    • PROBLEM TO BE SOLVED: To provide a method for producing paraffinic hydrocarbons by hydrotreatment of a feed from renewable sources such as vegetable oils.SOLUTION: The flow of the total feed for treatment is subjected to a pre-treatment process comprising pre-hydrogenation of the feed material in a solid bed having a porosity of 0.25-0.8 and containing a catalytic solid material which is mixed or not mixed with a non-catalytic solid material; a hydrotreatment process to divide the pre-treated product into a prescribed number of different part flows equal to the number of the catalytic zones in a reactor, and inject the different part flows in the hydrotreatment catalyst zones to produce an effluent containing paraffinic hydrocarbons; and a separation process to enable separation of the hydrotreatment effluent into a gas fraction and a liquid fraction containing the paraffinic hydrocarbons. At least a part of the liquid fraction is recycled to the pre-treatment process or at least one of the catalytic zones, and the weight ratio of the recycled flow and the partial flow injected in the first catalyst zone is ≥10.
    • 待解决的问题:提供通过从诸如植物油的可再生来源进料的加氢处理来生产链烷烃的方法。 解决方案:用于处理的总进料的流动进行预处理过程,其包括在孔隙率为0.25-0.8的固体床中进料的预氢化,并且含有混合的催化固体材料 不与非催化固体材料混合; 将预处理产物分成等于反应器中催化剂区数的规定数量的不同部分流的加氢处理方法,并将不同的部分流注入加氢处理催化剂区以产生含有链烷烃的流出物; 以及能够将加氢处理流出物分离成气体馏分和含有链烷烃的液体馏分的分离方法。 将至少一部分液体馏分再循环至预处理过程或至少一个催化区,并且再循环流和注入第一催化剂区的部分流的重量比≥10。 版权所有(C)2013,JPO&INPIT
