicochemical Properties of the Yang – Na (Dipterocarpus Alatus) Oil for Use as a High Potentiality Feedstock to Produce Liquid Biofuel in Thailand

Abstract

In this study, the distilled Yang – Na oil was investigated the physicochemical properties for use as the biofuels substituted petroleum diesel oil. Gas chromatography – mass spectrometry
(GC – MS) and Fourier transform infrared spectroscopy (FT–IR) were applied to characterize the chemical composition and to prove the chemical structure of the distilled Yang – Na oil. The results indicated that the distilled Yang – Na oil is a hydrocarbon compound which is a sesquiterpene group. To study the thermal decomposition by the thermogravimetric analysis (TGA) technique revealed that the distilled Yang – Na oil has completely combustion in the rage of ~450 – 500 °C with similar to petroleum diesel oil. Furthermore, the heating values and the fuel properties of the distilled Yang – Na oil also illustrated to meet with the qualifications of liquid bio-auto fuel both the ASTM D6751 and EN 14214 standard. Thus, the distilled Yang – Na oil is one of the attractive choices for development into feedstock as an alternative liquid biofuel in Thailand due to it has a large amount, has high properties suitable, and has high efficiency for using into the diesel engine.
