    摘要: Disclosed are an apparatus and method for preparing alcohol from olefin. A reactor for hydroformylating olefin comprises a loop reactor for reducing high-boiling point components, a post-treatment device for separating aldehyde comprises a catalyst/aldehyde separator and a divided wall column (DWC) for removing remaining high-boiling point components, and a post-treatment device for separating alcohol comprises a divided wall column (DWC) for removing remaining high-boiling point components. The apparatus and method for preparing alcohol reduce production of high-boiling point components in the preparation of alcohols and efficiently remove remaining high-boiling point components, thus obtaining alcohol containing no high-boiling point components.

    摘要: Disclosed is a method for regenerating a hydrogenation catalyst. More specifically, disclosed is a method for regenerating a hydrogenation catalyst poisoned during hydrogenation of a hydroformylation product for preparation of alcohol by stopping hydrogenation in a hydrogenation stationary phase reactor in which the hydrogenation catalyst is set and flowing hydrogen gas under a high temperature normal pressure. The method has an effect in that the poisoned hydrogenation catalyst can be efficiently recovered through a simple process.
