Abstract
Methyl alcohol and smart tar that combined diesel oil adopts cheap cinder to transform, compound with heavy benzol and kerosene again, make 0-No. 40 oil that meet national standard, be added with isopropylcarbinol in the oil and be used to improve cetane value as mutual solvent, alkyl nitrate ester selected, high alkalinity alkylphenol calcium or overbased sulfonate etc. are ignition dope as neutralizing agent, succimide as ashless dispersant, naphthenate.Alkylbenzene sulfonate is a purification agent, optimizes five kinds of prescriptions with said components, makes the combined diesel oil that can be used for extremely frigid zones or raising rate of combustion or reduce various premium propertiess such as environmental pollution.
Description
The present invention relates to artificial synthesized diesel oil and preparation method thereof.
Artificial synthesized diesel oil had abroad appearred in recent years, domestic also someone utilizes methyl alcohol, sulphonated oil, gasoline synthesizes artificial diesel oil, as number of patent application is 89106267.X, name is called the patented technology of " combined diesel oil that is used for extremely frigid zones ", but it does not reach perfect and ripe, partly or entirely substitute oil with methyl alcohol or smart tar and make motor spirit (on the hydrocarbon fuel basis) though series of advantages is arranged, as more effectively utilizing motor spirit, combustion processes has minimum environmental pollution or the like, but, this mixed solution oil, it is the mixture of alcohols (10-15%) and gasoline or kerosene, exist stratified major defect, thereby close the acid in the oil in can not be effectively; And, because prescription is unreasonable, lacking due ignition dope, its cetane value is low, so be difficult for catching fire; In addition, owing to adopt sodium hydroxide as neutralizing agent, and equipment is had serious corrosive nature; Except that above-mentioned shortcoming, ash content is big behind this oil firing; Because of adopting phosphide to make purification agent and dispersion agent, can make exhaust touch coal when being used in vehicle and poison again.
In view of the above-mentioned shortcoming of existing artificial synthesized diesel oil, the present invention proposes one group and meets standard GB 252-64 fully, has the novel combined diesel oil of good use properties.
Main purpose of the present invention provides a kind of combined diesel oil, and it adopts cheap cinder to be converted into methyl alcohol and smart tar, again with heavy benzol and kerosene is compound forms through special processing.
Another purpose of the present invention provides a kind of combined diesel oil, and it adds isopropylcarbinol as mutual solvent on above-mentioned basal component basis, to solve the lamination problem of mixed oil liquid.
Another object of the present invention is to add alkyl nitrate ester selected to improve the cetane value of combined diesel oil on above-mentioned combined diesel oil basis.
Another purpose of the present invention is to add the organic bases additive in order to acid in the oil that neutralizes, to avoid the corrosion to equipment in above-mentioned combined diesel oil.
A further object of the present invention is to add the oil soluble organic metal salt as ignition dope with add succimide as dispersion agent in above-mentioned combined diesel oil, to reduce the ash content after the burning.
Further aim of the present invention is to add alkylbenzene sulfonate as purification agent in above-mentioned combined diesel oil, to remove burning postadhesion settling on equipment effectively.
The main body of the artificial combined diesel oil of the present invention is non-petroleum cracking products such as methyl alcohol, smart tar, heavy benzol and kerosene;
Lamination problem when mixing for solving alcohols and gasoline or kerosene adds the products of oxo synthesis isopropylcarbinol as mutual solvent, promotes that alcohol oil is miscible and does not make the combined diesel oil layering;
For overcoming the low shortcoming of combined diesel oil cetane value, the present invention adds the cetane number improver based on alkyl nitrate ester selected, general isopropyl nitrate, amyl nitrate, the isooctyl ester nitrate etc. of using, normal addition is the 1.0-7.5%(volumetric ratio), cetane value can improve 12-20.
Preventing aspect the equipment corrosion, for the fuel that prevents sulphur content higher (as 0.3-10%) forms heavy corrosion to engine, the present invention uses high alkalinity additive, commonly used have high alkalinity alkylphenol calcium, sulfuration high alkalinity alkylphenol calcium, a high alkalinity value calcium alkyl salicylate, overbased sulfonate, its alkali metal content be general homology type purification agent content 3-5 doubly, basic metal can be calcium, magnesium and barium, mainly is calcium.
The present invention has also added succimide as dispersion agent, and it does not have ash content after making the combined diesel oil burning, so claim ashless dispersant again, its consumption can reach 10-100PPM.Make oil become the colloidal solution state after adding this dispersion agent, have good dispersing property, thereby can not form the pipeline that greasy filth stops up oil filter and carries machine oil.
In addition, because the improvement of vehicle in recent years, increase crankcase ventilation installation and exhaust circulating device, make the settling in the vaporizer that the phenomenon that further increases be arranged, must add purification agent and dispersion agent and guarantee the works better of engine, past all is to adopt phosphide, thereby it is influential that work-ing life of coal is touched in exhaust, for this reason, the present invention uses alkylbenzene sulfonate (calcium salt, barium salt and magnesium salts), usage quantity is 100-200PPM, and it is a kind ofly can remove the sedimental purification agent that forms on engine chamber and the piston face effectively, and can not make and touch the coal poisoning and deactivation.
The present invention is again at high these characteristics of combined diesel oil ash oontent, added ignition dope to reduce burning back ash content and to improve combustionproperty, thereby reduce disadvantages such as over-emitting black exhaust and knot carbon, used ignition dope is the oil soluble organic metal salt, as cobalt naphthenate, calcium naphthenate and naphthenic acid barium salt, general addition is the 0.02-0.2%(capacity).
