Can excessive reaction depth in diesel hydrorefining lead to unacceptable color?
The color of hydrogenated reformulated diesel is related to the properties of the crude oil, the processing techniques, and the degree of refining; it cannot be generalized.
The higher the reaction depth, the more impurities are removed through the refining process, resulting in better diesel quality; so how can the color value be unsatisfactory? The conditions for diesel cracking reactions are more stringent.
Could an excessively high temperature in the reaction bed cause diesel cracking? Recently, the proportion of coker gasoline in the feed oil used in the plant has increased, which has led to a rise in temperature; however, the color of the diesel has become darker, while there have been no significant changes in the properties of the other feed oils
If there is a cracking agent, excessive cracking will indeed occur
