Technical field
The invention belongs to field of fine chemical, more particularly to the slurries additive agent of a kind of phosphorous acid groups and its preparation side
Method.
Background technology
The main bugbear that current limitation COAL-WATER SLURRY TECHNOLOGY is promoted.It is primarily the specific demand in coal, is appropriate for slurrying
There are corresponding types to limit for the coal of operation, mainly in based on high deterioration coal.And the further expansion of the adjoint technology,
The demand of coal resources increases therewith, and middle high-order coal also faces the increasing pressure as main slurrying coal.China's coal
Low-order coal has rich reserves in charcoal resource, and advantage on the low side, western China is mainly based on low order coal, i.e.,
" three-lows ", " two is high ", the former represents low-sulfur, ash and phosphorus；The latter represents high volatile and calorific value, but the coal exists
The shortcomings of slurry concentration is relatively low, slurry poor performance provides technical barrier for slurrying, needs technical breakthrough, great development
Potentiality.The difference of coal, oxidation states, the hydrophobic performance of coal sample also have certain difference, and difference is made existing for coal characteristic
There is apparent difference at actual pulpability.Currently, in the research, exploitation of COAL-WATER SLURRY TECHNOLOGY, it can be by water coal
Modification, the compounding for starching additive, seek a kind of slurries additive agent that suitable low-order coal is slurried, to prepare high concentration, performance
Excellent water-coal-slurry, and product cost is low, has apparent price advantage.So China's slurrying at present is positioned at coal trend
Low-order coal.The industrial production of low-order coal slurrying is expanded, the sustainable development of industry and coal resources to COAL-WATER SLURRY TECHNOLOGY has
Important meaning.
One of core technology of COAL-WATER SLURRY TECHNOLOGY is slurries additive agent technology, and additive influences whether being slurried for water-coal-slurry
Performance and its production cost influence popularization and application and industrialization process of the COAL-WATER SLURRY TECHNOLOGY in China indirectly.
Therefore, existing market is badly in need of research, exploitation function admirable, and raw material sources are wide, cheap slurries additive agent,
The development for promoting China's COAL-WATER SLURRY TECHNOLOGY improves the efficiency of combustion of coal, realizes water-coal-slurry Produce on a large scale, reduces environmental pollution
While ensure the energy security in China.
