Abstract
The invention relates to a method for preparing alcohol-based biofuel, for solving the defects and boundednesses of low aeration efficiency of the fuel, and over-high combustion temperature caused by low combustion efficiency in the technical field of the traditional novel fuel. According to the technical solution, the method comprises the following steps of: a, putting methanol to a reaction container device; adding isobutanol in proportion, so that the biofuel changes; and b, agitating the biofuel material in the reaction container device for 50 minutes, and then adding n-butyl alcohol, isooctane, MTBE (methyl tert-butyl ether) and ferrocene, agitating and reacting for 30 minutes, so that the biofuel change achieves the national fuel efficiency standards for cars. The method has the characteristics of high octane value, large latent heat of vaporization, low calorific value, good anti-detonating quality and the like; the alcohol-based biofuel contains oxygen; the oxygen combustion rate in combustion of an engine can be improved; the air inlet temperature is reduced; the aeration efficiency is improved; the highest combustion temperature is reduced; and the NOx discharge of the engine is also reduced. Hardly soot is discharged; and the method has cleanability.
Description
[technical field]
The present invention relates to a kind of method for preparing the alcohol radical bio-fuel-oil.
[background technology]
Modern market is promoted a lot of novel fuels, the technology that these fuel oils use is generally just carried out the physics fusion with 15%～25% methyl alcohol and gasoline product, but such Modern New fuel oil, efficiency of combustion is low, cause the fuel oil charging efficiency lower, maximum combustion temperature is too high, and its shortcomings and limitations are arranged, and is difficult in a short time large-scale promotion and application.Therefore, reduce inlet air temperature, improve charging efficiency, reduce maximum combustion temperature, reduce the NOx quantity discharged of engine, improving simultaneously alcohol radical bio-fuel-oil efficient is present problem demanding prompt solution.
[summary of the invention]
Low in order to solve the efficiency of combustion that has the existence of novel fuel technical field now, cause the fuel oil charging efficiency lower, the shortcomings and limitations that maximum combustion temperature is too high the invention provides a kind of method for preparing the alcohol radical bio-fuel-oil.This alcohol radical bio-fuel-oil is take methyl alcohol as the principal reaction medium, add isopropylcarbinol, propyl carbinol, octane-iso, MTBE (methyl tertiary butyl ether, molecular formula C4H9OCH3, it is a kind of high octane gasoline component, its basic octane value RON:118, MON:100 is good gasoline high-octane rating additive and octane promoter.), ferrocene etc. becomes the bio-fuel-oil base to reach national vehicle fuel standard, as the fuel of motor car engine.
The technical scheme that alcohol radical bio-fuel-oil of the present invention adopts is: prepare the method for alcohol radical bio-fuel-oil, it is characterized in that may further comprise the steps:
A, in reaction vessel device, put into methyl alcohol, add isopropylcarbinol by proportioning again, the bio-fuel-oil base is become.
B, the bio-fuel-oil based raw material stirring reaction in reaction vessel device add propyl carbinol, octane-iso, MTBE, ferrocene after 50 minutes again, and stirring reaction 30 minutes makes the bio-fuel-oil base become the national vehicle fuel standard that reaches.
Each component preferred weight of alcohol radical bio-fuel-oil raw material of the present invention matches well and is:
Methyl alcohol 1000L, isopropylcarbinol 300ml, propyl carbinol 100ml, octane-iso 500ml, MTBE 800ml, ferrocene 0.5ml.
The invention has the beneficial effects as follows: the present invention selects methyl alcohol as the principal reaction medium, has lower critical temperature, reaction conditions is low, be equipped with isopropylcarbinol, propyl carbinol, octane-iso, MTBE, the reaction of ferrocene scientific allocation, make the alcohol radical bio-fuel-oil have the characteristics such as octane value is high, the latent heat of vaporization large, calorific value is lower, as automobile fuel, the alcohol radical bio-fuel-oil itself contains oxygen, in engine combustion, can improve oxygen combustion rate, almost discharge without soot.In addition, the latent heat of vaporization is high, can reduce inlet air temperature, improves charging efficiency, reduces maximum combustion temperature, reduces the NOx quantity discharged of engine.Therefore, Aalcohols fuel is used in the suitable area at home, has more spatter property, and anti-knocking property are good.
[embodiment]
The preparation technology of alcohol radical bio-fuel-oil of the present invention is:
By above-mentioned methyl alcohol 1000L, isopropylcarbinol 300ml, propyl carbinol 100ml, the preferred weight of octane-iso 500ml, MTBE800ml, ferrocene 0.5ml matches well, first 1000L methyl alcohol is put into reaction vessel device, in methyl alcohol, add again the 300ml isopropylcarbinol, making it produce reactive group becomes, then the bio-fuel-oil based raw material stirring reaction in reaction vessel device is after 50 minutes, add again propyl carbinol, octane-iso, MTBE, ferrocene, stirring reaction 30 minutes, fully stirring reaction makes the change of bio-fuel-oil base reach national vehicle fuel standard, namely becomes alcohol radical bio-fuel-oil finished product.
Alcohol radical bio-fuel-oil finished product of the present invention has the characteristics such as octane value is high, the latent heat of vaporization large, calorific value is lower, anti-knocking property are good, the alcohol radical bio-fuel-oil itself contains oxygen, in engine combustion, can improve oxygen combustion rate, reduce inlet air temperature, improve charging efficiency, reduce maximum combustion temperature, reduce the NOx quantity discharged of engine, almost without the soot discharging, have more spatter property.
