Description

Dme mixing automotive fuel and preparation method thereof
Technical field
The invention belongs to dme product technical field, particularly relating to a kind of take dme as the mixing automotive fuel of main component.
Background technology
Dme, also known as methyl ether, is called for short DME.Dme is a kind of colourless gas or compressed liquid at normal temperatures and pressures, has slight ether fragrance.Relative density (20 DEG C) 0.666, fusing point-141.5 DEG C, boiling point-24.9 DEG C, under room temperature, vapour pressure is about 0.5MPa, similar to oil liquefied gas (LPG).Inflammable, when burning, flame is slightly bright, and the combustion heat (gaseous state) is 1455kJ/mol.Under normal temperature, DME has inertia, not easily autoxidation, corrosion-free, non-carcinogenesis.
Dme, as a kind of basic chemical raw materials, due to its good easy compression, condensation, vaporizing property, makes dme in the chemical industry such as pharmacy, fuel, agricultural chemicals, have the purposes of many uniquenesses.As domestic fuel gas, its accumulating, combustion safety, the performance index such as premix gas calorific value and theoretical combustion temperature are all better than oil liquefied gas, can be used as the peak regulation gas of Town Gas, liquefied gas mixed gas.Also be the ideal fuels of diesel motor, compared with methanol fuel automobile, there is not cold-starting automobile problem.
Current most of dme manufacturing enterprise has all directly burnt dme as fuel, and supply exceed demand due to dme output, and product is single, the inefficiencies of related production enterprise, even heavy losses.
And directly also there is very large technical problem as fuel use in dme, wherein, dme and liquefied petroleum gas medium have a great difference, dme is all that methanol dehydration is made mostly, if produce formaldehyde during dme " air-fuel ratio " unreasonable burning, formaldehyde is that drugs carcinogens has injured user greatly, polluted environment.
Can how better utilised dme fuel thus the problem reducing environmental pollution has become the new focus that current industry can be explored as an alternative.
Summary of the invention
To be solved by this invention is for the problem in background technology, and providing a kind of take dme as the mixing automotive fuel of main component.
In order to solve the problem by the following technical solutions: a kind of dme mixing automotive fuel, is mixed by the material of following weight part: 80 ~ 90 parts of dme, 5 ~ 10 parts of methylals, 1 ~ 5 part of isopropylcarbinol, 1 ~ 5 part of polymethoxy dimethyl ether.
Preferably, mixed by the material of following weight part: 90 parts of dme, 5 parts of methylals, 2.5 parts of isopropylcarbinols, 2.5 parts of polymethoxy dimethyl ethers.
Another kind of scheme, is mixed by the material of following weight part: 80 parts of dme, 10 parts of methylals, 1 part of isopropylcarbinol, 5 parts of polymethoxy dimethyl ethers.
The third scheme, is mixed by the material of following weight part: 85 parts of dme, 7 parts of methylals, 5 parts of isopropylcarbinols, 1 part of polymethoxy dimethyl ether.
4th kind of scheme, is mixed by the material of following weight part: 90 parts of dme, 5 parts of methylals, 3 parts of isopropylcarbinols, 3 parts of polymethoxy dimethyl ethers.
In above four kinds of schemes, wherein, dimethyl ether purity be more than 99.9%, methylal purity more than 95%, isopropylcarbinol purity more than 99%, polymethoxy dimethyl ether purity more than 99%.
The preparation method of dme mixing automotive fuel is as follows: getting dme is that base-material adds in dimethyl ether storage tank, then adds methylal, isopropylcarbinol and polymethoxy dimethyl ether with pump successively, leaves standstill more than 4 hours, then carry out filling use after mixing.
A kind of detailed preparation method is specifically provided: get 900 kilograms of purity be 99.9% dme add in dimethyl ether storage tank; Then 50 kilograms of methylals, 25 kilograms of isopropylcarbinols, 25 kilograms of poly-methyl dimethoxy ethers are entered in dimethyl ether storage tank by infusion successively, can filling use after mixing static 4 hours.
The dme mixing automotive fuel produced in the present invention, by adding methylal for improving fuel cold starting performance; Add appropriate isopropylcarbinol for fuel dispersants; Also add polymethoxy dimethyl ether, for improving fuel value simultaneously; Thus to can be good at solving in background technology dme as the weak point of fuel.Its production cost is low, good in economic efficiency, also meets the requirement of the substituted type fuel economy environmental protection that China advocates, has this more wide market outlook.
