Fluidized Carbonization of Coal

The internal heating fluidized carbonization process of fine coal, using air as fluidizing gas, has been described.The feature of this process is in obtaining semicoke not influenced by oxygen in spite of using air and in that the apparatus and its operation are very simple.Gas and tar have beer considered simply as fuel.The results of laboratory studies and of the operation of the fluidized carbonization furnace, the internal diameter of which is 200mm, have been explained.The uses of the semi-coke have also been discussed.As future development, it has heen stated that the production of town gas from fine coal by fluidized carbonization with the furnace both internally and externally heated is highly promising.
