(EN) A process for producing a diesel fuel, characterized by fractionating in a first rectifier a synthetic oil obtained by the Fischer-Tropsch synthesis method into at least two fractions, i.e., an intermediate fraction and a wax fraction containing a wax ingredient heavier than the intermediate fraction, bringing the intermediate fraction into contact with a hydroisomerization catalyst to hydroisomerize the fraction and thereby obtain an isomerized intermediate fraction, bringing the wax fraction into contact with a hydrocracking catalyst to hydrocrack the fraction and thereby obtain a cracked wax fraction, fractionating the isomerized intermediate fraction and the cracked wax fraction in a second rectifier to fractionate these fractions into at least two fractions comprising a kerosine fraction and a gas oil fraction, and mixing the at least two fractions in a given proportion to obtain a diesel fuel having a dynamic viscosity as measured at 30 DEG C of 2.5 mm2/s or higher and a pour point of -7.5 DEG C or lower.
(ZH) 本发明涉及一种柴油燃料的制造方法，其特征在于：在第1精馏塔中将用费-托合成法得到的合成油分馏成中间馏分、和包含比该中间馏分重质的石蜡组分的石蜡馏分这至少两个馏分；所述中间馏分通过与加氢异构化催化剂接触进行加氢异构化，形成异构化中间馏分，所述石蜡馏分通过与加氢裂化催化剂接触进行加氢裂化，形成石蜡裂化组分，在第2精馏塔中分馏所述异构化中间馏分和石蜡裂化组分，分馏成包含煤油馏分和粗柴油馏分的至少两个馏分，通过按规定比例混合所述至少两个馏分，得到30℃时的运动粘度为2.5mm2/s以上、且流动点为-7.5℃以下的柴油燃料。
