Abstract: The present disclosure relates to the technical field of catalysts, and specifically to a Zn—Al slurry catalyst, its preparation method and its application in preparing ethanol from syngas. The preparation method provided in the disclosure prepares the Zn—Al slurry catalyst by introducing a zinc component into an aluminum sol, and the preparation method has a simple operation and a lower cost. The Zn—Al slurry catalyst prepared in the disclosure includes the Zn component and the Al component, which may catalyze syngas to generate ethanol under mild conditions. Also, the catalyst has stable properties, is not easy to be deactivated, and reduces the cost of preparing ethanol from syngas. When the Zn—Al slurry catalyst provided in the disclosure is used as the catalyst for preparing ethanol from syngas, the reaction conditions are mild, and the syngas may be catalyzed to generate ethanol under the conditions of 250-340° C. and 3-5 MPa.

Abstract: Provided is an electromechanical-linkage hydraulic control gate valve actuator. The actuator includes a hand-operated speed-increasing gearbox assembly and a bidirectional throttle valve. In the present invention, a motor is driven to rotate through the hand-operated speed-increasing gearbox and thus a hydraulic system is driven to finally open and close a gate valve. An opening and closing speeds of the gate valve can be regulated and controlled through the bidirectional throttle valve. The present invention drives the motor through the hand-operated speed-increasing gearbox under emergency conditions such as repair and power failure, thereby controlling to open and close the gate valve. Meanwhile, a hydraulic system respectively regulates the speeds of two states of opening and closing through a bidirectional throttling technique, so as to effectively eliminate a water hammer phenomenon. The present invention has simple structure, light weight and modular installation, and enhances safety and reliability.
