It's better to follow ASTM standards. Biodiesel blends made by mixing biodiesel with petrodiesel, since biodiesel miscible with any proportion of petrodiesel and may possesses several advantages over no:2 petrodiesel fuel such as lubricity, low toxicity and biodegradability. Both ASTM standards and EN standards describe the key elements in specifications for biodiesel (B100) and biodiesel blends separately and standard test methods for those specifications. ASTM D 6751 provides the specifications for biodiesel (B100) while ASTM D 7467 provides specifications for B6-B20 biodiesel blends. Usually, B6 biodiesel blend can be used, without any modification of CI engines.
Different kinds of biodiesels can be blended together. Diesel can be blended with biodiesel. In dual fuel engines you can use two kinds of fuels. Follow ASTM standards for your experiment. Go ahead.
Tharindu Madusanka Dampe Acharige Thank you, the papers you attached are useful for me, but I want to know like, I want to blend soybean oil with other types of biodiesel, based on what I can choose soybean oil blend for example with sunflower oil?
Yazan Altarazi I think you are asking, the possibilities to blend two different types of biodiesel. According to ASTM standards, blends preparation based on the mixing volumes. Producing biodiesel is also a challenge and mixing two different biodiesel would not be cost effective and also the usability of a product mainly depends on the test results which are complying the standards. The properties of the product would be unpredictable. But your product may be an efficient one too.
As a scientist you are thinking beyond the line. Keep it up.
You can choose two methods, i.e., in-tank blending or in-line blending.
1. The biodiesel suitable to blend of course that appropriate with national or international specification (ASTM D 6751 for US standard and EN 14214 for European standard)
2. The blends were verified according to ASTM D 7806 method (up to 30%-vol)
