CO Low Temperature Shift Catalyst,

1.General

BL-03CO Low Temperature Shift Catalyst is a kind of Cu-Zn-Al based product prepared with the advanced process. It is most suitable for CO shift process in synthetic ammonia or hydrogen plants under the condition of low steam/gas ratio.

Catalyst BL-03 is a kind of energy-saving catalyst produced by using international state-of-art technology. Catalyst BL-03 has the characteristics as low temperature, high activity, low bulk density and high operating strength after reduction as well as suitable to be used under low steam/gas ratio process condition. The perfect feature of the catalyst BL-03 is the high selectivity, which can inhibit alcohol forming efficiently. It is used in the down steam of the high temperature shift catalyst to further shift the CO in rich hydrogen flow and to produce more hydrogen through the following reaction:

CO+H2O=CO2+H2+41.9KJ/mol

And purify the hydrogen simultaneously.

Catalyst BL-03 can inhibit properly the following side reaction caused by decreasing the steam/gas ratio:

nCO+2nH2=CnH2n+1OH+(n-1)H2O+H

2CO=CO2+C+H

There is no free water in BL-03 finished product, so there is no need to remove water in the course of warming up reduction.
