Latest Patents

Toshiaki Okuhara holds a patent for a "Process for producing formed coke for metallurgical use." This process involves producing formed coke from coal powder by continuously heating it with a high-temperature gas. The method includes carbonizing agglomerated coal made from coal powder and a binder, such as coal tar, pitch, and petroleum asphalt. The process features the introduction of tuyeres for gas at the middle and lower parts of an upright carbonization oven. The temperature of the gas supplied to the tuyere at the middle part is adjusted to between 600°C to 800°C, while the supply rate of the gas is controlled to maintain the temperature of the gas on the agglomerated coal at 300°C to 500°C. Additionally, the supplied heat to the lower part of the carbonization oven is adjusted to be less than 50% of the total supplied heat.
