Abstract
The invention discloses a biodiesel pour point reducer composition as well as a preparation method thereof. The biodiesel pour point reducer composition is composed of span-series surface active agents and a diesel pour point reducer through mixing; and the raw materials are composed of 0-5% of span-20, 0-5% of span-40, 0-5% of span-60, 40-60% of span-80 and 30-50% of the pour point reducer by mass. The preparation method comprises the following steps of: mixing the raw materials, and stirring in aqueous thermostat at the rotation rate of 200 r/min for 10 min to obtain the biodiesel pour point reducer composition. After the obtained biodiesel pour point reducer composition is added into the biodiesel, a cold filter plugging point is reduced by 6-10 DEG C, and a condensation point is reduced by 7-11 DEG C. The biodiesel pour point reducer composition disclosed by the invention enhances exposure level of the biodiesel pour point reducer and a wax crystal, and improves the low-temperature fluidity of a biodiesel oil product.
Description
Technical field
The present invention relates to a kind of pour point reducer composition and preparation method thereof, more specifically saying so relates to a kind of pour point reducer composition that is used for the biofuel pour point depression and preparation method thereof and the application aspect the biofuel pour point depression.
Background technology
It is fine diesel oil substitute through carrying out fatty acid methyl ester or the ethyl ester fuel that transesterification reaction is processed with alcohols materials such as methyl alcohol or ethanol that biofuel is meant with raw oils such as waterplant greases such as oil crops, wild oil crops and engineering microalgae and animal oil and fat, waste cooking oils.Biofuel has caused the extensive concern of countries in the world as the alternative fuel of petrifaction diesel, has formed large-scale production in American-European countries.Yet the zero pour of biofuel is generally about 0 ℃; Regular meeting separates out because of the crystallization of fatty acid methyl ester and stops up transition pipeline and strainer at low temperatures; Hinder the normal operation of mover, the low-temperature fluidity that therefore improves biofuel is the problem that must face and solve in the biofuel research and development process.
Solve at present below the measure that the problem of biodiesel lower-temperature fluidity difference can take several kinds: 1) winterization is handled, and this method productive rate is lower, serious waste of resources; 2) change the biofuel structure, but its cost is higher, is difficult to realize industrialization; 3) sneak into a certain amount of refined diesel oil, the biofuel of 2%～20% volume(tric)fraction is joined condensation point is reduced.Need add refined diesel oil owing to improve the method for biodiesel lower-temperature fluidity ability, and China's refined diesel oil output is little, supply falls short of demand, so this method feasibility is little; 4) add cold flow improver because add-on is few, cost is low, easy to operate, become solve biodiesel lower-temperature fluidity can prefered method.Continue to use traditional diesel pour inhibitor mostly for biofuel pour point depressant aspect both at home and abroad; Lack to biofuel outstanding effect pour point depressant; Reason is that biofuel composition and diesel oil have a great difference; Contain a large amount of saturated fatty acid methyl esters, itself zero pour is higher, uses traditional pour point depressant poor effect merely.Diesel pour inhibitor is mainly the polymer of chain-like structure, and various groups are arranged on its side chain, comprises N-alkanes hydrocarbon chain, carbonyl that length is different.Generally believe, pour point depressant be through the absorption on wax crystallization surface or with the effect of its formation cocrystallization, change the brilliant shape and size of wax, prevent that wax intergranular bonding from forming three-dimensional network-like structure, thereby reach the pour point depression effect, improve the low temperature flowability of diesel oil.Adopt tensio-active agent and its pour point depressant commonly used on the market to carry out composite its dispersion effect on oil product wax crystalline substance that strengthens according to its mechanism of action; Thereby play the effect that strengthens the pour point depression effect; Class of department series of surfactants belongs to ester class non-ionics, itself is easy to be attached to cured crystalline substance of biofuel and pour point depressant surface, improves their surface property; Make tightr that pour point depressant contacts with cured crystalline substance, strengthen pour point depressant pour point depression effect thereby play; Owing to itself be ester class promoting agent, do not change other performance of biofuel on the other hand, have fabulous consistency with biofuel, pour point depressant, itself and pour point depressant be composite to play the obvious effect that improves biodiesel lower-temperature fluidity.
