    • Algae oil feeds comprise a wide range of molecular species forming a complex mixture of molecules having varying sizes and therefore varying boiling points, comprise high nitrogen, oxygen, and fatty acid content, but comprise low sulfur, saturated hydrocarbons, and triglycerides. The wide range of molecular species in the algae oil feeds, very unusual compared to conventional refinery feedstocks and vegetable oils, may be upgraded into fuels by conventional refining approaches such as thermal and/or catalytic-hydroprocessing. Hydrotreating at high pressure over large-pore catalyst, and optionally followed by FCC cracking, has shown a beneficial product slate including coke yield. Thermal treatment prior to hydrotreating may improve hydrotreating feedstock quality. Unusual behavior of the algae oils in thermal treatment and/or hydroprocessing, including cracking to lower boiling range compounds, may provide a high quality product slate with the flexibility to adjust the product slate due to the cracking behavior exhibited by these algae oils.
    • 藻类油料饲料包括广泛的分子种类,形成具有不同大小,因此变化沸点的分子的复杂混合物,包含高氮,氧和脂肪酸含量,但包含低硫,饱和烃和甘油三酯。 与常规炼油原料和植物油相比,藻类油进料中广泛的分子种类可能通过常规的精炼方法如热和/或催化加氢处理而升级为燃料。 在高压下在大孔催化剂上加氢处理,随后进行FCC裂解,已经显示出有益的产品,包括焦炭产率。 在加氢处理之前的热处理可以提高加氢处理原料质量。 藻类油在热处理和/或加氢处理(包括开裂至较低沸点化合物)中的不寻常行为可以提供高质量的产品板岩,具有由于这些藻油所显示的裂纹行为而调整产品板岩的灵活性。
