Hebei Xuyang Energy and others have obtained a patent for a device used in the regeneration of titanium-silica molecular sieve catalysts that become deactivated due to olefin epoxidation. According to information from the Intellectual Property Office, Hebei Xuyang Energy Co., Ltd. and Dingzhou Xuyang Technology Co., Ltd. have been granted a patent titled “Device for the Regeneration of Titanium-Silica Molecular Sieve Catalysts Deactivated by Olefin Epoxidation”; the approval number is CN223170934U, with the application date being September 2024. The patent abstract indicates that this utility model discloses a regeneration device for titanium-silica molecular sieve catalysts that become deactivated during the epoxidation of olefins. It includes a methanol distillation tower, a methanol reboiler, a methanol cooler, a catalyst acidification tank, a methanol reflux pump, a methanol feed pump, a fresh methanol storage tank, a bag filter, and an acid solution storage tank. The methanol distillation tower is connected to the methanol cooler; the methanol reboiler is connected to the methanol distillation tower. The methanol cooler is connected to the catalyst acidification tank via pipes, while the catalyst acidification tank is connected to the methanol reflux pump via pipes. The methanol reflux pump is in turn connected to the methanol distillation tower via pipes. The fresh methanol storage tank is connected to the methanol feed pump via pipes, and the methanol feed pump is connected to both the catalyst acidification tank and the methanol distillation tower via pipes. The catalyst acidification tank is connected to the bag filter via pipes, and the bag filter is connected to the fresh methanol storage tank via pipes. The bottom of the methanol distillation tower is connected to the acid solution storage tank via pipes.
