Catalyst Evaluation Reactor Device - Beijing

principle
Wuzhou DingchuangCatalyst Evaluation Reactor Device - BeijingFixed bed reactor, also known as packed bed reactor, is a type of reactor that is filled with solid catalyst or solid reactants to achieve multiphase reaction processes. Solid materials are usually in granular form, with a particle size of about 2-15mm, stacked into a high (or thick) bed layer. The bed remains stationary, and the fluid reacts through the bed. The difference between it and fluidized bed reactors and moving bed reactors is that the solid particles are in a stationary state. Fixed bed reactors are mainly used to achieve gas-solid phase catalytic reactions, such as ammonia synthesis towers, sulfur dioxide contact oxidizers, hydrocarbon steam reforming furnaces, etc. When used for gas-solid or liquid-solid phase non catalytic reactions, the bed is filled with solid reactants. A trickle bed reactor can be classified as a fixed bed reactor, where gas and liquid phases flow downward through the bed layer in a gas-liquid solid phase contact.
The fixed bed micro reactor experimental device is an automated micro experimental device controlled by a programmable controller and computer. The device operates automatically, and the temperature, flow rate, pressure signals, and detector signals at each operating point are automatically collected by the system, and the real-time changes in various parameters during the reaction process are displayed through the computer. By setting temperature and flow values through the computer system, users can achieve automated operation of the device. The reaction pressure of the device can be adjusted manually or automatically using a back pressure valve according to different requirements.
The advantages of a fixed bed reactor are: ① small backmixing, effective contact between the fluid and catalyst, and high selectivity when the reaction is accompanied by series side reactions. ② The catalyst has minimal mechanical wear and tear. ③ The structure is simple and includes oil or molten salt heat exchange reactors, computer linked data acquisition and temperature control software, online sampling six way valves, various types of liquid feeding pumps, and gas chromatographs for users to choose from when ordering. In addition, design and processing can be carried out according to user requirements.

brief introduction
It is an automated system used for evaluating catalysts under high temperature, high pressure, or high temperature and atmospheric pressure.
