Description
Technical field
The present invention relates to derived energy chemical technical field, particularly a kind of fuel dope and apply its industrial or civilian low-carbon (LC) clean fuel.
Background technology
The world today faces two large global problems, and one is petroleum-based energy crisis, and two is environmental pollutions.The explored reserves of Global Oil are 1,421 hundred million tons, by nearly 10 annual year the amount of adopting 35.6 hundred million tons, at most also can maintain 40 years.China's oil reserves are limited, net import of oil state has been become from 1993, annual China imported crude oil 2.39 hundred million tons in 2010, it is second-biggest-in-the-world oil importers, be only second to the U.S., the external dependence degree of the energy, up to 55%, has entered energy Warning years, the aggravation of this situation will seriously restrict China's expanding economy, even can have influence on the national defense safety of China.Within 2011, China's vehicle guaranteeding organic quantity is 20754.6 ten thousand, fuel is done with refined oil, tail gas discharging pollutant reaches 4607.9 ten thousand tons, automobile pollution has become China's air-polluting important sources, be the major reason causing gray haze, photochemical pollution, the urgency of Motor Vehicle Pollution Prevention highlights day by day.In February, 2012, State Council approved is issued " ambient air quality " of new revision, and propose higher requirement to fine particle in air (PM2.5) control, Motor Vehicle Pollution Prevention becomes essential domain.Therefore, develop the imbalance between supply and demand that alternative clean energy is not only conducive to alleviating China's oil, reduce dependence on foreign countries for oil, effectively can also administer atmospheric pollution.
Dme (English full name is dimethyl ether, referred to as DME) comes into one's own day by day as the clean fuel changed into from coal-based feedstocks, becomes the carbon-Chemicals of the superior performance that recent domestic is competitively developed.As liquefied petroleum gas (LPG), (English full name is Liquefied Petroleum Gas, be called for short LPG) and the alternative fuel of petroleum-type, dme has the chemical similar with the physical properties of LPG, and enriching in view of coal in China reserves, make the source more horn of plenty of dme, more optimizedly DEM itself is containing oxygen, only has C-O bonding c h bond, therefore DME sufficient combustion in molecular structure, not carbon distribution, pollutant discharge amount is low, does not stay raffinate in storage tank, can cheaply and in large quantities produce.The same with methane, one of the energy becoming 21 century that is supposed to, has boundless prospect.

By the end of the year 2010, China will have dme manufacturing enterprise 60, and production capacity adds up to 1,484 ten thousand tons, and China has become the maximum dme producing country in the whole world.At present, the exploitation of China to dme are paid much attention to.Dme is the New-type fuel that country promotes, in August, 2007, the Ministry of Construction promulgated " city gas dme " industry standard, the Ministry of Finance and the State Tax Administration have issued " using the notice of tax rate problem about dme value added tax " in June, 2008, announce from 1 day July in 2008, dme VAT rate is adjusted to 13% by 17% time.To help the popularization of dme as domestic fuel, alleviate the immense pressure of China's oil liquefied gas supply, calculate with the market rate of exchange of current liquefied petroleum gas (LPG) and dme, dme is a kind of economical and practical liquefied petroleum gas (LPG) alternative fuel.National Development and Reform Committee and the firmly portion of founding a capital once made comments and instructions and represented dme " can use ", but, can produce when pure Dimethyl ether burns and blow out phenomenon, and its vaporization heat is higher, combustion instability, and to macromolecular material, there is swelling effect, the problem therefore " how used " never solves.Although country puts into effect relevant preferential, but in applying, the technical indicator of dme as domestic fuel and the imperfection of auxiliary facility, cause dme really can not move towards market, the working rate of enterprise is by subtracting, the turnout in the whole nation only accounts for about the 20-30% of production capacity, and more than 90% dme can only lean on blending to apply in LPG, if only lean on the ratio blending LPG of 20% to find the outlet of dme industry, for the dme industry producing nearly 1,484 ten thousand tons per year, not only as an utterly inadequate amount, greatly limit the development of dme especially, and traditional energy is substituted for clean energy cut the dirty development reduced discharging hundred evils and none is sharp especially.
Chinese patent CN101935556A discloses a kind of low-carbon energy-saving gas, be made up of dme 60-80, refined methanol 20-36, additive 1-3, nano nickel liquid suspension 0-0.2, wherein additive is propyl ether 15-25, ferrocene 0.3-0.7, naphthenate 1-2, anti-coking agent 1-3, sanitas 1-2, detergent dispersant 1.5-2.5, stablizer 8-12, stopper 1.5-2.5, isocaprylic acid lanthanum 1-1.4, nano nickel liquid suspension 0.2-0.4.This low-carbon energy-saving gas is compared with DME blending LPG, although the ratio of DME accounts for 60 ~ 80%, still will add the refined methanol of 20 ~ 36%, and cost is higher on the one hand, still there is problem not fully in addition to the utilization of dme.
On this basis, Chinese patent CN101319157B discloses a kind of environment friendly energy conservation fuel, specifically with the mixture of dme or dme+acetone and/or Sweet natural gas and/or oil liquefied gas for main fuel, add that to account for fuel mass ratio be 0.1 ~ 1.0% energy-conserving synergistic agent again, wherein the component of energy-conserving synergistic agent is: methyl tertiary butyl ether 10 ~ 20, tert.-butyl acetate 5 ~ 15, cyclopentanone 10 ~ 20, sherwood oil 10 ~ 20, acetone 10 ~ 20, dimethylbenzene 5 ~ 15, ethanol 5 ~ 15, tertiary butyl Ferrocene and its derivative 1 ~ 10, methyl cyclopentyl-dialkyl-tricarbon manganium 1 ~ 10, hydrogen peroxide 1-20.Although this environment friendly energy conservation fuel can increase the content of dme, further research shows, this fuel combustion and not exclusively and there is certain corrodibility in fuel, burning has residual and alternative acetylene for cutting time, cut surface is rough.Especially in its component, acetone is easy poison product processed, and dimethylbenzene also has certain carinogenicity.
