THERMAL DECOMPOSITION OF INFLAMMABLE WASTE MATERIAL

Title:

THERMAL DECOMPOSITION OF INFLAMMABLE WASTE MATERIAL

Document Type and Number:

Japanese Patent JP2001139962

Kind Code:

A

Abstract:

To provide a method for decomposing an inflammable waste material, capable of suppressing the generation of a tar component, enabling the stable operation of a thermal decomposition unit such as a fluidized bed type gasification furnace and also maintaining or improving the amount of heat generation of the thermally decomposed gas to reuse the energy of the waste material effectively in its thermally decomposition by bringing the inflammable waste material into contact with a heated powder fluidized medium.

This method for decomposing the inflammable waste material by bringing the inflammable waste material into contact with the powder fluidized medium, comprises performing the thermal decomposition by using a zeolite having 3.0-100 molar ratio of silica to alumina (SiO2/Al2O3) and 400-800 m2/l specific surface area as at least a part of it.
