Abstract

The present invention provides the use of ferrocene and/or ferrocene derivatives as an additive to heavy-grade fuels for high-compression, auto-ignition internal combustion engines.

Description

The purposes of ferrocene
The present invention relates to the purposes of ferrocene and/or ferrocene deriv, they are used as the additive of the high quality automotive fuel of high compression self-burning type engine.
In the retrieval of the known references of ferrocene and derivative thereof, ferrocene and method for making thereof are described in " Nature " 168 (1951) the 1039th pages first.Subsequently, ferrocene and derivative thereof, and corresponding manufacturing process have become the theme of many patents, and for example US 2 650 756, and US 2 769 828, and US 2 834 796, and US 2 898 360, and US 3 035 968, US 3 238158 and US 3 437 634.
Learn that from patent documentation ferrocene can advantageously influence combustion processes simultaneously.In German Patent 3418648, except many other compounds, also mention that ferrocene (dicyclopentadienyl iron) is as possible additive, so that fuel oil combustion reaches optimizing, help oil fuel to carry, and promote the perfect combustion of oil fuel through burner.
In United States Patent (USP) 4 389 220, disclosed a kind of method of regulating diesel motor.20 to 30ppm ferrocene are added in the diesel oil fuel, remove the carbon-containing sediment in the combustion chamber by this, and prevent that it from forming again.Find that simultaneously because the result of this measure, the fuel consumption of each range ability can reduce by 5%.Diesel oil fuel one speech in this example is the fuel that is called " Number 2 fuel oil " according to ASTM.The fuel of this type is the middle distillate from the petroleum refining program, and can obtain with " diesel oil " title in the service station.Four-cycle diesel engine such as launch vehicles such as tourist coach, motorbus, commercial carriers often adopts this kind fuels run.This fuel meets DIN 51601 standards, and is similar EL oil fuel on its quality.Therefore, it is a kind of intermediate fuel.
High quality fuel system supplies with more greatly and engine use more at a slow speed, for example uses in boats and ships or power station.The problem of Chan Shenging is herein, and the performance of downstream units can affect adversely because of carbon-containing sediment.This kind unit comprises particularly turbine charging machine and heat exchanger.But, for the settling on valve, the piston ring and in fuel chambers, also be undesirable, because of it may cause the reduction of motor performance, and/or cause the wearing and tearing of the part be concerned about to increase.
The objective of the invention is for above-mentioned settling is reduced to minimumly, or help its removal.
Above-mentioned purpose of the present invention realizes in the following manner: provide the purposes of a kind of ferrocene and/or ferrocene deriv, used as the additive in the high quality automotive fuel of high compression self-burning type engine.It is 0.9 to 1.01kg/dm that the present invention can be applicable to particularly have proportion 3The additive of fuel.
Ferrocene confirms to be particularly advantageous surprisingly as the purposes of additive, particularly uses the big engine of this type of heavy fuel operation, promptly, having the total power of driving is 400 to 100, and 000KW is preferably 15,000 to 50,000KW, and particularly surpass 30, the engine of 000KW.
Usually, above-mentioned sedimental problem is to increase along with the increase of heavy fuel.In the situation of this fuel, use ferrocene as additive, verified surprisingly system is effective especially.
According to purposes of the present invention, be particularly conducive to following grade, this grade system is commonly referred to marine fuel oil, " C " level oil fuel, marine diesel oil fuel or distillation marine diesel oil fuel.From then on the title of fuel grade as can be known, it mainly is to be used for the ship engine that turns round.
Described fuel can be the air distillation product that for example derive from crude oil, derives from vacuum distilling or derives from the residue of catalytic pyrolysis factory.The proportion of this fuel, particularly 0.9 to 1.0kg/dm 3Scope in.This fuel can be classified with reference to ISO82 17 more accurately.Be divided into two kinds of fuel according to this standard, i.e. so-called distillation bunker fuel (overhead product fuel peculiar to vessel) and so-called heavy residual fuel.Give the name of DM type for first kind, give the name of RM type for second kind.Some pattern lists as follows by way of example, lists its critical nature, for example proportion, viscosity, sulphur content and carbon residue.

All DM and RM type, the fuel that all can be used as in the scope of the invention uses.
Being permitted the marine engine of great on long voyage ship, is that two-cycle engine and the present invention are specially adapted to this kind engine.Thereby the present invention can be extended to and use ferrocene and/or ferrocene deriv, as in order to the additive in the fuel of running two-stroke engine.When this engine was slow speed engine, particularly in this kind situation, the speed that this slow speed engine has was that per minute 900 to 50 changes, and being preferably 200 to 50 changes, and particularly top speed is that per minute 100 changes or still less.But good result also can be reached by interpolation operation according to the present invention at the engine with fair speed and in Otto cycle engine.And the present invention can be extended to use ferrocene and/or ferrocene deriv, as the additive in the fuel of Otto cycle engine.
Good result system is reached by the ferrocene that adds 1 to 100ppm.When interpolation was lower than 1ppm, its effect was not remarkable, thus with the fuel ratio that does not use additive down, not talkative have an improvement in fact.Interpolation at additive surpasses under the situation of 100ppm, has reached its limit, and under this limit, any extra additive can't cause any noteworthy additional effect.Usually be preferably 5 to 50ppm scopes.The optimum scope is 10 to 30ppm.This additive adds operation can be reached in the following manner, additive is dissolved in the part of fuel, then with this solution via for example volume pump, be circulated to again in this fuel main flow.
Can at least partly use the capable biological substitution ferrocene of ferrocene.Ferrocene deriv is the compound derived from this ferrocene parent, and wherein additional replacement base system is disposed on one or two cyclopentadienyl rings.The example is ethyl dicyclopentadienyl iron, butyl ferrocene, ferrocenyl methyl ketone and 2,2-two-ethyl dicyclopentadienyl iron base propane.
Advantage of the present invention is, from used high quality fuel, and from the settling of lubricating oil, all effectively reduced.
Downstream units, for example turbine charging machine and heat exchanger, and engine part, for example valve and piston ring, its performance can affect adversely because of settling, and part reaches considerable.For removing settling, often need considerable labour and expense.Therefore, for example, merely hit through the big deep-sea going vessel of being everlasting, with the nutshell pulverized or even rice be blown in the evacuation circuit, with cleaning downstream turbine charging machine.Most settling is by this kind what is called " soft jetting action ", and removes from the blade wheel and from the upstream nozzle ring.Said procedure often is to carry out every day, and if necessary, what for, keep full engine load simultaneously to every day twice.But this kind method for cleaning often is inadequate.Therefore, carry out in addition with water washing, about one month once, or if need then more frequent.Because tying up to when reducing engine loading, this kind laundry operation carries out, so always relate to the delay of boats and ships.During this laundry operation, water system is taken turns through the nozzle upstream and the blade of nozzle ring, and introduces in the evacuation circuit.This washing operation is to relate to turbine charging machine and other parts are applied considerable pressure, and this is because due to its thermal shock effect.Therefore, it is minimum to attempt that generally this kind washing operation is reduced to.The general required time of this kind laundry operation is about 2 to 3 hours.About the factor that instructs of this point, be to be the transparency of water behind this rinse step simply.In this connection, these washing water usually can be significantly by severe contamination 1 to 2 hour.Owing to use according to the fuel that contains ferrocene as additive of the present invention, it is unnecessary making " soft injection " and this washing operation become usually.This can protect described unit, and does not have the restriction on any performance, and can save time and lower the labour and drop into.
When the performance of turbine charging machine affected adversely because of settling, many problems may take place.The efficient of this turbine charging machine, and the efficient of whole machine can be lowered, so that higher fuel consumption takes place.This settling can cause speed to reduce, and under extreme case, can make one or more of blade wheel of this turbine charging machine stop.In the situation of machine, be that this susceptor system makes from the exhaust of a plurality of cylinders and gets together by the exhaust of supplying in its blade wheel from common exhaust susceptor with a plurality of turbine charging machines.If this gas is uneven distribution, this is owing to change due to the resistance to flow, and latter system causes because of settling successively, then speed reduction, the fluctuation on speed, or the considerable difference on speed between coupling turbine charging machine, or even stop, all may taking place.Above-mentioned must returning because sedimental problem can cause the prematureness fatigue of materials, or under extreme case, cause the material fracture.In thick and heavy especially sedimental situation, this also can occur in be not equipped with a plurality of turbine charging machines than in the small machine, irregular speed, i.e. ambiguity running can cause extremely strong vibration, it can cause the damage of materials on bearing and other machine parts at short notice.
Though the inhomogeneous settling on the blade wheel, may not necessarily cause speed to reduce or speed difference, but in the situation of a plurality of turbine charging machines, because the result of mishandling, it can cause does not really expect vibration, and this vibration also may be the reason that increases wear rate.
Under the situation of not adding, also can find in downstream heat exchanger that settling ties up on this heat-exchanger surface to form that this settling is decided according to its thickness, can hinder heat exchange according to additive used in the present invention.Be mainly carbon-containing sediment, also must often remove, its mode is to wash with water, uses cleaning additive, for example CuCl according to circumstances 2Solution.Contain the fuel of ferrocene owing to use according to the present invention, make sedimental formation greatly reduce as additive.When over time, longer in the situation of this technology current state of this time ratio, and washing operation becomes in case of necessity at (for example in graving dry dock) really, can find that its settling can more easily be removed after using according to the fuel that contains additive of the present invention.Its reason is to have changed this sedimental composition.Can find when having the fuel of additive with use settling relatively down, this settling has higher the ash content of coal, than low heat value and than low carbon content.This settling seemingly has the hydrophobicity than low degree, because of it contains less oiliness or like oily composition.
Usually, this kind washing operation of heat exchanger or boiler is every two years to quarter in boats and ships to do on the graving dry dock to carry out when regulation is maintained with the work of inspection at the latest.But, under normal circumstances, between two graving dry dock middle parts, all need extra laundry operation five or six times.If use the present invention, then can exempt this extra laundry operation.
Below further by limiting examples with reference to description of drawings the present invention.Accompanying drawing 1 is the exhaust approach that the marine engine of above-mentioned grade schematically is described.This figure be explanation have whole 10 cylinders (2) start lathe (1).In each situation, will in so-called exhaust " susceptor " (3,4,5), get together, and cause turbine charging machine (6,7,8) individually from the exhaust of 3 or 4 cylinders.With flowing out the exhaust airstream of this turbine charging machine, in vapor pipe (9), to get together, the so-called exhaust " boiler " (10) of flowing through then wherein is to arrange heat exchanger (11,12,13), can produce high pressure, middle pressure and low-pressure steam by it.Exhaust system leaves this system by funnel (14).
The present invention successfully tests on container ship, and its result is as follows:
The technical information of these boats and ships:
60,000 registration long tons
The technical information of its engine:
Output: 33,000 kw
Cubic capacity: 10 Qi Gang @1.6m 3
Speed: maximum 90rpm
The speed of turbine charging machine: about 10,000rpm
Consume: about 6t/h, under full load
Under initial state, the turbine charging machine of this marine engine is that mat " soft injection " is thoroughly cleared up with washing operation.Do not carrying out after about 3 months, carrying out washing operation under any middle removal treatment.Though it is also inessential that this washing operation is sayed from technological standpoint, because this whirlpool opinion charging machine is done to such an extent that order is satisfied, carrying out this operation is to provide about polluting the situation of (settling) degree.Though As-Is according to this technology, it must be based on every day, carry out " soft injection " operation, reach one month once, carry out washing operation, between its operational period, used washing water still were subjected to severe contamination 1 to 2 hour, but in present circumstances, waived all removal treatments are gone through about 3 months (85 days), but just keep transparent when even so, its washing water begin always.Can obtain like this drawing a conclusion, during indication in, in fact deposit-free forms.Even can't also show no dirt deposition or significantly reduce the dirt deposition to use the position that method for cleaning arrives at always.
In the situation of heat exchanger, can find to form seldom settling by visual type.Situation possible so far during with the use washing operation is relatively more following, can easier and promptly remove established settling.
In addition, on piston ring and valve, do not see any settling with visual type.
