Abstract
The general composite liquefied dimethyl ether gas consists of dimethyl ether 35-70 wt%, liquefied petroleum gas 30-50 wt% and additive 10-20 wt%. The outstanding advantage of the present invention is that the general composite fuel is compatible with available liquefied petroleum gas, that is, it may be stored in available steel cylinder for liquefied petroleum gas and burnt in available oven for liquefied petroleum gas.
Description
One, technical field
The invention belongs to the carbonaceous fuel technical field, be specifically related to a kind of compound fuel of mainly forming by dme.
Two, background technology
At present, China as domestic fuel mainly be oil liquefied gas, and the demand of oil liquefied gas is with increasing.Along with the increase of the demand of oil liquefied gas, the China's oil import volume is also increasing.Show that according to relevant material in 2000,7,000 ten thousand tons of China's net importation crude oil, 2,000,000 tons of processed oils near 30% of total demand, beat alarm bell for the energy security problem of China.Dme gas is a kind of colourless, nontoxic, eco-friendly compound, is to be that raw material makes methyl alcohol with the coal, and methanol dehydration obtains dme.Rich coal resources in China, petroleum resources reduce day by day at present, make full use of the coal resources of China, and exploitation dme clean fuel is fit to the energy structure of China very much, also is the general orientation of China's energy source optimization utilization and the energy and environmental technology development.
Chinese patent once disclosed a kind of " ether-hydrocarbon liquid compound fuel " (ZL99115710.9, Granted publication day: on May 15th, 2002), it is characterized in that it is made up of dme, pentane and oil liquefied gas, the contained per-cent of each component is: dme 20-40%, pentane 50-70%, oil liquefied gas 0-20%, advantages such as it has the calorific value height, it is little to pollute, safety and sanitation, low price, but the fuel of being prepared needs special-purpose assorted kitchen range to burn, this is unfavorable for applying, so the existing market difficulty is seen this class A fuel A.
Three, summary of the invention
The object of the present invention is to provide a kind of compound liquid dimethyl ether for hearth and tank, the kitchen range jar of the oil liquefied gas that generally uses on kitchen range jar that the fuel of being prepared is required and the present market is general.
For achieving the above object, the solution that the present invention takes is: a kind of compound liquid dimethyl ether for hearth and tank, it is made up of dme, oil liquefied gas and additive, and the contained weight percent of each component is: dme 35-70%, oil liquefied gas 30-50%, additive 10-20%.The component of additive is that the master adds ferrocene and acetone with the Skellysolve A, and its weight percent is: Skellysolve A 90-95%, ferrocene 0-5%, acetone 0-5%.
Dme (DME) is more and more paid attention to by people as novel clean fuel.Dme is colourless, odorless gas under normal temperature, normal pressure, owing to himself contain oxygen, component is single, therefore have good burning performance thermo-efficiency height, noresidue in the combustion processes, no black smoke, become universally acknowledged clear energy sources, as the ideal substitute of liquefied petroleum gas (LPG) and diesel oil.Biggest advantage of the present invention is: the fuel of being prepared need not special-purpose assorted kitchen range and burns, but burns with the oil liquefied gas standard cooking stove that generally uses in the market and steel cylinder stores, and this just helps applying widely.Applying of it will produce huge economic benefit and social benefit.
Four, embodiment
Embodiment one:
Dme 60%, oil liquefied gas 30%, additive 10%.
Embodiment two:
Dme 50%, oil liquefied gas 30%, additive 20%.
Embodiment three:
Dme 35%, oil liquefied gas 50%, additive 15%.
The present invention is mainly according to the physico-chemical property of dme, and formulated fuel makes it to have that cost is low, pollution is little, toxicity is low, safety, health, can replace oil liquefied gas as domestic fuel fully.The physical properties of dme is similar to oil liquefied gas, its boiling point-25.1 ℃, fluid density 0.67gcm
-3(20 ℃), liquid viscosity 0.12～0.15kgms
-1, saturated vapor pressure 0.6MPa (25 ℃), vaporization heat 467kJkg
-1, gas density 1.59 (to air), theoretical air than 9.0 (kg: kg), maximum combustion speed 50cms
-1, explosive range 3.4～17%, 235 ℃ of flashing temperatures, cetane value 55～60, lower heating value 59.3MJ (Nm
3)
-1, lower calorific value 28.8MJkg
-1, therefore alternative oil liquefied gas, diesel motor fuel also can be used as fuel such as fuel cell, fuel-burning power plant, produce low-carbon alkene by decomposition, and alternative cfc is made aerosol, refrigeration agent and whipping agent.The purpose of adding additive is combustion-supporting, is flame height and the fuel stability in order to improve fuel.The same specification kitchen range combustion conditions contrast of the fuel that the present invention prepared and liquefied dimethyl ether gas and oil liquefied gas is as following table.
The same specification kitchen range of different fuel combustion conditions
| Fuel band | Liquefied dimethyl ether gas | Oil liquefied gas | The embodiment of the invention one |
| Prescription | Pure | Pure | Dme 60%, oil liquefied gas 30%, additive 10%. |
| Press in the steel cylinder (MPa) | 0.5 | 0.4 | 0.45 |
| Combustion conditions | The flame height deficiency | The flame height is with flourishing | Good |
| The boiled 1Kg unboiled water time (min) | 6.6 | 4.4 | 4.2 |
Claims (2)
1, a kind of compound liquid dimethyl ether for hearth and tank is characterized in that: it is made up of dme, oil liquefied gas and additive, and the contained weight percent of each component is: dme 35-70%, oil liquefied gas 30-50%, additive 10-20%.
2, a kind of compound liquid dimethyl ether for hearth and tank according to claim 1 is characterized in that: the component of described additive is that the master adds ferrocene and acetone with the Skellysolve A, and its weight percent is: Skellysolve A 90-95%, ferrocene 0-5%, acetone 0-5%.
