Description
Technical field
The present invention relates to the preparation method of a kind of degradable biological base dispersant, belong to dispersant preparing technical field.
Background technology
China is a country for the few oil of rich coal, and coal resources account for more than 65% in China's energy-consuming.Traditional user
The shortcomings such as method has that lime-ash is many, pollute big, transport difficult and combustion heating rate is the highest, COAL-WATER SLURRY TECHNOLOGY is then for these shortcomings
Coal resources are carried out the major reform of deep processing, Appropriate application.Water-coal-slurry is that a kind of employing physical method is by coal liquefied
New-type fuel, the coal being made up of certain particle size, water and a small amount of additive are prepared from.It had both maintained the original thing of coal
Reason feature, has again the same mobility of image-stone oil and stability, is referred to as liquid coal product.Slurrying additive mainly has
Dispersant, stabilizer and other assistant medicaments, wherein dispersant plays a crucial role.Dispersant is that one has in intramolecular simultaneously
Lipophile and the interfacial agent of two kinds of opposite nature of hydrophilic.Can homogeneous dispersion those be poorly soluble in liquid inorganic, have
The solid of machine pigment and liquid particles, also can prevent sedimentation and the cohesion of granule simultaneously, forms the amphiphilic needed for stable suspension
Property reagent.At present, the coal water slurry dispersing agent of commercial Application mainly has naphthalene system, humic acid, Lignins and relevant compounding product
Product.Although naphthalene system dispersant low price, good dispersion, the glutinous effect of fall is strong, but slurry poor stability, easy bleed produces hard-caked sediment.
Lignosulfonates poor-performing, general and other dispersants are compounding to be used, the most degradable.Then there is system in humic acid system dispersant
The slurry problem that viscosity is big, dosage is many, though and other non-ionic dispersing agents are efficient but expensive, slurrying cost height.
Summary of the invention
