Process for the desulfurization of a fraction of diesel, diesel dessulfurizado and apparatus for desulfurization of diesel oil fraction.Process for the desulfurization of a fraction of diesel oil according to the invention comprises a step of hydrogen gas of low boiling fraction (I) where a fraction of dieselThe low boiling point is dessulfurizada under the condition that a relation of H ~ 2 ~ / oil of 70 200 nm ^ 3 ^ / KL, to produce a treated oil.A step of hydrogen fraction of diesel of high boiling (II) where a fraction of diesel of high boiling is dessulfurizada under the condition that a relation of H ~ 2 ~ / oil 200 800 nm ^3 ^ / KL, to produce a treated oil, and a step (III), where the treated oil obtained in step (I) is mixed with the treated oil obtained in step (II), and in this process.At least a part of gas containing hydrogen is not reacted in step (II) is used for the hydrogen of step (I).According to the invention, may be provided with a process and a device for desulphurisation of a fraction of diesel oil.Which are capable of using hydrogen and energy efficiently and capable of producing a highly dessulfurizado diesel in a small catalytic amount.According to the invention, still, a diesel dessulfurizado, which is produced economically and has a sulphur content of sufficiently reduced can be provided.According to the invention, even more, can be equipped with a device for desulphurisation of a fraction of diesel, which is capable of using a hydrogen gas and energy efficiently.Can be simplified in its construction, capable of reducing the cost of the equipment, control equipment, the maintenance work, the area of the apparatus, etc.And capable of dessulfurizar highly a fraction of diesel economically.
