Abstract
A fuel-oil coke slurry, its production and use are disclosed. The fuel-oil coke slurry consists of petrol coke 3-7 proportion, liquid medium 3-7 proportion and additive 0.3-1 proportion. The ash content is blow 1%. It's simple and convenient and can be used in various occasions.
Description
Technical field
The present invention relates to a kind of fuel, relate in particular to a kind of fuel-oil coking slurry, its preparation method and application, belong to chemical field.
Background technology
Existing refinery coke can be used as solid fuel, but can't replace oil (gas) to carry out spray burning.Existing coal water slurry is a kind of fuel slurry that is mixed by coal, water, additive, but in many occasions, such as calcar, high-grade kiln for ceramic tiles etc., can not use coal water slurry acts as a fuel, major cause is that the ash of coal water slurry is too high, also is unpractical below 1% even select for use washed coal under existing coal preparation technology condition ash to be reduced to.So need a kind of new fuel, the ash that is produced after this fuel combustion can be controlled at below 1% always,, be applied to require the occasion of ultra-low ash content in order to replace oil (gas) fuel.
Summary of the invention
The present invention's technical problem at first to be solved is to overcome the deficiencies in the prior art, and a kind of new fuel is provided, and the ash that is produced after this fuel combustion can be controlled at below 1%, can replace oil (gas) fuel, is applied to require the occasion of ultra-low ash content.
The present invention's technical problem at first to be solved realizes by following technological approaches:
A kind of fuel-oil coking slurry, form by the component of following weight part:
Refinery coke 3-7 part, liquid medium 3-7 part, additive 0.3-1 part.
Wherein, described liquid medium is selected from any in water, sanitary wastewater or the trade effluent, or more than one mixtures formed with arbitrary proportion in them.Described water does not have special requirement, tap water, rivers water or spring all can, comprise sanitary wastewater, trade effluent, as long as they in non-combustible impurity below 1 ‰.
Described additive is selected from Vltra tears, hydroxypropylcellulose, methylcellulose gum, stearic acid, oleic acid, alkylbenzene sulfonate, sulfonated alkyl naphathalene, alkyl phenol polyoxyethylene glycol ether vitriol, fatty alcohol polyglycol ether vitriol, ethoxylized fatty alcohol, ethoxylated alkylphenol, oxidation coco dimethyl amine, coco amine, the dimethyl lauryl amine, coco dimethyl amine, N-butter-1,3-diaminopropanes, in cetyltrimethylammonium chloride or the chlorination h-tallow trimethyl ammonium any, or their more than one mixtures of being formed with arbitrary proportion.
Preferably, the weight part of each component is:
Refinery coke 6-7 part, liquid medium 3-4 part, additive 0.5-0.8 part.
Used refinery coke and additive all can be bought from market and obtain among the present invention.
Another technical problem to be solved by this invention provides a kind of method for preparing above-mentioned fuel-oil coking slurry.
Another technical problem to be solved by this invention realizes by following technological approaches:
A kind of method for preparing fuel-oil coking slurry may further comprise the steps:
(1) take by weighing each raw material by following weight part:
Refinery coke 3-7 part, liquid medium 3-7 part, additive 0.3-1 part; Wherein, described liquid medium is selected from any in water, sanitary wastewater or the trade effluent, or more than one mixtures formed with arbitrary proportion in them; Described additive is selected from Vltra tears, hydroxypropylcellulose, methylcellulose gum, stearic acid, oleic acid, alkylbenzene sulfonate, sulfonated alkyl naphathalene, alkyl phenol polyoxyethylene glycol ether vitriol, fatty alcohol polyglycol ether vitriol, ethoxylized fatty alcohol, ethoxylated alkylphenol, oxidation coco dimethyl amine, coco amine, the dimethyl lauryl amine, coco dimethyl amine, N-butter-1,3-diaminopropanes, in cetyltrimethylammonium chloride or the chlorination h-tallow trimethyl ammonium any, or their more than one mixtures of being formed with arbitrary proportion;
(2) refinery coke, liquid medium and the additive with above-mentioned weight part grinds (the coke powder material that is ground in the slurry directly reaches 5-30 μ m) together according to conventional wet method (such as in ball mill), promptly; Or earlier the refinery coke dry grinding to be become particle diameter be the dried coke powder of 5-30 μ m, mixes and stirs into the oil coke slurry with liquid medium and additive again.
The using method of fuel-oil coking slurry of the present invention and the scope of application:, on Industrial Boiler, station boiler, Industrial Stoves, replace the oil gas use with being pumped to oil coke slurry burner and compressed air or steam atomizing afterfire after oil coke slurry of the present invention stirring, the filtration.
Fuel-oil coking slurry of the present invention is a component with refinery coke, liquid medium and additive.Refinery coke unit's calorific value is than coal height, and ash is again far below coal, thereby can be used in the occasion that requires low ash and replace oil (gas) burning.
Refinery coke is the final product in the petroleum refining process.Refinery coke is divided into common Jiao (retard petroleum coke), three kinds of high-quality Jiao's (needle coke) and extraordinary refinery cokes by working accuracy and burnt quality.The refinery coke of these three kinds of specifications all can be used as the raw material of fuel-oil coking slurry of the present invention.Common Jiao, promptly retard petroleum coke claims green coke, oil coke, refinery coke again.Retard petroleum coke is divided into 7 grades, i.e. 6 salable product such as first grade and 1A, 1B, 2A, 2B, 3A, 3B by quality.Refinery coke is black or dimmed harder solid, have metalluster, be porousness, be to form the charcoal body thing that granular, column or needle-like constitute by small graphite crystallization, main component is a carbon, about carbon containing 90～97%, hydrogeneous 1.5～8%, contain a spot of nitrogen, chlorine, sulphur and other metallic compound and dirt simultaneously.Common Jiao is used to make electrode, insulating material, silicon carbide and metallurgy industry fuel.The burnt main Graphite Electrodes of high-quality as steel-making superpower and ultra high power.Extraordinary Jiao is production reactor nuclear graphite sleeve pipe raw material.Make through the heating pyrolyze refinery by various Residual oils, pitch or heavy oil in the refining of petroleum.
Refinery coke product quality specifications and test method: meet SH0527-92.See Table 1.
The table 1 refinery coke specification of quality and test method
| Project | Quality index | Test method | ||||||
| First grade | Salable product | |||||||
| 1A | 1B | 2A | 2B | 3A | 3B | |||
| Sulphur content, % is not more than | 0.5 | 0.5 | 0.8 | 1.0 | 1.5 | 2.0 | 3.0 | GB/T387 |
| Volatile matter, % is not more than | 12 | 12 | 14 | 17 | 18 | 20 | SH/T0026 | |
| Ash content, % is not more than | 0.3 | 0.3 | 0.5 | 0.8 | 1.2 | SH/T0029 | ||
| Moisture is not more than | 3 | SH/T0032 | ||||||
| True density, g/cm 3 | 2.08～2.13 | Report | - | SH/T0033 | ||||
