The present invention relates to a process for producing ethyl esters of polyunsaturated fatty acids, comprising transesterifying triacylglycerols in extracted plant lipid.

The present invention relates to extracted plant lipid, comprising fatty acids in an esterified form.

A reactor system includes a reactor that treats a lipid feedstock using a metal oxide catalyst to produce a treated stream comprising a bio-oil. The reactor system includes a catalyst zone in which the metal oxide catalyst reacts with the lipid feedstock to produce the treated stream. The reactor system operates in a reaction mode, during which the lipid feedstock flows in a downward direction through the metal oxide catalyst to produce the treated stream. Alternately, the reactor also operates in a regeneration mode, during which coke is burned from the metal oxide catalyst thereby regenerating the metal oxide catalyst. In one aspect, a regeneration mode pressure is less than a reaction mode pressure within the reactor to fluidize the catalyst.

Some phthalates are considered toxic and carcinogenic, which limits their use and demand for safer and more environmentally friendly plasticizers. The development of plasticizers produced from vegetable oil derivatives with a high degree of unsaturation is described, which allows the production of esters with a high epoxy content, guaranteeing excellent performance in terms of plasticization, high compatibility with polymeric materials such as polyvinyl chloride, polyesters, nitrocellulose, thereby avoiding migration when used in polymeric matrices. Fatty materials produced from linseed or tung oil have a high degree of unsaturation compared to vegetable oils such as soybean, corn, peanut, canola, sunflower; however, they are scarce and expensive when compared to them. we start Starting from common oils such as soybean and similar oils and separate the saturated part, generates materials with a high degree of unsaturation similar to fatty materials derived from linseed oil.
