Description
Main Catalyst Product
Type
1: Broad Temperature Type
of Sulfuric Acid Catalyst: S**1.
Type S**1:There are four products of type S**1, in
details, they are S**1 (Cylinder); S***-H (Ring); S***-MH (Star
ring); S***-YH (Three-Ribs Cylinder).
Type S**1 Catalyst is a medium broad temperature vanadium
catalyst which promotes the oxidation from SO2 to SO3, and it is
developed by China. With *0 years of manufacturing S**1 catalyst,
it has reached the international advanced level. Due to its
high-quality and steady performance,
The advantages of S**1 are as listed.
Wide applicability, broad range of temperature, high conversion,
and high mechanical strength etc. Ring or plum blossom shaped
catalysts have solved some problems that cylinder shaped catalyst
encountered; namely, they are small pellets, high pressure drop and
high energy consumption, bad resistance of dust accumulation.

2: Low Temperature Type
Sulfuric Acid Catalyst: S**8.
Type S**8: S**8 Cylinder; S***-H (Ring); S***-MH (Star ring);
S***-YH (Three-Rib Cylinder)
Type S**8 Series sulfuric acid catalysts are invented in early *0s
by China. The advantages of them are outstanding. In general, they
are low ignition temperature, high activity in low temperature,
high-resistant crushed strength etc. If can be used together with
medium temperature type catalyst, such as, S**1, you can make more
profits; for instance, high conversion, and lowering environmental
pollution.

Vanadium Catalyst
Applications (Only for Reference)
- Rangeof Application
Vanadium pentoxide series of sulfuric acid catalysts could be used
in the process of sulfuric acid production, to be more specific, is
the process of SO2+I/2O***-SO3. With the help of Vanadium Catalyst,
the rate of conversion can be improved greatly. It could guarantee
the air speed of operation to add ****0% more when using type star
ring catalysts or ring catalysts.
Vanadium catalyst can be applied in many fields, such as,
sulfur-based acid production, pyrite-based acid production,
nonferrous smelting gas-based acid production, gypsum-based acid
production etc.
- Loading and
Distribution of Catalyst
For the fourth and fifth stage conversion, the common use amount of
catalyst is ******0L (t/d **0%H2SO4), while in the process of
smelting gas-based acid production, the amount can be 1.**1.8m3
(km3 gas/h), but under the condition of using plum blossom shaped
or ring-shaped catalyst, the amount can increase ****0%, to make
sure operating gas velocity steadier.

3. Operating
Requirements
1). Type S**1 series are broad temperature catalysts which suit for
every bed of converter.
2). Type S**8 is low temperature catalysts which suit for 1/3 top
of the first bed to decrease inlet operating temperature, and 4th
bed, 5th bed to improve equilibrium conversion and decrease gas
emission.
