Methanol synthesis
catalyst
1. Productfeatures
and scope of application
BSMS***9
Methanol synthesis catalyst is widely applicable to methanol plants
employing various technologies, including medium- or low-pressure
processes such as Lurgi and ICI. Properties of the catalyst were
greatly enhanced after a remarkable improvement was made on its
preparation technology. As the result, the catalyst is featured by
higher activity, higher space-time yield and CO conversion, better
thermal stability and tolerance to heat, longer service life,
better selectivity, higher methanol concentration and less organic
by-products in raw product, wide range of operation condition, ease
in reduction and operation, higher strength and little pressure
drop across the bed.

Packageand
storage
The catalyst is packed in iron barrels lined inside
with plastic bags. It should be stored in dry and well-ventilated
place. The catalyst can usually be stored for several years without
remarkable deterioration in its properties.
