“…The advantages of biodiesel over petroleum diesel fuel are a higher flash point, improved lubricity, lower toxicity, lower sulfur content and biodegradability 4,5,6) . Although biodiesel has been widely used as blended fuel with petroleum diesel fuel, however, biodiesel still has some technical problems such as oxidative stability, low-temperature performance, nitrogen oxides (NOx) emissions 7,8) and insoluble impurities causing fuel filter clogging 9,10,11) . Such problems are related to the fatty acid compositions present in the feedstocks.…”

This study examines the effect of monoglyceride content in biodiesel on the precipitate formation of BXX fuel at three different outdoor temperatures in three locations: Serpong in Banten Province, Lembang in West Java Province and Batu in East Java Province. Each location has its height of 100, 1,500 and 2,000 meters above sea-level (asl), respectively. A modified CSFT method of ASTM D 7501 was applied. Biodiesel was varied for monoglyceride contents to approximately 0.4%, 0.6% and 0.8% and mixed with petrodiesel fuel to produce B10, B20 and B30. Each sample was placed outdoors and soaked for 21 days in a 100 mL-closed separating funnel. After 21 days, each sample was then vacuum-filtered and the precipitate retained on the filter paper was then washed with petro-ether prior to drying under vacuum condition. Then, its constant weight was measured. The results showed that the amount of precipitate formed was influenced by the soaking outdoor temperature, biodiesel percentage in BXX fuel and monoglyceride content. The proposed standard (SNI 7182:2015) for monoglyceride content parameter in B100 for producing the quality of B30 equivalent to that of B20 was found to be 0.6%-mass.

Sterol glycosides (SG) are known to cause filter blocking problems in biodiesel use. The extraction and quantitative analysis of SG is difficult due to its low problematic concentration and its compatibility with biodiesel. The purpose of this study is to develop a method to quantify SG in FAME and biodiesel using gas chromatography and other equipment found in laboratories performing routine biodiesel analyses. SG was isolated from FAME using n‐dodecane, acidification and cold soaking, followed by cold centrifugation at −8 to −15 °C. The solids obtained were further separated by phase partition with a Folch wash, followed by a final n‐dodecane rinse. This solution was analyzed by GC‐FID using the operating conditions outlined in ASTM D6584. A calibration curve for SG was produced and a first order fit gave a value of r2 = 0.992. Reproducibility tests were performed on soybean FAME and B100 canola biodiesel samples spiked with SG. The recovery of SG by the new method was found to be 99 % for soy FAME with a standard deviation of 0.7 and 100 % for B100 canola with a standard deviation of 3.5 %. The reproducibility based on two standard deviations of the predicted concentration for all 12 spiked samples studied in this work was 2.4 ppm.

The Cold Flow Properties of Palm Biodiesel for Diesel Blends Mandate in Malaysia’s Highlands

Greenhouse gas emission from burnt fossil fuels in transportation leads to global warming. Therefore, biodiesel which is believed to help in reducing carbon dioxide (CO 2 ) emission has been widely used as renewable energy that will replace diesel fuel. Biodiesel of 7% in diesel or B7 has been accepted worldwide to be the automotive fuel. In the last decade, most countries that implemented biodiesel program have gradually increased its biodiesel blending ratio above 7% for economic and environmental reasons. Malaysia has also announced the implementation of B20 starting January 2020. However, the biodiesel mandate in Malaysia's highlands was maintained at B7 because of the concern on low temperature vehicle operability. This study focuses on the cold flow properties of the blended diesel fuels and the quality of the palm biodiesel for the national biodiesel program. The monoglycerides and the water content in the biodiesel were evaluated in relation to cold temperature fuel performance. Cloud point (CP) and cold filter plugging point (CFPP) of B7 diesel sold at highlands were found below the lowest ambient temperature recorded at highlands for the past 10 years. Both CP and CFPP of Euro 5 diesel were lower than Euro 2M diesel. A 41-months survey of the monoglycerides and the water contents in the palm biodiesel indicated that the palm biodiesel used in Malaysia's biodiesel mandate meets both the EN14214:2019 and the Malaysian Standard MS2008:2014 specifications. CP and CFPP of the blended fuels increase with the increase of biodiesel blending ratio. Based on the study, it is anticipated that B20 could be introduced at Malaysia's highlands without any problem.
