Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below in conjunction with examples.

[0022] Generally, according to the liquefaction process of coal-based liquefied fuel oil, it can be divided into two types: Diesel of Direct Coal Liquefaction (hereinafter referred to as DDCL) and coal indirect liquefied diesel (Diesel of Indirect Coal Liquefaction, hereinafter referred to as DICL). With the mandatory implementation of national III, IV, and V diesel standards, the production of vehicle diesel that meets the new standards is also fully implemented. The new standards put forward stricter requirements for sulfur content. Compared with petroleum-based diesel, DICL has low aromatics content and almost no sulfur and nitrogen content. The cetane number of diesel oil can reach more than 70-80. Among them, low aro...

Abstract

The invention discloses a diesel oil blend component and a production method thereof. The diesel oil blend component consists of direct coal liquefaction diesel oil, indirect coal liquefaction diesel oil and lubricant additive. Only the direct coal liquefaction diesel oil (DDCL) and indirect coal liquefaction diesel oil (DICL) are blended as raw materials, and the lubricant additive is added to the blended fuel, so as to obtain the diesel oil blend component with indicators such as density, condensation point, cold filter plugging point, viscosity, cetane number and the like meeting requirements; particularly, the DDCL and DICL are optimized and blended to produce a clean diesel oil product consistent with new national IV or Beijing V automotive diesel oil standard. The process disclosed by the invention is low in cost, simple in process and easy to operate.

Description

technical field [0001] The invention relates to the technical field of advanced processing of coal liquefied oil, in particular to a diesel blending component and a production method thereof. Background technique [0002] The rapid development of my country's national economy has continued to demand strong energy. Since my country became a net oil importer in 1993, the gap between oil supply and demand has expanded year by year, and the dependence on foreign crude oil has increased year by year. In 2006, the foreign dependence of crude oil was 43%, and in 2007 It is expected to exceed 46% in 2020 and reach 60% in 2020. Fluctuations and changes in the international oil market will directly affect the security and stability of our country's economy and politics. Solving the supply and demand problem of liquid fuels by synthesizing liquid fuels through non-petroleum routes not only meets the national energy strategic security requirements, but also plays an important role in pr...
