1. method from renewable raw materials production hydrocarbon product stream, described hydrocarbon product stream comprises the hydrocarbon of boiling point in the aviation fuel scope, and described method comprises:

  • A) in the presence of hydrogen and under reaction conditions, contact by the one group of catalyzer that makes renewable raw materials and polyfunctional catalyst or have hydrogenation, deoxidation, isomerization and a selective hydrogenation cracking function, in reaction zone, make renewable raw materials hydrogenation, deoxidation, isomerization and selective hydrogenation cracking, the reaction that comprises water, oxycarbide, light hydrocarbon gas, hydrogen and paraffinic hydrocarbons ejecta is provided;

    B) water, oxycarbide, light hydrocarbon gas and hydrogen are separated the liquid stream that generation comprises paraffinic hydrocarbons from the reaction ejecta;

    C) materials flow that will comprise paraffinic hydrocarbons separates the hydrocarbon product that generation comprises the hydrocarbon of boiling point in the aviation fuel scope;

    Comprise the overhead product materials flow of petroleum naphtha;

    With comprise the bottom stream that boiling point is higher than the component of aviation fuel boiling spread;

    AndD) reclaim hydrocarbon product stream.
