DESCRIPTION:
BRIEF SUMMARY
This application is related to U.S. Ser. No. 07/576,486 filed Oct. 3, 1990.
FIELD OF THE INVENTION
The present invention relates to a method and an apparatus for refinement or treatment of material. More specifically, the present invention relates to converting processing, destruction, separation, disinfection, and neutralization of organic and inorganic materials, with or without organic and inorganic additions. The base material utilized is waste from other production, e.g. from the forest industry or slaughter-house waste, or material to be neutralized because of toxic or infective properties. The invention provides for refinement of the organic base material into directly useful or packeted end product where the base material is produced. The invention comprises carbonization of the base material into carbon powder, and subsequent treatment of the carbon powder into various forms. The invention specifically produces carbon powder/granulate as fuel, charcoal for grilling/smoking, active coal, additives for steel production etc and other substances derived in the separation process.
The invention also provides for treatment of inorganic material with the purpose of decomposing the material in order to neutralize poisonous or infective material and to recover the separated substances.
STATE OF THE ART
Various carbonization and charcoal burning methods have been known for a long time. The problem is to find a method which can be carried out to a lower cost, since the base material often has a very short range of action, i.e., it is not worthwhile to transport the base material a longer distance than e.g. 50 km. On the other hand, coal from coal mines is contaminated by sulphides and thus requires expensive purification by filters etc.
The present invention provides a dynamic system which can be transported to the origin of the base material and which at low cost refines or processes the material. Thus, organic materials, such as agricultural, forest and slaughterhouse waste, can be used, which materials are not contaminated by undesired substances. Also, inorganic materials can be processed by the system of the invention, with the purpose of neutralization, disinfection etc.
SUMMARY OF THE INVENTION
Accordingly, the present invention provides a method of processing of material characterized by the steps of:
feeding finely divided base material of into a closed reactor;
decomposing the base material into a solid phase and reaction fluids by heat treatment in said reactor;
cooling the separated solid phase; and
if necessary, forming the solid phase to the desired particle size.
Advantageously the cooling step further includes additional treatment of solid material, such as mixing with organic and/or inorganic materials in order to produce various end products. The invention is especially intended for producing charcoal for grilling/smoking, active coal and carbon powder/granulate as fuel.
The invention also provides an apparatus for carrying out the method of the invention.
