Description

Ethanol petrol and compound method

Technical field

The present invention relates to a kind of ethanol petrol and compound method.

Background technology

The world petroleum resource exhaustion, and the consumption of China's oil still increases sharply with the speed in year 13%.China's hydrocarbon resources relative shortage just became net import of oil state from 1993, and petroleum demand increased progressively 7% every year in nearly 5 years, and actively seeking new automobile-used substitute energy becomes one of main path of alleviating contradiction between oil supply and demand.Ethanol is renewable resources as the sun power material that is transformed by grain.The grain-production district of China can provide abundant raw material sources for promoting ethanol petrol.Along with developing of automobile industry, the variation of following automobile fuel is a megatrend, and ethanol petrol will present its potential business opportunity.The ethanol petrol that carry out in our times various countries and domestic each province and city, what face mainly is that cost is too high, octane value is not high, calorific value is lower, oil consumption is higher, low temperature driveability and drive problems such as acceleration characteristics is relatively poor.

Summary of the invention

The present invention aims to provide a kind of E 33 modification ethanol petrol fuel and concocting methods, and purpose is to provide a kind of need not to reequip available engine and oiler structure, by improving additive and concocting method, produces a kind of ethanol petrol fuel of direct use.Adopt part methyl alcohol to replace ethanol simultaneously, and methanol prices far below ethanol, so also solved the problem of the ethanol selling at exorbitant prices that ethanol petrol faced.

Technical scheme of the present invention: ethanol petrol each component weight percent of the present invention is: ethanol: 10%-25%, gasoline: 67%-85%, additive: 2%-3%, methyl alcohol: 3%-5%.
