According to news from March 18, 2025, **information from the Intellectual Property Office shows that Tianjin Bohua Yongli Chemical Co., Ltd. has obtained a patent titled “A system for the catalytic hydrogenation treatment of butyl octanol,” with the approval number CN 222624489 U. The application was filed in April 2024.** The patent abstract indicates that this utility model discloses a system for the catalytic hydrogenation treatment of butyl octanol, which includes a butyl octanol catalytic hydrogenation reactor composed of an exhaust port cover, a tank body, and an inlet port cover. The exhaust port cover and the inlet port cover are connected to an exhaust gas main pipe and an aldehyde inlet main pipe, respectively. The interior of the tank body is divided into several cylinders with radial cross-sections in the shape of sectors; within each cylinder, there are hydrogenation reaction tube sets, catalyst reserve tube sets, and thermocouple tubes ； The outlet of each hydrogenation reactor tube bank is connected to the main exhaust pipe, while its inlet is connected to the aldehyde inlet pipe via an aldehyde branch pipe ； The outlet of each catalyst spare tube bank is connected to the main exhaust pipe, while the inlet is connected to the corresponding aldehyde branch pipe via a gas distribution pipe through a spare pipeline; a control valve for the spare pipeline is provided for each such spare pipeline. By modifying the butyl octyl alcohol catalytic hydrogenation reactor, this practical new design can eliminate hot spots and prevent as well as control the phenomenon of excessive temperature rise.
