Feed charcoal, water and a bubble stabilizer to a wet pulverizer, and prepare a highly concentrated slurry with a coal concentration of 65 to 95% by weight containing bubbles made of O 2 gas or gas containing O 2 gas while pulverizing; By supplying this highly concentrated slurry to the gasifier, it is possible to increase the gasification rate in the gasifier and provide a stable supply to the pressurized reaction system, which eliminates the need to evaporate large amounts of water as with conventional slurry. The purpose of the present invention is to provide a method that can gasify coal with high gasification efficiency without any gasification.

The drawing shows an example of a device for carrying out the method of the invention. Raw coal (which may be either coking coal or non-caking coal) is crushed in advance to approximately 10 mm or less, and then supplied to a wet crusher 1 (for example, a ball mill).
At the same time, water and a bubble stabilizer are added, and the raw coal is pulverized in the wet pulverizer 1 while blowing O 2 gas or a gas containing O 2 gas,
Thoroughly mix the pulverized coal, water and foam stabilizer. The amount of foam stabilizer added at this time is 0.01 to 3% by weight relative to the coal, preferably 0.3 to 1.5% by weight, and the concentration of the slurry (coal content) is 65 to 95% by weight on a dry basis. . There are mainly two types of gasifiers, such as spouted bed type and fluidized bed type.For spouted bed type, the smaller the particle size of the coal, for example, the 200 mesh passing rate is about 10 to 80%. It is more suitable if the particle size of the coal is larger, for example, it is crushed to 2 mm or less, and the viscosity is lower in both cases.
It is about 300 to 3000 cp.

By preparing a highly concentrated slurry, it is possible to obtain a highly concentrated slurry containing bubbles made of O 2 gas or a gas containing O 2 gas. When this slurry is supplied to a gasifier, it is well dispersed because it contains bubbles, and the O 2 concentration near the coal particles increases because the bubbles are composed of O 2 gas or gas containing O 2 gas. It increases the gasification rate in the gasifier and improves the gasification efficiency. Bubbles in the slurry are generated by entraining atmospheric gas in the wet grinder and are stabilized by a bubble stabilizer. For this reason, it is desirable to use a bubble stabilizer that has a dispersing effect.
