Embodiment Construction

[0021] In order to better illustrate the present invention, give an example as follows:

[0022] 1. Carbon five modification

[0023] Add 60kg of maleic anhydride in the reaction kettle, heat and melt, add mixed carbon five to it, after the reaction is exothermic, add 2g of catalyst zinc chloride, keep the reaction temperature at 80~90°C, and react for 2-3 hours, solid-liquid Separating and getting the liquid product is the modified carbon five used in the present invention.

Abstract

The invention provides application of modified carbon-5 in a gasoline additive, which belongs to the technical field of recycling gasoline side products and particularly discloses a method for treating light hydrocarbons taking carbon-5 as a main composition and application of the treated carbon-5 in the gasoline additive. When the modified carbon-5 is used, 50 to 80 percent of the additive according to the weight percentage is added in gasoline to produce composite gasoline, thereby not only partially replacing the gasoline fuel with tension in supply, but also improving the performance of the gasoline, ensuring that the gasoline is fully burnt and reducing the coking and carbon deposition in an engine and the emission of harmful matters; moreover, according to the inspection by the National Ethanol Gasoline Quality Surveillance Inspection Center, the composite gasoline meets the national standard.

Description

technical field [0001] The invention belongs to the technical field of petroleum by-product reuse, and specifically relates to the application of carbon five in gasoline additives. Background technique [0002] Liquid raw materials such as naphtha and light oil account for more than 90% of my country's ethylene raw materials, and the content of C5 fractions after cracking is relatively large, up to more than 20% of ethylene production. In recent years, with the continuous expansion of my country's ethylene production scale and the increase of heavy components in my country's ethylene raw materials, the by-product C5 fraction of ethylene plants also increases accordingly, and the yield of C5 is increasing. The comprehensive utilization of my country's C5 more urgent. According to statistics, at present, 90% of the by-product C5 fraction of ethylene cracking in my country is used as fuel for cracking furnaces and steam boilers, 3% is used for the production of petroleum resin,...
