Technical Abstract: Field pennycress (Thlaspi arvense L., FP) is a winter annual species of the mustard family (Brassicaceae) which is widely distributed throughout temperate North America that can serve as a winter rotational crop for conventional crops, thus not displacing farm land or negatively impacting the food supply. FP seed contains 36% oil by weight, which is high in erucic acid, with linoleic, linolenic, oleic, and gondoic acids also present in significant quantities. Biodiesel prepared from FPO (FPME and FPEE) displays excellent cold flow properties, relatively poor oxidative stability, and relatively high kinematic viscosity versus soybean oil methyl and ethyl esters (SME and SEE). Comparison to ASTM D6751 reveals that FPME and FPEE are satisfactory with respect to all parameters measured here. Viscosity, methyl linolenate content, and oxidative stability do not meet the stated requirements in EN 14214, but blending or treatment with antioxidants are likely to ameliorate these deficiencies. Blends of FPME and FPEE in petrodiesel compared favorably to an analogous set of SME and SEE blends and were satisfactory after comparison to ASTM D975 and ASTM D7467. In conclusion, FPO has excellent potential as an alternative biodiesel feedstock.
