PRODUCTION OF LOW REDUCED AROMATIC JET FUEL FROM SUNFLOWER OIL – KEROSENE MIXTURE

摘要

In the recent past the properties of gasolines and diesel gas oils were continuously severed, and theproperties of jet fuels will be more severe, too. Furthermore, it can become obligatory to blend alternativecomponents into jet fuels. Based on the abovementioned, now the possibilities of producing low aromatic and lowsulphur content in heterogeneous catalytic way are studied worldwide. One of the possibilities is the blending ofbiocomponent from catalytic hydrogenation of triglycerides. The aim of our experimental work was to study thecatalytic transformability to jet fuel of 30-70% Russian crude oil originating from a previously desulphurizedkerosene fraction and a Hungarian gardened sunflower oil mixture at different process parameters. Based on theexperimental results in case of the studied feedstock the yield and the properties of the products were favourable atthe following process parameter combinations: temperature 320-330°C, pressure 50 bar, LHSV 1.5-2.0 h~(-1) andvolume ratio H_2/HC volume ratio 500 Nm~3/m~3. Based on the quality properties of the product mixtures wedetermined that we successfully produced products with a high yield that have a reduced aromatic content, theirperformance properties are excellent and they contain biocomponents. These are excellent jet fuel blendingcomponents (smoke point: 35-37.5 mm; aromatic content: ≤2.0%), they damage the environment less.
