Abstract
The invention discloses a fuel additive. The additive formed under the combined action of a water binding agent, an octane enhancing additive, an antioxidant, a detergent dispersant, a resist, an alcohol ether solubilizer, a caloric value enhancer, a combustion improver, a defoaming agent, an detonation inhibitor and a drier can be mixed with dimethyl ether to form a combustive fuel for substituting natural gas, liquefied petroleum gas and the like; and pure dimethyl ether which cannot combust in the beginning can completely combust at current, meanwhile, the blasting phenomenon caused when the pure dimethyl ether combusts is avoided, no gasification deficiency, corrosion, toxicity, black smoke as well as eye fumigating and pungency phenomena are caused, the fuel additive is stable in combustion and capable of completely meeting the requirement for civil use, and the igniting efficiency of the fuel additive is up to the national kitchen range inspection standard. The fuel additive provided by the invention is added into 0.5-2% of fuel gas according the mass content; and compared with liquefied petroleum gas, the formed fuel gas has the advantages of good safety performance, high comprehensive caloric value, no carbon deposition, no residual liquid and the like.
Description
Technical field
The present invention relates to the derived energy chemical technical field, particularly a kind of fuel dope and use its industrial or civilian low-carbon (LC) clean fuel.
Background technology
The world today faces two large global problems, the one, petroleum-based energy crisis, the 2nd, environmental pollution.The explored reserves of Global Oil are 1,421 hundred million tons, by nearly 10 annual year 35.6 hundred million tons of the amounts of adopting, at most also can keep 40 years.The China's oil reserves are limited, become net import of oil state since 1993, annual China imported crude oil was 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 interdependency of the energy has entered the energy early warning phase up to 55%, the aggravation of this situation will seriously restrict China's expanding economy, even can have influence on the national defense safety of China.China's vehicle guaranteeding organic quantity was 20754.6 ten thousand in 2011, do fuel 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 that causes gray haze, photochemical pollution, the urgency of Motor Vehicle Pollution Prevention highlights day by day.In February, 2012, " ambient air quality " of the new revision of State Council approved issue proposes higher requirement to fine particle in air (PM2.5) control, and Motor Vehicle Pollution Prevention becomes essential domain.Therefore, develop the imbalance between supply and demand that alternative clean energy not only is conducive to alleviate China's oil, reduce dependence on foreign countries for oil, can also effectively 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 that becomes from coal-based feedstock conversion, becomes the carbon-Chemicals of the superior performance that recent domestic competitively develops.(English full name is Liquefied Petroleum Gas as liquefied petroleum gas (LPG), be called for short LPG) and the alternative fuel of petroleum-type, dme is to have the chemical similar with the physical properties of LPG and enriching in view of the coal in China reserves, the source that makes dme is horn of plenty more, more optimizedly DEM itself contains oxygen, only has C-O bonding c h bond in molecular structure, so the DME sufficient combustion, carbon distribution not, 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 that becomes 21 century that is supposed to has boundless prospect.

By the end of the year 2010,60 of China total dme manufacturing enterprises, 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, China pays much attention to the exploitation of dme.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 the dme value added tax " in June, 2008, declaration was adjusted to 13% with the dme VAT rate by 17% time from 1 day July in 2008.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.Expression dme " can with " was once made comments and instructions by National Development and Reform Committee and the section of founding a capital firmly, and still, pure Dimethyl ether can produce when burning blows out phenomenon, and its vaporization heat is higher, combustion instability, and macromolecular material is had swelling effect, the problem of therefore " how using " never solves.although country puts into effect relevant preferential, but in applying, dme is as the technical indicator of domestic fuel and the imperfection of auxiliary facility, cause dme can not really move towards market, the working rate of enterprise is by subtracting, the turnout in the whole nation only accounts for the 20-30% left and right of production capacity, and the dme more than 90% can only lean on blending to use in LPG, if only depend on 20% ratio blending LPG to seek the outlet of dme industry, for the dme industry of producing nearly 1,484 ten thousand tons per year, not only as an utterly inadequate amount, greatly limited especially the development of dme, cut the dirty development that reduces discharging hundred evils and none profit especially and substitute traditional energy for clean energy.
Chinese patent CN101935556A discloses a kind of low-carbon energy-saving gas, be comprised 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 has accounted for 60 ~ 80%, still will add 20 ~ 36% refined methanol, and cost is higher on the one hand, in addition still there is the problem not fully in the utilization of dme.
on this basis, Chinese patent CN101319157B discloses a kind of environment friendly energy conservation fuel, specifically take the mixture of dme or dme+acetone and/or Sweet natural gas and/or oil liquefied gas as main fuel, add again that to account for the fuel mass ratio be 0.1 ~ 1.0% energy-conserving synergistic agent, 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 derivative 1 ~ 10 thereof, 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 studies show that, there is certain corrodibility in this fuel combustion also incomplete and fuel, burns when having residual and alternative acetylene to be used for cutting, and cut surface is rough.Especially in its component, acetone is easy poison product processed, and dimethylbenzene also has certain carinogenicity.
