Whats So Different about Biodiesel Fuel? - Penn State Extension Biodiesel molecules consist almost entirely of chemicals called fatty acid methyl esters (FAME), which contain unsaturated "olefin" components Low-sulfur petroleum diesel, on the other hand, consists of about 95 percent saturated hydrocarbons and 5 percent aromatic compounds ¹
Chemistry-bio fuels-comparing biodiesel and petrodiesel Both petrodiesel and biodiesel are not pure substances as the hydrocarbons that form each fuel vary in size When petrodiesel and biodiesel burn in excess oxygen they produce carbon dioxide and water
Biodiesel - an overview | ScienceDirect Topics Diesel fuel from petroleum (petrodiesel) consists of about 75% saturated hydrocarbons, including branched isomers, plus 25% aromatic hydrocarbons The majority of molecules range in size from 12 to 15 carbons
QUESTION 1 - TSFX Saturated molecules are more likely to be found in petrodiesel, which is primarily composed of alkanes Many triglycerides contain at least one carbon to carbon double bond and therefore, the fatty acid esters produced are likely to be unsaturated QUESTION 6 Biodiesel has higher viscosity and therefore flows less easily through fuel lines
Petrodiesel vs Biodiesel* Flashcards - Quizlet - Biodiesel is biodegradable, because it is able to is more likely to react with atmospheric oxygen and be broken down by bacteria and fungi - This means that biodiesel can not be stored as long as petrodiesel and must be stored with quality seals and fuel hoses
