Description
Technical field
The present invention relates to coal gasification commercial Application, in particular to a kind of cheap, efficient, cost-effective Compositional type
Slurries additive agent.
Background technology
China is the country of the rich few oil of coal, and rich coal resources account for about the 70% of domestic energy consumption.The biography of coal
Application method lime-ash of uniting is more, pollution is big, transport difficult and expensive, burning and heating efficiency be not high.Water-coal-slurry is a kind of use
The environmental clean fuel of New type coal base flow body and a kind of coal prepared by physical method does the novel original of raw material production synthesis gas
Material.The technology passes through to coal resources deep processing, rationally using improving the utilization rate of coal resources.
In water-coal-slurry raw material production cost, other than 60%~70% coal and 30%~40% water, water-coal-slurry is improved
The slurries additive agent of performance constitutes the second largest cost factor of water-coal-slurry.Slurries additive agent is to the viscosity of water-coal-slurry, dense
The key indexes such as degree, stability and mobility suffer from directly influencing, so, reduce the use of slurries additive agent into
This, improving effective utilization becomes a key subject of current COAL-WATER SLURRY TECHNOLOGY.
At present, domestic and international slurries additive agent is broadly divided into two major class of anionic and neutral ionic.By its chemical group
Into difference, be divided into for：Naphthalenesulfonate formaldehyde condensation compound, lignosulfonates, humate, polycarboxylic acids, polyolefin, aliphatic poly
Close object, polyethers and long-chain alcohol ketone derivatives etc..
Different slurries additive agents disperses viscosity reduction ability, slurry concentration, mobility and stability to same coal
Effect is different.All in all, anionic slurries additive agent-naphthalenesulfonate formaldehyde condensation compound that the country largely uses at present
Its dispersion performance, slurry mobility are preferable, applied widely, however slurry stability is poor, and due to producing naphthalene sulfonate
The higher price of raw material-naphthalene of formaldehyde condensation products, the cost price for leading to naphthalenesulfonate formaldehyde condensation compound is higher, a large amount of to use
Cause production cost higher so that the slurries additive agent competitiveness of naphthalenesulfonate formaldehyde condensation compound class declines.Lignin sulfonic acid
For salt compared with naphthalenesulfonate formaldehyde condensation compound, price advantage is apparent, and raw material resources are enriched and are easy to get, and slurrying stability compared with
It is good.But the complicated component and performance due to the lignin as raw materials for production are unstable, lignosulfonates it is slurry
Performance is also unstable, it is difficult to meet commercial Application requirement.Humate is extracted from low price coal, and dispersion performance is preferable, but
It easily forms precipitation, the stability of slurry is very poor to metal ion-sensitive.Polycarboxylic acids, aliphatic polymer, gathers polyolefin
Ethers and long-chain alcohol ketone derivatives are according to the difference of its molecular weight, and using effect is different, and all in all, effect is better than
Naphthalenesulfonate formaldehyde condensation compound, lignosulfonates and humate, but due to strictly to control molecular weight and at high price,
It cannot be widely used to promote.
China's slurries additive agent type currently in use is various at present, and quality is irregular, cost performance it is not high or
Efficiently at high price or cheap performance is bad, it is difficult to meet increasingly competitive industrialization development.In addition, with environmental protection
Pressure increases, often with the buck of gasification system, steam condensate (SC), other process units during coal water slurry gasifying device slurrying
It produces one or more of waste water, biochemical water, alkali waste water etc. and partly or entirely replaces technique desalted water, considerably increase water coal
The slurrying difficulty of slurry.The slurries additive agent of single use a certain kind component can not meet the development of coal water slurry gasifying device
It is required that therefore, we must develop a kind of higher high ecad Compositional type slurries additive agent of sexual valence, to cope with water-coal-slurry
The increasingly complicated operating mode of gasification installation pulping system, improves water coal slurry concentration, reduces viscosity of coal slurry, improve water-coal-slurry mobility,
Expand gasification slurrying coal range.
