Application summary of C306 type catalyst in 100kt/a methanol plant

C306 type catalyst for synthesis of methanol at lower pressure should be sieved by griddle before filled into column in order to remove the powder. Middle sized fireproof aluminum ball is used to ensure the applying strength. The pipes are loaded with 20.15 m~(3) C306 type catalyst, of which 2.13 m~(3) catalyst is loaded in adiabatic layer. After the system is replaced and qualified to the request, temperature reduction of the catalyst can be carried out by means of low hydrogen method and the reduction rate can be controlled by reductive dewatering rate. The application results show that the catalyst has advantages of high mechanic strength, excellent flexibility, convenient reduction and simple operation, good activity at low temperature, wide temperature range, stable performance, and better selectivity. The content of impurities in coarse methanol low, and the reductive shrinkage of the catalyst is small, therefore the effective space of the methanol synthesis column is exerted sufficiently.
