Regarding the service life of methanation catalysts
Thread Content
Our company has been using methaneation catalysts for 10 years now; we’re not sure whether we can continue to use them. We would like to consult manufacturers that use methaneation catalysts.
Ten years? This can be determined by checking whether the hot spots in the bed temperature of the methanation reactor shift to lower positions, as well as by examining the pressure difference in the methanation reactor. Of course, there are many devices available for evaluating the performance of catalysts, but these require hiring professionals to use them.
Reply to 1# chenglaibing: It has been in use for ten years and performs quite well. Whether to replace it depends on whether the activity of the current methanation catalyst is sufficient to ensure the normal operation of the facility. It can be determined through parameters such as hotspot temperature, temperature difference, and outlet gas composition. If the catalyst is in an advanced stage, it is recommended to replace it to ensure safe operation under subsequent operating conditions@
Reply to 3# Huang Xinhui: I hope the manufacturers that are using methanation catalysts can offer me some help!
We also use methanation. The reason for replacing the catalyst is based on its activity; ensuring that the output levels remain within acceptable limits over a long period is not a factor in determining when to replace it. What matters is whether the catalyst has reached the end of its useful life – in that case, replacement is necessary
