Latest Patents

Uehara holds a patent for a process for heat treatment of coal. This process involves rapidly heating highly hygroscopic coal, which has a low carbon content and large equilibrium moisture. The coal is heated with hot gas at a rate of temperature rise of at least 100°C per minute, reaching a final heating temperature between 300°C and 500°C. Following this, the coal is rapidly cooled at a rate of temperature drop of at least 50°C per minute to 250°C or below. The hot gas used in this process is an inert gas with an oxygen concentration not exceeding 4% by volume. Additionally, the hot gas may contain at least 20% by volume of steam or consist solely of steam.
