Operating conditions:

● Normal Operating Conditions:

Temperature: 190℃~300℃，the best use range is 210℃~270℃

Pressure: 4.0 ~ 10.0 MPa

Airspeed: 4000-20000 h-1

● Use Precautions:

When necessary, perform sieving prior to tower loading to ensure uniform packing, and take precautions to prevent contamination, particle breakage, and moisture exposure. The internal vibration method may be employed during the process.

The copper based methanol synthesis catalyst reduction process is an exothermic reaction. It is recommended to adopt low-hydrogen reduction during temperature elevation, with the key being to control the reduction rate. The rate of reduction is determined by the reduction temperature and is closely related to hydrogen concentration, while also being influenced to some extent by pressure and space velocity. The reduction process requires steady temperature increases and uniform water discharge.

For shell-and-tube reactors cooled by boiling water, the critical aspect of reduction operation lies in controlling the H₂ concentration in the reducing gas to prevent sudden temperature spikes or excessive water discharge, as these could compromise the copper based methanol synthesis catalyst's activity, mechanical strength, and lifespan. The reduction process should adhere to the principle of "increasing hydrogen without raising temperature, and raising temperature without increasing hydrogen." This ensures stable temperature elevation, controlled hydrogen replenishment, and consistent water discharge throughout the procedure.

The thermal conductivity of copper based methanol synthesis catalyst itself is poor, and large temperature fluctuations will cause local overheating of catalyst bed. Long-term operation at high temperature will accelerate the growth of active copper grains, the gradual loss of active surface, and accelerate the "aging" of catalyst. To ensure copper based methanol synthesis catalyst smooth operation, try to use at low temperatures.

During the operation process, especially starting and stopping, pay attention to the pressure raising and lowering not too fast to prevent the copper based methanol synthesis catalyst crushing.

Reduce sulfur, chlorine, oil and other impurities in the raw gas as much as possible, and control the total sulfur below 0.1ppm.
