Problems solved by technology

But these methods are time-consuming, energy-consuming, the effect is not very obvious, and increase the cost
At present, the octane number of gasoline leaving the refinery is increased by using additives, such as adding tetraethyl lead and methyl tert-butyl ether (MTBE) to gasoline, but these additives have the following problems: tetraethyl lead has severe It is poisonous and has been banned. Methyl tert-butyl ether (MTBE) pollutes groundwater and has been banned in developed countries. There are also clear restrictions on the content of metal manganese and iron in gasoline

Abstract

The invention relates to a high-environmental-protection clean gasoline additive and a preparation method thereof. The gasoline additive is prepared from the following components in percentage by weight: 89-95 percent of clean antiknock, 3-5 percent of carboxylic aromatic ester and 2-6 percent of arylamine which sum up to 100 percent. The preparation method of the high-environmental-protection clean gasoline additive comprises the following steps of: respectively taking one of methylal or acetal, C1-C10 saturated alcohol and a catalyst according to a weight ratio of 0.55-0.75:1:0.05; carrying out a reflux reaction at 60+ / -5 DEG C for 5-6 h; rectifying and recycling the liquid at 60-90 DEG C to prepare a clean antiknock; adding the carboxylic aromatic ester and the arylamine to the clean antiknock, slowly stirring, evenly mixing, filtering and collecting the filtrate to obtain the high-environmental-protection clean gasoline additive. The gasoline additive of the invention can improve the octane value of the gasoline and decrease the production cost without containing banned substances.

Description

technical field [0001] The invention belongs to the field of energy technology, and relates to an additive capable of increasing gasoline octane number, enhancing gasoline antiknock performance, and reducing harmful substances in tail gas, in particular to a highly environmentally friendly and clean gasoline additive, and the invention also relates to the preparation of the gasoline additive method. Background technique [0002] As a commonly used fuel, gasoline is widely used in various vehicles to provide power for it. However, gasoline produces a large amount of harmful substances during the combustion process, which causes serious pollution to the atmospheric environment. In order to reduce the pollution caused by the use of fuel , People have strictly controlled the exhaust emissions of vehicle fuels, and required unleaded, low-olefin, low-emission, and high-standard gasoline. Many countries have spent a lot of manpower and financial resources on low-pollution and low-...
