Renewable jet fuel composition having a high content of naphthenic compounds and associated preparation method

Abstract

The present invention relates to a jet fuel composition obtained from renewable feedstocks comprising, relative to the total volume of the composition: a. from 50 to 90% by volume of at least one paraffinic base obtained from a hydrotreatment of esters and fatty acids, from a Fischer-Tropsch process or from a process for the production of jet fuel from alcohols, and which comprises at least 90% by weight of paraffins relative to the total weight of the paraffinic base, b. from 10 to 50% by volume of at least one C8-C16 naphthenic base, said naphthenic base being obtained from hydrogenation of a C8-C16 aromatic base, said aromatic base corresponding to the C8-C16 fraction of a biofuel produced by a process for converting at least one C1-C6 bioalcohol into fuel, and said aromatic base containing at least 60% by weight of aromatic compounds relative to the total weight of the aromatic base, said aromatic compounds comprising at least 50% by weight, preferably at least 80% by weight of benzene substituted by at least m methyl(s), m being an integer from 1 to 3, and optionally n C2-C5 alkyl(s), n being an integer from 1 to 3, wherein said jet fuel composition comprises from 10 to 49% by weight of naphthenic compounds relative to the total weight of the composition.
