Description
Technical field
The present invention relates to a kind of solubility promoter, relate in particular to a kind of methyl alcohol straight-run spirit solubility promoter.
Background technology
Oneself becomes the pure importer of oil 1993 Nian Qi China, and within 2010, crude oil in China net importation amount breaks through 200,000,000 tons first, and externally interdependency exceedes 55%.That methyl alcohol has is cheap, synthesis technique simple, theoretical mixture gas calorific value is higher, transportation property is good and pollute the features such as low, belongs to clean fuel, and therefore replace oil with coal exploitation methyl alcohol vehicle fuel is significant.In recent years, production capacity of methanol and the output of China take coal as raw material all hits new peak.2000 to 2008, the annual speedup of methyl alcohol production capacity was 25%, and " 12 " methyl alcohol in mid-term production capacity is estimated to exceed 5,000 ten thousand t/a.Although methyl alcohol has more than 200 derivative trip product, its aggregate consumption is still less, and seriously drug on the market in market.Methanol device working rate in 2009 only has 1,752 ten thousand tons of 30%, 2010 year methanol outputs, start up rate 45%, and development Downstream Products of Methanol is imperative.
In the recent period, domestic multiple provinces and cities are as in succession applied methanol fuel in Hebei, Shanxi, Zhejiang, Xinjiang etc.2010, Hebei province's provincial standard " M15 Vehicular methanol petrol ", standard No. DB13/T1303-2010 were announced in the official approval of Administration of Quality and Technology Supervision of Hebei province.Zhejiang is national methanol gasoline pilot province.In the same year, through the adequate preparation in early stage, Zhejiang Province's methanol gasoline pilot is sold Launching Ceremony and is held in Quzhou, indicates that methanol gasoline (M15/93#) pilot in Zhejiang Province is sold formal startup.In December, 2012,100 newly-increased novel energy-saving environment-friendly buses of Changzhi City public transport company of Shanxi Province formally put into effect.This time the new bus of changing adopts diesel oil, methyl alcohol double fuel power, and exhaust emissions reaches Eu III standard.
Current commercially available solubility promoter exists following point: less stable, be unfavorable for that methanol gasoline stores for a long time, and be prone to demixing phenomenon compared with cryogenic region in the winter time; Versatility is not strong, and most solubility promoters transfer a certain model methanol gasoline configuration to, and majority is in the lower or higher situation of methanol content; Water resistant phase separation performance is poor, Xuzhou Yong Sheng Energy Science Co., Ltd methanol vapour diesel oil additive only has the report of M15, economic benefit is not high, added in M40 methanol gasoline under equal test conditions, chance water 0.5% is placed and within 10 days, is occurred turbid phenomenon, places phenomenon of phase separation occurs for 6 hours under-35 ℃ of low temperature.
Patent No. 102925223A, optimize technical scheme: Nitromethane 99Min. 10%, n-Heptyl alcohol 30%, phenylfluoroform 30%, n-Octanol 30%, gained methanol gasoline has good adaptability ride comfort, dynamic property, economy, the feature of environmental protection and security, its storage period is long, manufacture craft is simple, normal temperature and pressure, easy to operate, but in this patent solubility promoter, exist containing harmful elements such as N, F, in combustion processes, easily produce environmentally harmful gas.Patent No. 102977949A, the water resistant scheme that is separated is proposed: this resisting phase separation agent is refluxed after 4～5h and obtained by the polyethenoxy ether class tensio-active agent Hybrid Heating of 15～25wt% methoxy ethoxy methane mixture, 30～40wt% methylal, 20～30wt% isooctyl alcohol, 15～25wt% dimethylbenzene and 0.1～0.5wt%, finally obtain at 25 ℃ of temperature, solubization is 0.75% methanol gasoline, but this technical scheme is comparatively complicated, and preparation process is longer.Patent No. 102888259A proposes a kind of technical scheme: Virahol 10～15%, isooctyl alcohol 40～70%, methyl tertiary butyl ether 2～10%, tetrahydrochysene bark mutter 2～10%, dimethylbenzene 5～15%, metal corrosion inhibitor 0～20.5%, rubber swelling inhibitor 0.1～0.4%, detergent-dispersant additive 3～10%, antifriction lubricant 0.5～2%, oxidation inhibitor 0.05～0.3%, adopt the methanol gasoline octane value of this additive configuration high, can be mixed with 90#, 93#, 95#, 97#, 98# series product.This additive raw material is selected reasonable ratio, and contains detergent-dispersant additive, can effectively avoid methanol gasoline to occur that weight is unstable, the easily situation of layering, but this technical scheme additive amount is larger, and cost is higher.
