Title: Method and apparatus for eliminating carbon
Inventor: HASHIMOTO SHIGERU
IPC: C10J3/72
Filed: 1992-12-15
Abstract: PURPOSE:To eliminate deposited carbon without allowing oxygen to flow into a thermal decomposition system in the process for thermally decomposing coal by supplying oxygen in the form of an intraoxide ion through an oxygen- permeable membrane. CONSTITUTION:Coal is quickly thermally decomposed by blowing it into a high-temp. gas flow in a quick thermal decomposition apparatus while eliminating deposited carbon by oxidizing it at 600-1,000 deg.C with oxygen supplied by an oxygen-contg. gas through an oxygen-permeable membrane. Thus, the oxygen- contg. gas introduced into between the inner and outer layers of the thermal decomposition system moves in the form of oxygen ion through the membrane to the inside of the inner layer where the decomposition is proceeding, thus allowing oxygen to react with the carbon without allowing an oxidant-supplying gas to come into direct contact with the air current of thermal decomposition.
