Application of an Efficient Nonconventional Heterogeneous Catalyst for Biodiesel Synthesis from Pongamia pinnata Oil
نویسندگان
چکیده
Recycled chicken eggshells after calcination have been used as a nonconventional heterogeneous catalyst for biodiesel synthesis from karanja oil from the pongam tree (Pongamia pinnata). The catalyst was characterized on X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and differential thermal analysis/thermogravimetric analysis (DTA/TGA). The formation of the calcium oxide phase was confirmed at 900 C after calcination. A high biodiesel yield of 95.0% and conversion of 97.4%was obtained at an 8:1 (alcohol/oil) molar ratio, 2.5 wt%catalyst, and 2.5 h reaction time at 65( 0.5 C. The biodiesel conversion was determined by Fourier transform nuclear magnetic resonance (FTNMR) spectroscopy.

Preparation of biodiesel from crude oil of Pongamia pinnata.
Biodiesel was prepared from the non-edible oil of Pongamia pinnata by transesterification of the crude oil with methanol in the presence of KOH as catalyst. A maximum conversion of 92% (oil to ester) was achieved using a 1:10 molar ratio of oil to methanol at 60 degrees C. Tetrahydrofuran (THF), when used as a co-solvent increased the conversion to 95%. Solid acid catalysts viz. Hbeta-Zeolite, ...

Biodiesel is obtained by processing edible and non-edible oils. Due to the increase in demand for fuel and stringent emission norms, biodiesel is preferred as it meets the emission norms. To meet the exponentially growing demands in developing countries, continuous production is required which can be achieved by mechanical screw presses. Currently, single screw press is being widely used for ex...

Biodiesel is an alternative fuel for diesel engines that is produced by chemically reacting vegetable oil or animal fat with an alcohol such as ethanol or methanol in the presence of catalyst. The growing interest in biodiesel (fatty acid methyl ester or FAME) is because of the similarity of its properties when comparing with diesel fuel. Karanja (Pongamia pinnata), which is one of the source o...
