Embodiment 1

[0176] A comparison of Examples 1 and 2 shows that using the same catalyst volume (54.6m 3 ), the application of the invention makes it possible to operate the first reactor at 357°C instead of 362°C in the case of Example 1. This 5°C difference has a considerable energy saving effect, and it would be even better if some of the heat was recovered from the effluent from the first reactor. Also, because the conditions are less severe, the operating period is found to be extended. In this case, an extension of at least 5 months to the operating period can be expected. Furthermore, the second reactor in Example 2 is characterized by a very long operating cycle due to the relatively low operating temperature, which is nevertheless sufficient to obtain 10 ppm diesel fuel at the outlet.

[0177] A comparison of Examples 1 and 3 shows that at the same average reaction temperature in the first reactor, the catalyst volume required to obtain 10 ppm diesel fuel at the outlet is lower w...

Abstract

The invention relates to a method for the catalytic hydro-processing of a petroleum feedstock of the gas oil type and of a biological feedstock containing vegetal oils and/or animal fats, in a catalytic fixed-bed hydro-processing unit, said method being characterised in that the petroleum feedstock is introduced into the reactor upstream from the biological feedstock. The invention also relates to a catalytic hydro-processing unit for implementing said method, and to a corresponding hydro-refining unit.

Description

technical field [0001] The invention relates to a method for hydrotreating diesel engine fuel raw materials, a hydrotreating device for realizing the method, and a corresponding hydrorefining device. Background technique [0002] Due to increasingly stringent diesel pollution control standards, diesel fuel specifications have changed over the last two decades and new restrictions have emerged, resulting in improvements in diesel fuel blend formulations. [0003] Since January 2005, the specifications of diesel engine fuel are as follows: (European standard EN590): [0004] Density (15°C): 820-845kg / m 3 [0005] T95% (distillation temperature at which 95% of diesel fuel is distilled): 360°C (maximum) [0006] Sulfur content: 50mg / kg (maximum) [0007] Engine cetane number: 51 (minimum) [0008] Calculated cetane index (ASTM D4737): 46 (minimum) [0009] Cloud point: <-5°C (in winter) [0010] <+5°C (in summer). [0011] Therefore, the desired base oils are light...
