The Shaanxi Coal-Based Special Fuels Research Institute has obtained a patent for a modular, multi-functional coal pyrolysis device, which enhances the flexibility of such experimental setups as well as the stability of their operation. According to information from the Intellectual Property Office, dated August 26, 2025, the Shaanxi Coal-Based Special Fuels Research Institute Co., Ltd. has been granted a patent titled “A Modular, Multi-Functional Coal Pyrolysis Device”; the approval number is CN223268577U, with the application date being September 2024. The patent abstract indicates that this utility model discloses a modular multi-functional coal pyrolysis device, which includes a gas module, a gas activation module, a pyrolysis module, a catalytic module, and a reception module. The gas module includes gas pipelines and reactor heads ； The gas activation module includes a heating furnace and Reactor No. 1 ； The pyrolysis module includes a heating furnace, Reactor No. 2, a reactor head, and a cooling coil ； The catalytic module includes a heating furnace and Reactor No. 3 ； The receiving module includes a refrigerator, a coal tar cooler, a coal tar collector, and a pyrolysis dry gas transmission pipe. Compared with existing technologies, it enables the conduct of various types of coal powder pyrolysis experiments on the same setup, such as those involving the coupling of gas activation with coal powder pyrolysis, gas activation with catalytic coal powder pyrolysis, gas activation with rapid coal powder pyrolysis, and gas activation with catalytic rapid coal powder pyrolysis. This improves the flexibility of the coal pyrolysis experiment apparatus as well as the stability of its operation, thereby increasing the conversion rate of coal powder and addressing the issue of difficulty in separating semi-coke from the catalyst.
