Description

A kind of alcohol ether base transferable fuel

Technical field

The present invention relates to a kind of domestic fuel, the novel alcohol ether base transferable fuel of particularly a kind of alternative Sweet natural gas and liquefied gas.

Background technology

Along with China's living standards of the people must improve, liquefied gas (or coal gas) user of China big and medium-sized cities surpasses 70% at present, and vast rural area also has increasing people using bottled gas, and the consumption market is huge.Relevant statistical information shows: the consumption of China's liquefied gas in 2007 surpasses 3,000 ten thousand tons, annual nearly ten million ton of the diesel oil that consumes of simultaneously national catering trade.It is estimated: the counties and cities of one 500,000 population, about 1.8 ten thousand tons of year consumption liquefied gas, the annual diesel oil that consumes of catering trade reaches more than 2000 tons.

Along with to the raising of environmental requirement and the aggravation of petroleum-based energy crisis, fuel is in short supply, and price day is high one day, and therefore exploitation renewable substitute energy cheap, cleaning is extremely urgent.Methyl alcohol is as a kind of green fuel that obtains by starch-containing and cellulosic biomass ferment method and coal transformation technology, and advantages such as having wide material sources, be convenient to accumulating, be cheap is subjected to people and greatly notes.But because there are shortcomings such as calorific value is lower, incomplete combustion in methyl alcohol, its use is subjected to and must limits.As power fuel, people strengthen emphatically making it be converted into more incendive hydrogen-rich gas to the engine flexibility research of methanol fuel and by methods such as catalytic pyrolysis steam reformation and partial oxidations in recent years for this reason.And as domestic fuel, people then pay attention to when guaranteeing its basic combustionproperty, in the optimization proportion design research of minimizing cost.And it is very few for the research of calorific value that improves methanol fuel by formulating of recipe and catalytic conversion and the discharging of further minimizing Litter.

Summary of the invention

The objective of the invention is to provides a kind of clean environment firendly, calorific value height and price the low alcohol ether base transferable fuel based on methyl alcohol for overcoming the deficiencies in the prior art.

For achieving the above object, the invention discloses a kind of alcohol ether base transferable fuel, it is characterized in that its component and mass percentage content are: alcohol ether class A fuel A mixed solution 65～70, water 25～39, organic catalyst 0.015～0.04, combustion improver 1～5, inhibiter 0.02～0.05, wherein alcohol ether class A fuel A mixed solution is a methyl alcohol, butanols and acetone, the mixture of ethers, ethers is a dme, isopropyl ether, any two kinds mixture in the methyl tertiary butyl ether, organic catalyst is triethyl aluminum or ferrocene, and combustion improver is the mixture of hydrogen peroxide and potassium permanganate, and described inhibiter is a trolamine.

Compared with prior art, the invention has the beneficial effects as follows: this alcohol ether base transferable fuel is based on alcohols, have wide material sources, be convenient to accumulating, advantage such as cheap, join with acetone, dme, isopropyl ether lower boiling industrial chemicals, can improve the low temperature ignition of alcohols.Add hydrogen peroxide, potassium permanganate again as combustion improver, to provide burning required oxygen.Particularly add organic catalyst triethyl aluminum and ferrocene in fuel, they can provide the Al/Fe catalyzer that impels methyl alcohol burning changing into hydrogen and carbon monoxide in the presence of water vapour.

CH ₃OH→CO+2H ₂

Because the combustion of hydrogen value is 142,351kJ/kg is 3 times of gasoline calorific value, has good burning performance, and lights soon, and flammable range is widely arranged during with air mixed, and combustionvelocity is fast, so can improve the fuel value of methyl alcohol greatly, promotes the perfect combustion of methyl alcohol.And butanols and trolamine can be adjusted the viscosity of fuel and burner is played the inhibition protection effect when increasing combustionproperty respectively; therefore this fuel has the calorific value height, combustionproperty is good; lighting-up rate is fast, the characteristics of safety, environmental protection, can instead of natural gas and liquefied gas.
