May I ask about the current situation regarding diesel blending? There are many quality requirements for national standard diesel at present; what are the blending strategies used by refineries these days? Is it basically made by blending hydrogenated diesel? What other additives are needed for the blended diesel? Cetane number improvement, antifreeze agents, stabilizers – are these still needed?
It is necessary to add them. There might be a misconception here: many people think that diesel and gasoline with additives are of lower quality, but this is not the case. You can consider additives as just another component, with their addition levels being in the PPM range. For example, anti-wear agents are needed because the higher the degree of hydrogenation, the larger the wear marks on diesel, and thus anti-wear agents are required to improve lubricity. According to the current national standards for diesel, certain additives are mandatory. For detailed discussion, add +V18253330777
The improvement of certain manufacturing techniques has also replaced the need for many additives; it cannot be generalized
