A reactor system includes a ketopyrolysis zone in which a metal oxide catalyst reacts with a lipid feedstock to produce a renewable fuel intermediate composition. The renewable fuel intermediate composition includes a jet fuel fraction in which a non-aromatic cyclic hydrocarbon content exceeds an acyclic isoalkane content. The renewable fuel intermediate composition is hydrotreated to produce a fuel composition that includes a jet fuel component with a freezing point less than 15 C.

Methods and compositions are provided for refining natural oils and for producing high-weight esters, high-weight acids, and/or high-weight derivatives thereof, wherein the compositions are made by cross-metathesizing low-weight unsaturated esters or low-weight unsaturated acids having hydrocarbon chain lengths less than or equal to C24 with an olefin feedstock, thereby forming a metathesized product composition including high-weight esters or high-weight acids having hydrocarbon chain lengths greater than C18, wherein at least a portion of the hydrocarbon chain lengths in the metathesized product are larger than the hydrocarbon chain lengths in the starting feedstock.

A low-saturation grease composition and the use thereof. A grease composition, which comprises, based on the total mass thereof, 50-71% of grease, 25-40% of water, and 1-6% of a protein, wherein the grease has a saturation of 20-42%. A grease composition, which comprises: (1) palm oil and shea butter; and (2) liquid grease other than palm oil and shea butter, wherein the grease composition is in a solid state at a normal temperature, and has a saturation of 25-32%. The grease composition can be used for improving the juiciness, adhesiveness and chewiness of vegetarian food and improving the mouthfeel thereof, and is used for reducing water boiling loss and baking loss during cooking, or is used for increasing the food brittleness, reducing the oil precipitation rate in the food storage process, and reducing the stirring time of dough.
