Description
Technical field
The invention belongs to the liquid carbon-containing fuel technical field, be specifically related to the liquid carbon-containing fuel that contains additive of oxygen containing organic compound.
Background technology
At present world's crude oil is in short supply, the developing rapidly of automotive industry, and oil price rises steadily, especially in recent years more outstanding, the new highest record in history appears in oil price, and it is predicted that the situation of following oil fuel shortage also will continue to the new forms of energy appearance, so economize on oil is the main flow in the world, concerns international people's livelihood major issue.
Gasoline is the traditional fuel of automobile always, but its source---oil is a kind of non-renewable resource.It is predicted that by the rate of increase estimation of present oil production rate, global oil storing amount will consume 80% of total amount about 2015-2035 greatly.Therefore, it is imperative to seek a kind of new automobile fuel.Methyl alcohol has the diversity of synthesis material, pollute during burning little, higher octane value is arranged, therefore, promise to be following alternative motor fuels most.But at present still can not one the step instead of gasoline, but as a kind of transition fuel.Exploitation uses alcohol ether gasoline not only to help environment protection, and higher economic return is arranged.Research octane number (RON) is the composite target of fuel, and the octane value of methyl alcohol is up to 112.Methyl alcohol is large Organic Chemicals, and the aboundresources wide material sources can transform synthetic by coal, the Sweet natural gas preparation, also can produce by timber even rubbish, countries in the world are for saving petroleum resources, from last century the '30s just begin methanol fuel is goed deep into extensive studies.Emergence along with China's economic, research application to methanol fuel obtains important breakthrough technically, as M15, the M30 of Luohe petrochemical industry Group Co.,Ltd development research, the clean methanol gasoline application in a big way in practice of different ratioss such as M50, M65.
Since the eighties in last century, various countries are that oil crisis is found a way out, to the existing breakthrough understanding of methanol fuel.Methanol gasoline is that clean gasoline is in many national commercializations such as the U.S., Germany, Italy, Australia, Brazil now, wherein the M15 methanol gasoline is once in German and Northern Europe broad scale research, demonstration, and auxiliary construction transnational M15 service station, high-proportion methanol fuel is considered to comparatively ideal proportioning, because it has remarkable economic efficiency and environmental benefit.
But, discover, with the increase of methanol content in the methanol gasoline mixture, the intermiscibility variation, phase separation temperature rises very fast.When methanol content reached 40%, phase separation temperature reached maximum value; When quantity of methyl alcohol continuation increase, the performance that mixes improves, and phase separation temperature descends rapidly.This is because the water tolerance of gasoline is minimum, when methanol content after a little while, mainly exist the problems of dissolution between water and gasoline in the mixture; After can reaching the master control status with the methanol content that water dissolves each other, water tolerance increases in the mixture, thereby phase separation temperature descends.
In addition, sneaking into micro-moisture in the methanol gasoline mixture, is very big to the destruction of its intermiscibility.Moisture content in phase separation temperature and the mixture is proportional substantially, the moisture of every increase by 0.1% in mixture, and a temperature that mixes will raise about 10 ℃.For M15 alcohol ether gasoline fuel, the minimum temperature that can keep mixing is-5 ℃, when temperature rises to 20 ℃, as long as the moisture of adding 0.14% will produce is separated, and visible moisture is sizable to the destruction of intermiscibility.Therefore, when produce using carbinol gasoline fuel, be strictly on guard against that moisture content sneaks into.
The adding of various solubility promoters all can significantly reduce the phase separation temperature of M15 alcohol ether gasoline, has alleviated the production of methanol gasoline mixed fuel, the intermiscibility contradiction in the application basically.
