Description
Model：B**8
Features：
1. Low bulk shrinkage
rate
The bulk shrinking rate
of B**8 is around 5%, while the rate of the latest
ammoniasynthesis
producing in
domestic is around *0%. The shrinkage rate influences the activity
and longevity of the furnace layers directly. If the shrinkage is
high, there will be bridging phenomena between the catalyst
particles causing the gas flow distributed unevenly. The rate is
especially important to shift reactor on axial
direction.
2. The
active component distributing evenly
Cu
isdistributed evenly and
inmultiple
formsand
has big specific surface. So it has the permances of easier
reductive, good active. the initial reduction temperature of B**8
series of catalyst is generally at **0 ℃, reduction time is in *0
hours (reduction space velocity is faster than **0 per hour). The
inlet temperature at the first period using is around **0
℃.
3.
Good strength and strong resistance to erosion
performances
We
inspect the catalysts by using the flow for as 6 to 7 times as the
axial velocity on them, consequently, there is no broken. After
boiling half an hour in the boiling water, the catalyst particles
are all intact.

Packing and
Transportation：
1. Lined with plastic
film bag with plastic packing seal, *0 kg net weight a barrel, and
barrels are marked tags within the catalyst model, batch number,
net weight, production team, production date,
etc.
2.In the transportation process
should either be paid attention to in the keep away from moisture,
or avoid rolling, falling touch or intensely shocking, and should
prevent the rain facilities; Products should be stored in a dry and
ventilated place, against pollution or moisture.
