How can Euro 4 standards be achieved after catalytic hydrogenation of a mixture of diesel and coker diesel? . . .

Reaching Euro 4 standards for diesel is quite difficult. . . One is aromatic hydrocarbons, and the other is sulfur content. . . High-pressure hydrogenation reforming may be required. . . :lol

The Euro 4 standard is quite stringent, requiring a sulfur content of less than 150 ppm. The catalyzed diesel we produce can achieve a sulfur content of less than 190 ppm after hydrorefining; to reach the 150 ppm threshold, it is necessary to further mix it in certain proportions with hydrotreated diesel

The Euro 4 standard requires a sulfur content of no more than 50 PPm, and this requirement can be met by using highly selective catalysts along with appropriate operating conditions.
