Abstract
Description
Изобретение относитс к водной дисперсии угл , которую можно ис- пользовать дл получени жидких и газообразных продуктов и дл производства электроэнергии и тепла.The invention relates to an aqueous dispersion of coal that can be used to produce liquid and gaseous products and to produce electricity and heat.
Цель изобретени - повьшгение стойкости к флокул ции и оседанию и улучшение реологических свойств дисперсии угл .The purpose of the invention is to improve flocculation and sedimentation resistance and improve the rheological properties of coal dispersion.
Водную дисперсию угл приготовл ют путем смешивани лецитина в виде водной эмульсии или раствора в органическом растворителе с порошковым углем в воде с последующим добавлением полимера. Органический растворитель можно удал ть из полученной таким образом дисперсии.The aqueous carbon dispersion is prepared by mixing the lecithin in the form of an aqueous emulsion or solution in an organic solvent with powdered coal in water, followed by the addition of a polymer. The organic solvent can be removed from the dispersion thus obtained.
Пример 1. Описанным образом приготовл ют водную дисперсию угл , содержащую, мас.%: порошковый уголь 65, лецитин,примен емый в виде водной эмульсии 0,05; сополимер 0,5, полиэтиленоксид 70, подипропиленок- сид, имeюD ий мол.м. 14000 30, вода 34,45.Example 1. In this way, an aqueous dispersion of coal is prepared, containing, in wt%: powdered coal 65, lecithin, used in the form of an aqueous emulsion 0.05; copolymer 0.5, polyethylene oxide 70, pipropylene oxide, having the molon mol.m. 14000 30, water 34.45.

Дисперси согласно а и S стабильна к флокул ции , а ее стабильность к оседанию 6 и 8 нед. соответственно.Example 2. Example 1 is repeated with the difference that 60% by weight of powdered coal is mixed with 0.5% by weight of lecithin and from a) 0.1% by weight of naphthyl polyethylene oxide mol.m. 5000 and S) 3 sat.% | 5-naphtsh1 polyethylene oxide mol.m. 5000. In the case of a) the water content in the resulting dispersion is 39.4 wt.%, And in the case of S) it is 36.5 May. In case a) the viscosity of the water dispersion is 208 cP, and in the case of Sj 296 cP. The dispersion according to a and S is stable to flocculation, and its stability to sedimentation is 6 and 8 weeks. respectively.
