Microreactor deviceProduct Overview

Both microreactors and reactors can be divided into tubular reactors or kettle reactors. Microreactors are suitable for rapid selection of catalyst components, and can even complete the screening of a catalyst within ten minutes to determine whether it is necessary to continue research on a catalyst. At the same time, after screening multiple catalysts, the better catalysts can be further evaluated, usually done in a stack reactor, which can greatly save time in researching and developing new catalysts.

Microreactor deviceProcess: This device is equipped with four gas paths for feeding.

1. Gas path process: The high-pressure reaction gas from the steel cylinder or pipeline enters the filter after being dried and removed from the tank, to filter out possible small solid particles in the gas, and then enters the gas pressure regulator valve. The function of this pressure regulator valve is to stabilize the pressure at the gas inlet of the mass flowmeter, especially when the gas usage is relatively large, the gas source pressure may change significantly, and the pressure behind the valve can be read by a pressure gauge. And by setting the value of the flow meter, the flow rate of the flowmeter can be controlled, and the true value of the flow rate can be read from the instrument. However, it should be noted that this reading refers to the volume of the gas under standard conditions, not the volume flow rate at the current temperature and pressure, and needs to be converted according to standard conditions. If it is not air or nitrogen, it should also be calibrated according to the flow coefficient in the gas meter at the end of the flowmeter manual. There are short circuit valves for charging before and after the mass flow meter. When the reaction begins, in order to quickly complete the boosting process, this valve can be used to rapidly charge the reactor. It can also be used for cleaning or blowing at the end or beginning of the reaction.

The upper and lower structures of the reactor are simple, and the sealing head is easy to operate. The sealing nut can be tightened directly. In order to accurately control the reaction temperature, there is a temperature sensor on the outer wall of the reactor. At the same time, in order to accurately measure the temperature inside the reactor, investigate whether the reaction is constant temperature, and determine the axial temperature distribution of the catalyst bed, there is a thermocouple inside the reactor that can move freely. There is an outlet at the bottom of the reactor, and the gas at the outlet of the reactor enters the gas-liquid separator after being cooled by a straight condenser. The reaction furnace is a specially designed large heat capacity open heating furnace, which is heated in sections and the temperature can be set arbitrarily. The special heating method ensures that the length of the constant temperature zone inside the furnace is superior to other heating forms, and can maintain temperature stability in strong reaction heat environments, suitable for various reaction occasions. The heating furnace is lined with an alloy lining, ensuring a constant temperature effect.
