Renewable Energy Group Publishes “Feedstock and Biodiesel Characteristics Report”
… The goals of this project were to produce biodiesel from a wide variety of feedstocks and to provide the characteristics of both the feedstock and biodiesel. The project is unique because it encompasses an extensive range of feedstocks and all feedstocks were pretreated, esterified, and transesterified using the same procedures and conditions allowing for uniform comparisons of critical fuel properties.
In this report, 36 feedstocks were evaluated and biodiesel was produced from 34 of them. These feedstocks varied from traditional fats and oils to novel feedstocks from around the world. The feedstocks used in the study were: algae (2 samples), babassu, beef tallow, borage, camelina, canola, castor, choice white grease, coconut, coffee, distiller’s corn, Cuphea viscosissima, evening primrose, fish, hemp, high IV and low IV hepar, jatropha, jojoba, karanja, Lesquerella fendleri, linseed, Moringa oleifera, mustard, neem, palm, perilla seed, poultry fat, rice bran, soybean, stillingia, sunflower, tung, used cooking oil, and yellow grease. Jojoba and karanja were tested for feedstock quality but not made into biodiesel.
Each feedstock was tested for the following characteristics: moisture, free fatty acid, kinematic viscosity, FAC color, saponification value, moisture and volatile matter, insoluble impurities, unsaponifiable matter, MIU, oxidation stability, sulfur, phosphorous, calcium, and magnesium.
