Abstract

The present invention is one process of hydrofining coked full fraction oil. Based on available process of hydrofining coked full fraction oil, new hydrogen of the system is used in further refining of diesel oil, so that diesel oil is refined under ideal thermodynamic and dynamic conditions. This results in high product quality, flexible, economic and practical technological process, less investment increment, fully utilization of heat energy and low operation cost. The present invention is suitable for reforming and constructing coked full fraction oil hydrofining apapratus.

Description

1. Technical field [0001] The invention relates to a method for hydrofinishing coking whole distillate oil, in particular to a method for hydrofinishing coking whole distillate oil that can directly obtain Class II diesel standard diesel oil. 2. Background technology [0002] With the continuous development of the national economy, the market demand for petroleum products continues to increase, especially the demand for clean diesel oil increases faster. Correspondingly, with the continuous exploitation of crude oil, crude oil is gradually becoming heavier and inferior, and the quality of diesel directly obtained from secondary processing is even worse. Coking is a commonly used means of lightening residual oil. Its advantages are low investment, wide sources of raw materials, and raw materials with poor properties can also be processed. The disadvantage of coking is that the product contains impurities in the raw material and needs further processing. Coker whole distilla...
