Description
Technical field
The present invention relates to the coal water slurry field, particularly a kind of negatively charged ion-nonionic Compositional type gasification slurries additive agent.
Background technology
Coal water slurry is one of clean coal technology that last century, the eighties was risen.It is coal, water and a small amount of formulated a kind of slurry of chemical additive that is distributed by certain particle size.It has the same flowability of oil, can pumping, atomizing and fire burns, can substitute oil as boiler fuel, also can be used as gasification raw material preparing synthetic gas, processing downstream Chemicals.
Water coal slurry replacing oil and coal water slurry gasification have obtained widespread use in China over past ten years, and especially coal water slurry is developing faster as the gasification raw material, and existing nearly ten coal water slurry gasifications are runed factory, nearly ten million ton of year slurrying amount.Present rise along with coal resources in China anxiety and coal price, many coal water slurry gasification raw materials adopt or have allocated into the difficult sludge forming performance coal of relative low price, but because interior water-content height, hole prosperity, that oxygen-containing functional group enriches metamorphic grade is low, the coal-water fluid concentration of operation is only about 60%.Many coal water slurry gasifications enterprise needs the coal-water fluid concentration that improves low rank coal badly.
Coal water slurry product requirement with industrial application value has characteristics such as high density, low-viscosity, good flowability and steady time is long.In the coal water slurry production process, slurries additive agent plays crucial effects to the coal water slurry performance.Slurries additive agent mainly contains dispersion agent, stablizer and other assistant medicaments, and wherein dispersion agent plays a key effect.At present, coal water slurry dispersing agent mainly contains Lignins, naphthalene system, humic acid and non-ionic type etc.But these products respectively have advantage, also each defectiveness, and application facet is restricted to some extent.Advantage as sulfonated lignin is an abundant raw material, low price, and stability is better, but shortcoming is that the slurrying viscosity is bigger, slurry is mobile bad; Naphthalene is that dispersion agent good dispersity, viscosity reduction effect are strong, the slurry good fluidity, but slurry stability is relatively poor, and bleed produces hard-caked sediment easily; The major advantage of non-ionic dispersing agent is that the amphipathic property of molecule and relative molecular mass are easy to regulate and control, is not subjected to the influence of solvend in water quality and the coal, need not add stablizer, but cost an arm and a leg.
Because slurries additive agent molecular structure and ature of coal exist matching, this matching affects sludge forming performance, rheological and the slurry stability of coal.The universality of slurries additive agent is limited, and several additives can not be pervasive in all coals.Studies show that at present anionic dispersing agent and non-ionic dispersing agent composite not only has more good effects on slurry making, that lacks when the total consumption of dispersion agent is than the corresponding dispersion agent of independent use simultaneously is many.This shows that the composite of dispersion agent not only can be improved water coal slurry concentration, reduce viscosity of coal slurry, can also reduce the consumption of total additive simultaneously, reach inexpensive, purpose efficiently.
The invention provides a kind of negatively charged ion-nonionic Compositional type gasification slurries additive agent, be by anionic dispersing agent sulfonated lignin, naphthalene sulfonic acidformaldehyde condensation product, non-ionic dispersing agent oxyethane and propylene oxide block copolymer, hole-blocking agent, acid-base modifier is composite by a certain percentage forms.It has the wide characteristics of suitable coal scope, and especially internally water-content height, hole prosperity, oxygen-containing functional group enrich the low coal water slurry gasification coal of metamorphic grade, have improved the sludge forming performance and the concentration of coal for gasification.
