Device for testing dehydrogenation performance

The invention belongs to the field of chemical engineering, particularly relates to a catalyst performance test device, and provides a device for testing dehydrogenation performance. The device adopts a three-section tank body structure connected through flanges (17), and comprises a box body, a gas inlet pipeline (15), a gas disperser (4), a water replenishing port, a water outlet (11), a flow valve A (12), a flow valve B (13), a catalyst dehydrogenation device (3), a shunting pipeline (16), a gas discharge pipeline (5) and peripheral testing instruments, wherein the box body comprises an upper sealing head, a tank body and a lower sealing head; a spiral fan blade is arranged on the inner wall of the gas inlet pipeline (15); mixed gas enters the box body through the gas inlet pipeline (15), reacts in the catalyst dehydrogenation device (3), and is discharged from the gas discharge pipeline (5); the testing instruments are connected to the temperature measuring point, the pressure measuring point and the concentration measuring point of the box body respectively, so as to monitor an experiment in a real-time manner, control the experiment process, and test the performance of the catalyst dehydrogenation device (3).
