Introduction: The laboratory catalytic cracking device is an effective means for determining petroleum hydrocarbons or other organic compounds in the presence of a catalyst, and can find the optimum operating conditions of the catalyst according to the experimental results, improve the performance of the catalyst or test the life of the catalyst. Provide reliable reference data for industrial operations while providing the necessary parameters for amplification. The device is an empty tube, and the internal thermocouple sleeve is provided with a catalyst support frame, and the thermocouple can be moved in the reaction, and the temperature at any position in the bed can be measured. The device has a simple structure and a compact process, and can replace different tube diameter reactors. The reaction operation is flexible and the performance is reliable. In addition, other solid catalysts may be charged as needed to carry out a gas-solid phase catalytic reaction. After the cracking reaction, the catalyst may be carbonized to cause a decrease in activity, and the carbon is regenerated by air to recover the activity. It is one of the necessary equipment for teaching, scientific research and industrial design. The device can be combined according to the user's use requirements, such as: the raw materials are gas, liquid, gas-liquid mixture, the feeding mode can be entered from the upper part of the reaction tube (general process), or can enter from the lower part of the reaction tube (special process), different The material mode is also different in the installation position of the condenser, and the position of each interface can be conveniently changed during use to achieve the required operation mode. The teaching experiment uses a common feeding process and cannot change the feeding position.
