24、ove, is regis-tered with the U.S. EPA as a fuel and a fuel additive underSection 211(b) of the Clean Air Act. There is, however, otherusage of the term biodiesel in the marketplace. Due to its EPAregistration and the widespread commercial use of the termbiodiesel in the U.S. marketplace, the term bi

25、odiesel will bemaintained for this specification.3.1.1.2 DiscussionBiodiesel is typically produced by areaction of a vegetable oil or animal fat with an alcohol such asmethanol or ethanol in the presence of a catalyst to yieldmono-alkyl esters and glycerin, which is removed. The finishedbiodiesel de

26、rives approximately 10 % of its mass from thereacted alcohol. The alcohol used in the reaction may or maynot come from renewable resources.3.1.2 biodiesel blend (BXX), nblend of biodiesel fuel withdiesel fuel oils.3.1.2.1 DiscussionIn the abbreviation BXX, the XX rep-resents the volume percentage of

32、cified shall conform to the detailedrequirements shown in Table 1.NOTE 2A considerable amount of experience exists in the U.S. witha 20 % blend of biodiesel, primarily produced from soybean oil, with80 % diesel fuel (B20). Experience with biodiesel produced from animalfat and other oils is similar.

33、Experience with B20 and lower blends in otherapplications is not as prevalent. Although biodiesel (B100) can be used,blends of over 20 % biodiesel with diesel fuel (B20) should be evaluatedon a case by case basis until further experience is available.NOTE 3The user should consult the equipment manuf
