Problems solved by technology

Therefore, the content of manganese metal is strictly limited in gasoline National III, National IV and National V standards, which greatly restricts the addition of MMT in gasoline.
[0006] Due to the particulate matter pollution produced by metal antiknock agents and the damage to the three-way catalytic converter, the research on it is at a relatively stagnant stage
The emphasis of research on antiknock agents in various countries has been placed on non-metallic gasoline antiknock agents. People first began to use non-metallic MTBE in large quantities to blend gasoline, but the amount of MTBE added is relatively large (10-15%),

Example Embodiment

[0026] Example 1

[0027] Into a 250ml four-necked flask, 80g of ester compounds (mixture of methyl acetate and dimethyl malonate, mass ratio 2:1), 20g of oxygen-containing aromatic amine compounds (p-ethoxyaniline, 4-methyl Oxy-N-methylaniline mixture, mass ratio 1:1) and 0.1g 2,6-di-tert-butyl-p-cresol, mix and stir uniformly to obtain a light yellow transparent liquid, which is a non-metallic gasoline antiknock agent;

[0028] Add the obtained new non-metal gasoline antiknock agent to 88# catalytic cracking gasoline according to different quality, and measure the increase value of gasoline octane number. The measurement results are shown in the following table:

Abstract

The invention relates to the technical field of petrochemical engineering, in particular to a novel nonmetallic gasoline antiknock. The nonmetallic gasoline antiknock consists of the following components in parts by weight; 20 to 50 parts of an oxygen-containing arylamine compound, 50 to 80 parts of an ester compound and 0.01 to 1 part of a phenolic compound, and does not contain any metallic component. An experimental result of the antiknock shows that the octane value of gasoline can be increased by 1.0 to 8.0 units after 0.5 to 3 weight percent of the novel nonmetallic gasoline antiknock is added into gasoline and high antiknock performance is achieved; in addition, the novel nonmetallic gasoline antiknock has the advantages of low raw material cost, performance indexes consistent with a national V gasoline standard, no bad influence on a spark plug engine, capability of effectively reducing environmental hazards, and the like, and has high application value and good economic benefits.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, and relates to a novel non-metallic gasoline antiknock agent capable of significantly increasing the octane number of gasoline. Background technique [0002] The development of the automobile industry, the urgency of energy conservation and environmental protection, promote the replacement of gasoline products. In order to meet the new gasoline specifications, an important problem facing my country's oil refineries is how to increase the octane number of gasoline. There are the following ways to increase the octane number of gasoline: (1) process method, that is, to improve oil refining technology, such as catalytic cracking, catalytic reforming, alkylation, isomerization, etc.; (2) blending method, that is, to transfer high-octane Alkane number components, such as industrial isooctane, methyl tert-butyl ether (MTBE), alcohols, etc.; (3) Additive method, that is, adding gasoline a...
