Latest Patents

Ryouji Takahira holds a patent for a "Method for regenerating filter and apparatus thereof." This invention involves a filter regeneration apparatus designed for a coal gasification system. The apparatus captures char, which is unburned matter present in exhaust gas. The method involves filling the filter container with inactive gas that has an oxygen concentration of less than 5 vol. % and heating the filter to a target temperature of 400 to 450°C. Additionally, ashing gas with an oxygen concentration of 5 to 15 vol. % is fed into the system, allowing for the safe ashing of char in the filter. This innovative method shortens the time required for filter regeneration by maintaining constant control over the oxygen concentration in the ashing gas and the filter temperature.
