Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an agent for improving the stability of a mixture of fine coke and oil having an average particle diameter of 200μ or more. However, there are difficulties in transportation, difficulty in controlling combustion,
It has drawbacks such as low calorific value and large space required for Irj storage, making it problematic as a fuel. A mixture of fine coke and oil does not have the above-mentioned drawbacks and has high practical value because it has a lower price per calorific value than oil alone.

However, simply mixing fine coke and oil does not yield a satisfactory fine coke oil mixture because the fine coke particles settle and separate due to the difference in specific gravity, coagulate, and lose fluidity.

Therefore, after extensive research to find an additive that would improve stability, we succeeded in finding an effective additive for a mixture of fine coke with an average particle size of 200μ or less, oil, and water. , made it possible to put it into practical use.

According to the present invention, even if stored for a long period of time at room temperature or high temperature, fine coke particles will hardly settle, and even if there is a slight amount of sedimentation, due to the excellent action of this agent, the settled fine coke particles will hardly aggregate. , it can be re-fluidized with only simple stirring. Of course, between class l11 (1
51El), there is no need for stirring. This has made it possible to safely transport the pulverized coke-six oil mixture by tanker over a long period of time, and to transport it through vibrate lines and piping.

The coke used in the fine coke-oil mixture means petroleum coke. Petroleum coke includes petroleum coke obtained as a by-product of pyrolysis and calcined petroleum coke obtained by calcination to increase the yield of light fractions of petroleum, but there are differences in type and production area. Any can be used, regardless of its chemical composition or moisture content. Further, the particle size of the fine coke is usually preferably 200 μm or less, and even smaller particle size of 10011 μm or less, judging from the combustibility. The content of this fine coke is 20 to 70% of the maximum mixture.
If the coke contains 70% or more of fine coke, the viscosity becomes extremely high and fluidity is lost, which is not preferable.

If it is less than 20%, the price of merino is low due to the inclusion of fine coke.

Therefore, the content can be 20 to 70%, but 30 to 6 Uzu.

Or even more preferred.

Also, what kind of oil is used in the fine powder Coke Suura mixture?

Petroleum crude oil, various fractions obtained from crude oil, such as kerosene, light oil, A heavy oil, B heavy oil, C heavy oil, etc. are the main products, and in addition, ethylene cracked residual oil, creoso 1-oil, Anne 1-herasene oil, various blended oils, etc. Oil and waste oil commonly used as fuel, such as gas station waste oil (automobile lubricating oil, cleaning oil),
Waste oil from ironworks (mixed oil of machine oil, cutting oil, cleaning oil, etc.), waste oil from oil tankers and other ships, waste oil from general chemical factories, etc., and also includes mixtures of these oils.

In terms of width, it is particularly preferable to use petroleum crude oil, 13 heavy oil, and C heavy oil.

Even if you make a fine coke-oil mixture using pre-blended oil, you can make a fine coke-oil mixture using a single oil (preferably petroleum crude oil or heavy oil) and then mix other d1 oils,
Mixed firing may be used.

It is better to add water to further improve the stability of the fine coke-oil mixture. Addition of water also has the effect of reducing NOx and vizine in exhaust gas during combustion. However, if more water is added, transportation costs, storage costs, and other general and administrative costs will increase depending on the volume of water, and the evaporation costs will also increase. Since it receives heat and increases heat loss, it is generally added in an amount of 1 to 30%, preferably 1 to 10%.

At least one compound selected from 0 to 100,000 acids of sulfonated, sulfuric acid esters, or phosphoric acid esters of polyether compounds, or salts of their counter ions.

Such machining for the fine coke-oil mixture of the present invention is as follows:
A stable fine coke-oil mixture can be obtained by simply adding 1% or more of coke and mixing. Is it natural that the effect will not worsen even if it is added to 1% or more?
For example, even if it is about 0.2%, the effect is remarkable, and there is no need to add more for economic reasons.

Also, 1. This essential component consisting of any one or more of items 1) to 9) may be used in combination with anionic, cationic, nonionic, or amphoteric surfactants, but the total amount of additives It must be present at least 5%, preferably at least 20%. Although the mechanism by which the agents of the present invention can exhibit outstanding effects when added in small amounts is unknown, it is likely that these agents are adsorbed onto the surface of coke particles in oil, and the repulsion and ion repulsion effects caused by the molecular chains of the agents are more than enough. It is believed that this function acts to prevent coke particles from coagulating and settling.

From this point of view, in order for the addition of small stars to exhibit the Kitaki effect, it is necessary to introduce a polar group for adsorption of the drug onto the surface of the coke particles, and to physically improve the coke particle surface. It is believed that a molecular size or bulk is required to prevent aggregation. The drugs of the present invention described in 1) to 9) all have such molecular structures. For example, the drug in 1) has a polar group based on a polyether group in the molecule and a molecular weight of 1,000 to 100,000. , preferably 3,0
The drug of 2) has a polar group based on an ether bond of alkylene oxide in one molecule, and has a molecular weight of i, ooo to IO, preferably 7,000 to 10,000. 10,000, and the number of active hydrogen atoms in the starting material of the polyether is 3 or more, preferably 5 or more.

The drug 3) also has a polar group based on the ether bond of alkylene oxide, has a large molecular weight of 1,000 to 1,000, preferably 7,000 to 10,000, and has two or more active hydrogen atoms as the starting material for the reaction. Since the number is preferably three or more, the molecule is characterized by being steric and bulky.

The major feature of the drug 4) is the remarkable stericity of the molecular structure based on the bond between the polar group based on the polyether group and the item-F nail polyether.

The drugs 5), 6), and 7) all have the same characteristics as the drug /l).

The drug 8) has a particularly polar ethylene oxy (ether) bond in one molecule, and has a molecular weight of 1,000 to 100,000, preferably 7,000-1 (
It is characterized by its large size of 10,000.

The drug of 9) has an extremely strong polar group based on a sulfone group, a sulfate ester group, or a phosphate ester group in its molecule in addition to a polar group based on a polyether group, and has a molecular weight of 1 or more and is bulky. A major feature is that

As described above, all of the agents of the present invention have polar groups, that is, parent groups, in their molecules, so when added to a fine coke-oil mixture, they adsorb to the surface of coke particles, which have weak hydrophilicity, and , because the molecules are large and bulky, when one particle approaches each other, due to steric hindrance of the molecules, 1
It is thought that it is extremely effective because it prevents particle agglomeration and sedimentation.

The agent of the present invention is effective either after being added to a mixture of fine coke and oil, or by adding the fine coke to a mixture of fine coke and oil in advance.

If the fine coke-oil mixture to which the agent of the present invention is added is stirred to uniformly dissolve or disperse the agent, a stable fine coke-oil mixture can be obtained. Although the stirring method is not particularly limited, if heating or strong stirring is applied at any point in the manufacturing process, the activity of the particle surface will increase and the adsorption of chemicals will improve, so fine coke powder - The performance of the oil mixture is further improved.

Strong stirring is usually 2 m/3 ec or more, preferably 10 m/3 ec or more.
It refers to adding a shear with a linear velocity of 2 m/sec or more, and stirring can be done using a propeller, Tahin type, screw type,
Any type of stirring, such as a line mixer, homogenizer, or colloid mill, may be used, and this strong stirring increases the activity of the coke particle surface and increases the chance of contact between the drug and the particle surface. In addition, heating should be carried out at 50°C or higher - 1-1 preferably 7 (
1'c or more is good.

Strong stirring or heating may be applied at any time, for example, when coke is crushed in oil, when a chemical is added after crushing, after the addition, during storage, or during pipe transportation.

This drug is effective even without heating or strong stirring, and when these conditions are added, the effect increases about twice as much.

Since this fine coke-oil mixture utilizes the additive of the present invention, there is almost no difference in performance between the upper layer and the lower layer, which can be used for more than 5 months at room temperature and for more than 90 days at 7υ°C. It is very stable, and even when burned in boilers or heating furnaces, it can be burned in a manner similar to ordinary liquid fuel.

Additionally, water when included in the present mixture exhibits positive effects such as improved flammability, reduced bysine, and reduced NOx. Rust inhibitors, anti-pollution agents, as necessary.
