Problems solved by technology

[0003] In the past, in the process of diesel production, various refineries needed to add pour point depressants, cetane accelerators, oxidation stabilizers, anti-wear lubricants, corrosion inhibitors and other additives to reconcile refined oil to solve the problems of quality and cost , because various additives are provided by different manufacturers in their own independent dosage forms, there are the following problems: (1) The number of additions is too many and the operation is complicated, resulting in increased production and testing costs; (2) The mutual compatibility between the additive products of different manufacturers It cannot be guaranteed, and the interaction between them is uncontrollable, resulting in unstable quality of diesel oil, especially the unsatisfactory pour point depressing effect and oxidation stability performance, low power, and poor cleaning and environmental protection performance; (3) The cost increases, causing enterprises to profit decline

Description

technical field [0001] The invention belongs to the technical field of preparation of chemical products, and relates to a blending component of diesel oil, in particular to a blending component used for blending the properties of finished oil in the process of producing high-power clean diesel oil. The product can be widely used in waxy catalytic cracking diesel oil, It is suitable for the production modulation of straight-run diesel oil, various blended diesel oil and heavy oil catalytic cracking diesel oil, and also suitable for the production modulation of a small number of unstable hydrogenated diesel oil. Background technique [0002] At present, with the continuous exploitation of major domestic oil fields for many years, the content of heavy oil in crude oil is getting higher and higher. In addition, some companies have removed aviation fuel during the refining process, resulting in higher content of heavy components, resulting in a decline in the quality of refined oi...
