1. A method for the joint production of aviation fuel of biological origin and marine fuel of biological origin, comprising:Provide raw materials of biological origin containing fatty acids and/or fatty acid esters, and:the feedstock is hydrotreated to remove oxygen, and isomerized to obtain an alkane intermediate with a carbon number distribution in the range of C10-C20, and the hydrotreating is carried out in the presence of one or more catalysts selected from the hydrogenated metal on the support used in the hydrogenation, at a hydrogen pressure of 10-150 bar and at a temperature of 200-400 °C, and the isomerization is in the presence of one or more catalysts of the group VIII metal contained on the support used in the isomerization, It is carried out at a temperature of 200-500 ° C and a pressure of 10-150 bar, and the carriers used in isomerization are selected from silicon oxide, alumina, clay, titanium oxide, boron oxide, zirconia, which are used alone or as a mixture, andthe paraffin intermediate is fractionated into two fractions,Lighter fractions that meet ASTM D7566-20 Annex A2 Aviation Fuel specifications, andHeavier fractions that meet the requirements of the ISO 8217 Marine Fuel Standard 2017,wherein the production capacity of the lighter fraction and the production capacity of the heavier fraction are adjusted by selecting process conditions, wherein the yield of the lighter fraction is 60wt%-90wt% of the total weight of the two fractions formed, and the yield of the heavier fraction is 10wt%-40wt% of the total weight of the two fractions formed, andThe total yield of the two fractions is at least 98 wt% of the bio-derived paraffin intermediates.
