Abstract
The invention discloses a composite diesel composed of the components of, by weight, diesel, dimethyl carbonate, tert-butanol, isobutanol, common kerosene, absorber oil and heavy aromatic hydrocarbon. The composite diesel provided by the invention has relatively high flash point, solidifying point and cetane number. The miscibility of the components is good, and the corrosivity is low. The diesel can be used for replacing a common diesel fuel. The composite diesel provided by the invention meets the indexes in automotive diesel GB19147-2009.
Description
Technical field
The present invention relates to diesel oil field, particularly a kind of compound diesel and preparation method thereof.
Background technology
Oil is as a kind of Nonrenewable resources, and excessive exploitation and use, the use especially on vehicle fuel, has caused the severe contamination of environment.Under current severe situation, synthesis compound diesel, as a kind of vehicle fuel alternate resources, effectively can slow down the usage quantity of oil, reduce the pollution to environment, reduces the cost of use etc. of fuel.But the development of current compound diesel project large breakthrough, mainly there is dynamic property difference, mutual solubility is poor, flash-point is low, insufficient, that price is high problem of burning, and hinders the development of synthesis compound diesel always.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of compound diesel and preparation method thereof, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technical scheme: a kind of compound diesel, is characterized in that: be made up of the component of following weight part: diesel oil 20-40 part, methylcarbonate 2-5 part, trimethyl carbinol 1-3 part, isopropylcarbinol 1-3 part, common kerosene 10-20 part, heavy aromatics 80-100 part.
Prepare a method for compound diesel, comprise the following steps:
(1) grease pre-treatment: diesel oil, common kerosene and heavy aromatics are put into agitator and stirs in advance;
(2) preparation of alcohol sodium solution: dehydrated alcohol and sodium weight part ratio are 2:1, is warming up to 80 DEG C of back flow reaction 3h;
(3) pretreated for step (1) grease heating in water bath to constant temperature after 70-90 DEG C is added under the agitation condition of 80r/min alcohol sodium solution prepared by step (2), after stirring reaction 1-3h, add methylcarbonate, the trimethyl carbinol and isopropylcarbinol, and then under 90 DEG C of conditions in and stratification 18-24h;
(4) upper solution of step (3) gained is carried out under 1.5KPa pressure condition underpressure distillation and reclaim ethylene glycol, suction filtration removing sodium, then repeatedly wash 4-7 time, final drying 15-20h, obtains the product of faint yellow clear, i.e. compound diesel.
Adopt the beneficial effect of above technical scheme to be: in compound diesel of the present invention, the ferrocene added improves the dynamic property of compound diesel, serve and reduce nozzle deposit carbon and combustion-supporting effect; The trimethyl carbinol added, isopropylcarbinol, these organism can improve the mutual solubility between each component, and improve the condensation point of diesel oil, wherein isopropylcarbinol can also reduce the content of sulphur in fuel, reduce the discharge of objectionable impurities SO2; Methylcarbonate can greatly reduce or basically eliminate diesel combustion flue dust, can reduce the pollution of diesel combustion to environment, improves diesel engine efficiency of heat engine simultaneously; The washing oil added can improve the flash-point of compound diesel significantly, also improves calorific value; The common kerosene (fuel kerosene) added and diesel oil, improve the calorific value of compound diesel, and kerosene burning rapidly, temperature, completely, the cold starting property of compound diesel can be improved, and few, the not easily coking of carbon deposit after burning; The heavy aromatics added can improve the calorific value of compound diesel greatly, and compound diesel is burnt completely.
