Abstract
Crude algae oils produced by practical extraction techniques comprise a wide range of molecular species that can be characterized by advanced analytical techniques. The algae oils comprise a complex mixture of a large number of molecules having varying sizes and therefore varying boiling points, and comprise high nitrogen, oxygen, and fatty acid content, but low sulfur, saturated hydrocarbons, and triglyceride content. Hydrogen/carbon molar ratios are typically greater than 1.6. The wide range of molecular species in the crude algae oils, while unusual compared to conventional refinery feed stocks and vegetable oils, may be upgraded into fuels by conventional refining approaches such as hydrotreating and thermal treatment. Unusual behavior of the algae oils in thermal processing and/or hydrotreatment may provide a high quality product slate, with the flexibility to adjust the product slate due to enhanced cracking behavior exhibited by these algae oils.
