There are two newses that taste about biology oil recently. It is Beijing time first on November 22, beijing flies to the airliner of Hainan aviation HU497 of Chicago to descend successfully, the aviation fuel that this plane place uses mixed kerosene of aviation of certain proportional live thing, its raw material comes from meal to waste oil, it is the ground channel oil that our common weighs. This is our country home change fuel to realize the flight that cross ocean from ground channel oily refine first. A additional in Shanghai happening, recently, the gas station point that gives virtuous area and Pudong new developed area begins derv of biology of pilot sale B5, this is the biology derv that eat hutch discards grease is made enter finished product oily terminal to sell the market first in home.
According to media coverage, the technical feedback that oil of two kinds of biology tastes is good: The plane of kerosene of use biology aviation need not undertake changing one’s costume or dress to engine, and can reduce carbon effectively to discharge, pilot says plane “ moves very smoothly to mix good ” ; Relevant researcher expresses, the car of use biology derv is mixed in dynamical sex discharge a gender to go up to agree basically with original derv, hydrogen of heavy metal, fine grained content, carbon, carbon monoxide discharge have reduce significantly, a few drivers also express satisfaction to using a result.
Biology oil tastes an advantage so much, did this mean promotion to rise to do not have obstruction? Not be of course. Look at present, the price state that these two kinds of oil taste has very big distinction, the manufacturing cost of biology aviation kerosene is traditional of kerosene of oil radical aviation 2 to 3 times, the price inevitable also taller; And pilot during the price of B5 biology derv is hit on foundation of common derv price 9.5 fold. Two kinds of different prices are moved toward, the prospect that can create two kinds of oil to taste probably differs somewhat.
Of course, the favourable price of B5 biology derv establishs the basics that supports in finance to go up, if government not allowance, the enterprise is met deficit. Want to popularize biology derv energetically, relying on governmental subsidy is not long apparently plan.
With most car advocate same, the future that oil of author opposite matter tastes supports wait-and-see attitude, wait-and-see reason is price element not just. The many our country year ago ever had popularized the gas that deserves to have 10% alcohol part, partial province is compulsory sale almost. The author more than 10 years ago drives to save churchyard to Shandong, can add alcohol benzine only, and go to Shandong a few this years again, cannot see almost. Also be “ to alcohol petrolic conduct propaganda in those days but good ” of maturity of second birth, technology, economic benefits, but in reality, people discovers it has many drawback, store for instance difficult, motivation outputs slow, price to wait without the advantage, cause alcohol benzine promotion to encounter difficulty. The biology derv nowadays, can also you have a lot of drawback? Car advocate people heart impeach Lv also is understandable, after all some of defect needs to pass period of time, and have the example ability system of full adequate amount come out now. #p#·ÖÒ³±êÌâ#e#
Everybody still should remember, the our country a few years ago has produced the situation of corn spurt in prices, this also is used with alcohol petrolic about, because produce alcohol to need a large number of corn, corn price produced linkage effect with oil price. The country mentions again this year alcohol benzine, print and distribute ” be produced about enlarging biology fuel alcohol and popularize use car to implement plan with alcohol petrolic ” , put forward the whole nation used basic implementation car alcohol benzine to be enclothed completely 2020. Putting forward this plan not to have nothing to do with the air pollution of instantly is, concerned personage thinks, can carry industry of development cellulose alcohol, solve the problem that straw burns.
Solve ground channel oily problem with biology derv, solve straw to burn with alcohol benzine problem, look very beautiful, but the problem is potential also just goes out to be here now: Because ground channel oil and straw are more dispersive, reclaim have very great difficulty, and raw material also is used not quite far, want mass production really, the likelihood still should use the crop such as corn. Original intention is for environmental protection, the result develops a space with commissariat contention, final likelihood is just the opposite to what one wished.
Current, china has been in study schedule to stop to sell fuel car, say from this meaning, biology oil tastes a likelihood is one kind transfers only product, their foreground has many capacious, still be an unknown.
