Aqueous coal slurry composition
专利汇可以提供Aqueous coal slurry composition专利检索，专利查询，专利分析的服务。并且PURPOSE: To make it possible to stably maintain dispersing effect without generating a hard cake for a long period of time, by mixing a coal powder, water and a polyether compound shown by specific formula in a specific ratio.
CONSTITUTION: The titled composition is cnstituted from 0.5W80wt% coal powder, 20W99wt% water and 0.1W7.5wt% polyether compound shown by formula A[(C
3 H
6 O)
y (C
2 H
4 O)
z H]
x (wherein x is an integer of 2 or more, y and z are an integer of 1 or more, A is a residue formed through the removal of active hydrogen from an x valent active hydrogen compound. The wt. ratio of a polyoxypropylene chain and polyoxyethylene chain is 50/50W5/95 and M.W is 3,000W 100,000). The active hydrogen compound of the above mentioned polyether compound is an amino compound or a hydroxy compound and, for example, there is ethylenediamine or glycerine. By using the above mentioned aq. coal slurry composition, dispersing effect is stably maintained without generating a hard cake for a long period of time.
