Production of aviation mixture from renewable sources with high aromatics
A recently granted patent (Publication Number: US12012560B2) outlines a method for producing an aviation mixture using renewable sources. The process involves receiving a renewable stream rich in aromatic compounds obtained from converting vegetable oils, animal fats, and fatty acid esters in a fluid catalytic cracking unit. This renewable stream is then mixed with a stream of fossil kerosene and fed into a reactor with hydrogen and NiMo sulfide catalyst supported on alumina. The resulting aviation mixture contains at least 8% aromatics and is produced under specific conditions of pressure, temperature, and space velocity.
Furthermore, the patent describes a method for producing an aviation mixture using a combination of renewable diesel, vegetable oil, and bioaromatic compounds sourced from renewable sources. The mixture is homogenized and fed into a reactor with a system catalyst comprising hydrogenation and hydroconversion catalysts. The resulting aviation mixture also contains at least 8% aromatics and is produced under specific pressure, temperature, and space velocity conditions. The system catalyst includes a combination of hydrogenation catalysts like NiMo, CoMo, NiW, or Mo sulfides supported on various materials, and hydroconversion catalysts based on NiMo, NiW, Ni, Pt, Pd, or PtPd prepared with specific supports containing zeolites.
