Performance And Emission

Fossil fuel is getting exhausted at a fast rate and contributes to high carbon monoxide emissions. Biodiesel, being environmentally friendly, has better performance than diesel. Castor oil is an easily available vegetable oil in India. But its high viscosity leads to blockage of the fuel lines. The amount of free fatty acid more than 1% leads to soap formation which necessitates the biodiesel production in a two step process. The first step of acid catalyzed esterification process reduces the free fatty acid content of castor oil to below 1%. The second step of transesterification process converts the preheated oil to castor biodiesel. This two step process gave a maximum yield of 90%.The methyl castor oil (biodiesel) is blended with diesel in different proportions on volume basis as 15:85 (B15), 25:75 (B25), and 35:65 (B35). These blended oils are used to run a single cylinder four stroke compression ignition engine with different coatings of pistons, to study and compare the engine performance and emission characteristics at different load conditions.

Biodiesel from a high free fatty acid (FFA) mixed crude palm oil (MCPO) can be produced to high fatty acid methyl ester (FAME) conversion by a two-step process. The first process is an acid-catalyzed esterification to reduce FFA in oil followed by a base-catalyzed transesterification process to produce biodiesel from esterified oil. In this study, the transesterification of esterified oil with methanol in the presence of potassium hydroxide (KOH) was performed in a 1,000 W ultrasonic homogenizer at a low frequency of 18 kHz. The use of high-intensity ultrasound to accelerate the reaction, the high surface power density of 1.62 W.mm-2 and the volumetric acoustic energy of 20 W.mL-1 were fixed. The objective of this study was to determine the various parameters (methanol concentration, KOH concentration, and initial temperature of oil) to produce the FAME conversion. The results showed that over 98 wt.% of FAME could be achieved with 5 g KOH/liter of oil, 15 vol.% of methanol, the total residence time of 20 seconds, and temperature of 30 oC. Moreover, the glycerides were rapidly converted to the FAME within reaction time of 10 seconds when the base-catalyst of 10 g KOH/liter of oil, and 20 vol.% of methanol were used. Consequently, the use of high-intensity ultrasonic irradiation can minimize the chemical cost, electricity cost, and reaction time.
