1. A method for the joint production of aviation fuel of biological origin and base oil of biological origin, comprising:Provide bio-derived raw materials containing fatty acids and/or fatty acid esters, and:hydrotreating the feedstock to remove oxygen and isomerizing the feedstock to make the hydrocarbon chain branches of the hydrogenated feedstock, thereby obtaining an alkane intermediate with a carbon number distribution in the range of C10 to C20, wherein the hydrotreating is carried out in the presence of one or more catalysts selected from the hydrogenated metal selected from the carrier loaded on the carrier used in the hydrotreating at a hydrogen pressure of 10 to 150 bar and at a temperature of 200-400 °C, and wherein, The isomerization is carried out at a temperature of 200-500 °C and a pressure of 10-150 bar in the presence of one or more catalysts containing group VIII metals loaded on a carrier used for isomerization, selected from silica, alumina, clay, titanium oxide, boron oxide, zirconia and used alone or as a mixture, and the alkane intermediate is fractionated into two fractions,Lighter fractions that meet Aviation Fuel Specification ASTM D7566-20 Annex A2, as well:Heavier fractions that meet the specifications of the following base oil components, including:- Saturated hydrocarbons greater than 90wt% measured using ASTM D2007;- Sulfur content of 0.03wt% or less measured using ASTM D 1552/D2622/D3120/D4294/D4927;- kinematic viscosity 100°C 1.3-3.5mm2/s measured using EN ISO 3104/ASTMD445;- kinematic viscosity 40°C measured using EN ISO 3104/ASTMD445 is 3.4-13mm2/s;- Pour point below -24°C measured with ASTM D 97;- Flash point greater than 120°C measured with ENISO2719/ASTMD93, andwherein, through selecting process conditions, the production capacity of the lighter fraction and the production capacity of the heavier fraction are adjusted, wherein the yield of the lighter fraction is 60-90 wt% of the total weight of the two fractions formed, and the yield of the heavier fraction is 10-40 wt% of the total weight of the two fractions formed, andThe combined yield of the two fractions is at least 98 wt% of the bio-derived paraffin intermediates.
