Viscosity modeling and flow properties of non-edible oils as feed-stock in biodiesel production

n a previous study, non-edible plant seeds were sought as sources of vegetable oils as alternatives to soybean oil which
is the major source of oil feedstock for the manufacturing of biodiesel in the United States of America. Soybean oil as a
resource also doubles as a staple food: it is the most widely consumed cooking oil (frying, baking and a condiment in salads).
Commercially, soybean oil is also used in printing ink and oil paint formulations. Hence the motivation for the search for other
oil sources especially for the non-edible/non-staple sources. In this study, several plant seeds which were selected based on
their ease of cultivation and short maturation periods were investigated for the yields, densities and the degrees of saturation
and compared to the soybean output as a benchmark. A further investigation is undertaken in the present study to compare
the viscosities and the Cloud Point (CP) temperatures of the benchmark soybean oil and the non-edible oils that compared
favorably to the soybean oil in terms of the yields and Iodine Values (IV). Different mathematical models were applied in the
fitting of the measured viscosity data. However, since the models did not adequately represent the data in the region of interest
(lower temperatures), a new mathematical model was developed which in combination with measured data were used to infer
the Cloud Point temperatures of the oil samples. The inferred Cloud Point temperatures ranged from -17
o
C for the Lavender
oil to 8
o
C for the Morning Glory oil. For the benchmark oil (Soybean), the Cloud Point temperature was inferred to be 0
o
C.
Therefore, most of the sample oils had Cloud Point temperatures lower than for the benchmark which confirms these oil
candidates as possible replacements of the benchmark.
Biography
Okafor graduated from the Ohio State University with a Ph.D in Nuclear Engineering in 1988. He is currently a professor of Nuclear Engineering at the South
Carolina State University where he teaches courses in nuclear sciences and engineering. His areas of interest include Reactor Physics, Nuclear Criticality Safety
and Renewable Energy. Prior to coming to South Carolina State University he worked at the Savannah River Laboratory (SRL) in Aiken, SC under Dupont and
Westinghouse companies (facility operators) involved in research and development in reactor analysis and technical support in the handling and storage of nuclear
materials.
