Abstract
The invention relates to high-cleanness composite diesel oil and a preparation method thereof. The high-cleanness composite diesel oil comprises the following raw materials in parts by weight: 10-40 parts of low-temperature coal tar subjected to degenerating catalysis, 10-30 parts of solvent oil 200, 10-30 parts of kerosene, 20-80 parts of diesel oil and 0.1-0.3 part of isooctyl nitrate, wherein the low-temperature coal tar subjected to degenerating catalysis is obtained after low-temperature coal tar reacts in a reactor loaded with degeneration catalytic particles consisting of 55 percent of carclazyte and 45 percent of borax at 60 DEG C and two atmospheric pressures for 5-6 hours. The high-cleanness composite diesel oil of the invention has the advantages of abundant raw material source, low cost, simple production process, no corrosive chemical components, such as acid, alkali, and the like and no pollution to the environment and solves the problem of supply shortage of natural fuel. The invention can be directly used for various diesel engines.
Description
Technical field
The invention provides a kind of diesel oil substitute products.
Background technology
Diesel oil is the required fuel of diesel motor work, has a wide range of applications in every field.At present, diesel oil mainly refines by crude oil and obtains.Because crude oil is Nonrenewable resources, along with the continuous increase of crude oil consumption, the energy dilemma in the whole world is also serious day by day, makes the oil price height look forward to.Therefore, tap a new source of energy by all kinds of means and substitute energy become instant task.China is coal big country, has to enrich coal resources, and by the coalite tar that low-temperature pyrolysis obtains, its every component and diesel oil are very approaching, is good diesel oil substitute products.
Summary of the invention
Problem solved by the invention provides a kind of high cleanness composite diesel oil and preparation method thereof cheaply, is used for alternate standard diesel oil.
The present invention is achieved in that described high cleanness composite diesel oil is made up of following weight percentages:
10～40 parts of coalite tars after sex change catalysis
10～30 parts of 200# solvent oils
10～30 parts of kerosene
20～80 parts of diesel oil
0.1～0.3 part of isooctyl ester nitrate
The present invention follows these steps to formulated:
1. will put into reactor through the coalite tar after the sex change catalysis earlier;
2. will put into reactor by the 200# solvent oil and the kerosene of proportioning weighing again, and add the isooctyl ester nitrate as catalyzer simultaneously, 60 degree, 2 barometric points reacted 4-8 minute down;
3. add diesel oil by proportioning at last and stirred 5-6 minute, make high cleanness composite diesel oil;
In the reactor that the sex change catalysed particulate of being made up of by weight percentage 55% carclazyte and 45% borax is housed, reaction obtained after 5-6 hour coalite tar after the net change catalysis in the described step 1. under 60 degree, 2 barometric points by coalite tar.
Raw material of the present invention and effect:
Coalite tar: a kind of black that obtains in the coal low-temperature pyrolysis process or chocolate viscous liquid are a kind of complex mixtures of hydrocarbon polymer of high aromaticity.
Kerosene: by natural oil or artificial petroleum through fractionation or cracking and get.Multiple hydrocarbon mixture for C9～C16.
Isooctyl ester nitrate: a kind of colourless or transparent liquid organic solvent, can improve diesel-fuel cetane number, improve the combustionproperty of diesel oil, shorten ignition time, reduce burning-point, improve locomotive thermal condition dynamic property.
The sex change catalysed particulate: 55% carclazyte and 45% borax mixed the back oven dry with water and the canescence particle, decolouring, desulfuration are arranged, go the effect of distinguishing the flavor of.
Advantage of the present invention:
About 4,000,000 tons of China's coalite tar annual production at present, abundant raw material, the price of coalite tar is the price of GB diesel oil on the market also, and 200# solvent oil, kerosene are the byproducts of oil, the price of these raw materials also will be lower than GB diesel oil, thereby the cost of combined diesel oil of the present invention also will be lower than the cost of GB diesel oil.
High cleanness composite diesel oil of the present invention, sufficient combustion, powerful, the exhaust emissions cleaning can be directly used in all kinds of diesel motors.Simultaneously, production technique is simple, does not use aggressive chemistry compositions such as any acid, alkali, environmentally safe, and the waste residue that is produced after producing can be done fuel and use, and has good burning performance.The present invention has increased the kind of fuel, has solved the under-supply problem of natural fuel.
Show after testing, the every physical and chemical index of high cleanness composite diesel oil of the present invention meets the national standard of GB252-2000 fully, and following data are the detection data at the 0# compound diesel of Research Institute of Petro-Chemical Engineering's analytical test gained (component: 30 parts of the coalite tars after sex change catalysis, 20 parts of 200# solvent oils, 14.8 parts of kerosene, 0.2 part of isooctyl ester nitrate, 35 parts of 0# GB diesel oil).
