Description

A kind of hybrid diesel fuel and preparation method thereof
Technical field
The present invention relates to fuel technology field, particularly relate to a kind of compound diesel and preparation method thereof.
Background technology
Diesel oil commonly uses the energy in every field extensive application as one.Carbochain due to the hydrocarbon component in diesel oil Long, containing reasons such as unsaturated hydrocarbons, internal combustion engine is generally difficult to burning completely, efficiency of combustion is the highest, tail gas smog greatly, easily amass Carbon, greatly pollutes ecological environment.It addition, catalytic pyrolysis component is more in diesel oil, easily generate insoluble in long-term storage Property colloid, residue and deposit, these further result in the insufficient of burning, and exhaust smoke level is big.
For promoting the burning completely of diesel oil, improving efficiency of combustion, minimizing tail gas content, the most conventional way is at diesel oil Middle interpolation diesel oil detergent.With the presence of diesel oil detergent toxicity and price higher, some diesel oil detergents can cause combustor Carbon distribution increases, and effect is not the most very good.Additionally, along with the increase of crude oil energy resource consumption, all universal face of much countries of the world Face energy shortage, the situation of even shortage.How increasing efficiency of energy utilization is that people generally face and urgently to be resolved hurrily asking Topic.
Summary of the invention
For problems of the prior art, it is an object of the invention to provide that a kind of deposit is few, burning fully, tail The compound diesel that air dry is clean.
The present invention also provides for the preparation method of a kind of compound diesel.
For reaching object above, the present invention adopts the following technical scheme that.
A kind of hybrid diesel fuel, it is characterised in that be made up of than the raw material of percentage ratio volumes below: diesel oil 60- 75%, biodiesel 20-30%, dibutyl phthalate 2-8%, oxalic acid 1-5%, methanol 1-3%, isooctyl ester nitrate 0.01-0.05%.
As with improvement, described biodiesel is mixed by the Petiolus Trachycarpi oil after refining, waste oil, Petiolus Trachycarpi oil and waste oil Percent by volume be respectively as follows: 40% and 60%.
As with improvement, described hybrid diesel fuel is made up of than the raw material of percentage ratio volumes below: diesel oil 65-70%, Biodiesel 20-25%, dibutyl phthalate 5-8%, oxalic acid 2-5%, methanol 1-3%, isooctyl ester nitrate 0.01- 0.05%.
As with improvement, described hybrid diesel fuel is made up of than the raw material of percentage ratio volumes below: diesel oil 68%, biology Diesel oil 22%, dibutyl phthalate 5%, oxalic acid 3%, methanol 1.95%, isooctyl ester nitrate 0.05%.
A kind of hybrid diesel fuel preparation method, it is characterised in that by following proportioning first by biodiesel and O-phthalic Dibutyl phthalate mix homogeneously, is then sequentially added into oxalic acid, methanol, isooctyl ester nitrate obtain mixture, the most under agitation will be mixed Compound joins in diesel oil；Described proportioning is: diesel oil 60-75%, biodiesel 20-30%, dibutyl phthalate 2-8%, oxalic acid 1-5%, methanol 1-3%, isooctyl ester nitrate 0.01-0.05%；Described biodiesel by the Petiolus Trachycarpi oil after refining, Waste oil mixes, and the percent by volume of Petiolus Trachycarpi oil and waste oil is respectively as follows: 40% and 60%
The invention has the beneficial effects as follows:
The applicant passes through numerous studies, it is provided that the hybrid diesel fuel of a kind of ratio optimization, by the conjunction of each component Reason proportioning and interaction so that the efficiency of combustion of hybrid diesel fuel is high, and imperfect combustion Hydrocarbon is decreased obviously. Especially, when biodiesel is mixed by the Petiolus Trachycarpi oil of 40% and the waste oil of 60%, overall performance is more excellent.
