Title:
PREPARATION OF COAL DISPERSION FUEL
Document Type and Number:
Japanese Patent JPS5456609
Kind Code:
A
Abstract:

PURPOSE: To prepare a large amount of stable dispersion fuel continuously in a short time, by dispersing a mixture of coal powder, a hydrocarbon oil and a surface active agent, with a line mixer wherein the gap between the stator and the turbine is adjusted in a specific range.

CONSTITUTION: A mixture of (A) coal powder, (B) a hydrocarbon oil such as heavy oil, crude oil, etc., and (C) a surface active agent, is homogenized by a line mixer having a gap between the stator and the turbine of 0.1-5.0mm, pref. 0.3- 1.0mm, and an rpm of the turbine of 500-15000, pref. 2000-5000, thereby obtaining a dispersed oil. The surface active agent is perf. an ionic surface active agent, esp. the one having a sulfonic acid group or a sulfuric acid group in the molecule, or a phosphoric acid ester, a salt of higher fatty acid, etc. The amounts of the components are pref. 40-70% of coal powder and 30-60% of the hydrocarbon oil, and 0.01-5%, pref. 0.1-2%, based on (A)+(B), of the surface active agent
