Abstract

PROBLEM TO BE SOLVED: To provide a method for carbonizing wastes high in water content or viscosity, without causing problems involved in the conventional method, e.g. difficulty in supplying to or smoothly fluidizing them in the carbonization oven on account of high viscosity. SOLUTION: This method incorporates a carbide-containing material in wastes, e.g. starch residue, containing large quantities of water or high in viscosity, to absorb the water in the wastes by the carbide and thereby make them less viscous.

Means for Solving the Problems, Functions and Effects As a means for solving such problems, the invention of claim 1 reduces waste containing a large amount of water or containing highly viscous organic substances. In the method of carbonizing by heating and supplying in an atmosphere furnace, the material containing carbide is mixed with the waste, so the moisture in the waste is absorbed by the carbide and the moisture or viscosity of the waste decreases. And the fluidity of the waste in a supply apparatus and a carbonization furnace improves, and carbonization processing can be performed smoothly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As a comparative example, a high-moisture and highly viscous starchy waste containing 90% by weight of water was kept in a reducing atmosphere by a feeder having a screw conveyor connected to the lower part of a hopper. When placed in a carbonization furnace consisting of an externally heated rotary kiln and subjected to carbonization, solidification gradually accumulates on the outer cylinder of the screw conveyor and the screw stops due to an increase in the load on the screw,
Troubles such as solidification in the form of a bridge at the lower part of the hopper and not falling to the screw part frequently occur, and it is difficult to carry out the carbonization of the waste smoothly because the waste partially solidifies in the rotary kiln. Was.
