XOverall target only is 49% of a motor spirit; Oil consumption is suitable with gasoline when low cruise, more than 90 kilometers/hour the time, is better than gasoline, but fuel saving 20-35%; The per-cent of machine oil fuel oil consumption only is 3.2% of gasoline; The deterioration rate of its peak power of stress alternation reliability test of 400 hours, peak torque, three indexs of maximum oil consumption only is respectively 2.8%, 2.6% and 0.4%, be national standard require the deterioration rate 5% with interior be qualified, the per-cent of its machine oil fuel oil consumption (%) is 0.095, be better than≤3 national standard requirement, the detection data that this test obtains are that white gasoline is unapproachable; Through comparison and detection, this quality of fuel detection index all is better than the index in Beijing motor spirit provincial standard (DB11/238-2004) and the EN228-2004 of European Union (E) standard.
(2) fuel of the present invention is invited to have participated on January 6,27 days to 2007 December in 2006 " the 6th Chinese Song Hua River international ice and snow automobile challenge match " and " second Sino-Russian international automobile championship ", arrive nearly 4000 kilometers of Muscovite Khabarovsk and Komsomolsk stroke through Tongjiang from the Harbin as the appointment fuel of this race, successively experienced the subzero 40 ℃ severe cold and the test of complex road surface, the fleet that four cars of the said firm are formed obtains the team title of race.This methanol gasoline has demonstrated outstanding capability and performance in play, makes oil product obtain the favorable comment of Sino-Russian match hand, can prove that this oil product possesses good low temperature winter hardiness.
(3) source of the methyl alcohol in the fuel of the present invention variation, can produce by Sweet natural gas, petroleum naphtha, heavy oil or biology, also can pass through coal conversion, also can process by coal-seam gas and coke(oven)gas, it is abundant and have a higher octane value that methyl alcohol contains oxygen, do not need to consume a large amount of air in the combustion processes, discharge index is than motor spirit GB17930 and more environmental protection of vehicle-use alcohol gasoline GB18351.Methyl alcohol only is equivalent to 1/4 of gasoline on the price, and production cost is low, easily popularizes; Methyl alcohol is the use of fuel as an alternative, is applicable to various vehicles; Methyl alcohol can substitute the part oil fuel, reduces the dependence to petroleum import.
(4) the methyl alcohol calorific value is low in the fuel of the present invention, added methyl tertiary butyl ether in the fuel and remedied agent with the calorific value that weight ratio allotment in 2: 3: 5 forms by benzene mixed and light aromatic hydrocarbons and methylethylketone, fuel combustion is more abundant, make the calorific value of methyl alcohol obtain effectively replenishing, solved the oil product calorific value and descended and the dynamic property deficiency.
(5) methyl alcohol is the same with gasoline in the fuel of the present invention, is chemically all belonging to the moderate toxicity material, and methyl alcohol has been done the toxicity processing earlier before in adding other raw material to, adds methanol modifier, makes the usability safety and reliability of fuel.
(6) methyl alcohol is strong solvent in the fuel of the present invention; the metallic surface of automobile and rubber are moulded pad certain corrosive nature is all arranged; alkyl monosulfide phenates, zinc dialkyl dithiophosphate have been added in the fuel; improve the corrosive nature that fuel stops moisture and oxygen molecule that metal and rubber are moulded pad, the protective money metal surface delays corrosion.
(7) adding has delayed phenomenons such as oxidized, variable color, colloid by phosphoric acid ester and beta-naphthylamine effectively with the oxidation inhibitor that weight ratio allotment in 1: 1 forms in the fuel of the present invention, improve the oilness of Vehicular methanol cleaning fuel, reduce friction and wearing and tearing, prolong engine work-ing life.
(8) adding is allocated the mutual solvent that form by alkenyl succinic acid and alkylphenol polyoxyethylene with weight ratio at 1: 1 in the fuel of the present invention, makes the stability of methanol fuel stronger, prolongs the oil product shelf lives; Under general environment, the oil product storage time can reach more than 1 year.
(9) raw material resources diversification of the present invention, each refinery obtain 190 after all can extracting vapour, diesel oil in crude oil
#-200
#Solvent oil, superimposed wet goods petroleum by-product.
(10) ethanol is mainly derived from corn, barley, wheat, also can come from textile plant such as trees and grass, and ethanol belongs to renewable energy source, and ethanol is high oxygenated fuel, can increase the octane value and the discharge quality that improves petrol motor of gasoline.
In sum, fuel of the present invention meets national development in pluralism substitute energy policy, substitutes traditional energy with new forms of energy, substitutes the energy in short supply with biomass energy, substitutes fossil energy with renewable energy source, improves the proportion of substitute energy in energy structure.The basic raw material source diversification of this fuel, production technique is simple, easy and simple to handle, production cost is low, economic benefit and obvious social benefit, more important is that fuel of the present invention has added coal system methyl alcohol, renewable energy source ethanol and ether compound, improved the ability that China's reply soaring oil prices and oil supply are becoming tight, remedy the oil insufficiency of supply-demand of quick expansion, efficiently solve energy kind shortage problem, realized enterprise self-determining, technological innovation has realized scientific development, cleaning development, security developments and Sustainable development.
