Crude Benzene Hydrogenation Catalyst SCST-531
- Application
SCST-531 crude benzene hydrogenation catalyst is mainly used for the removal of organic sulfur such as mercaptans, sulfides, disulfides, and thiophene in coking crude benzene. The reaction equations are as follows:
CS2+4H2=CH4+H2S
C4H4S+4H2=C4H1o+H2S
COS+H2=CO+H2S
CH3SCH3+2H2=2CH4+H2S
C2H5SH+H2=C2H6+H2S

- Application Fields
Hydrogenation section of coking crude benzene in the oil refining industry.
- Catalyst Characteristics
High desulfurization activity;
Small loss of three benzenes;
Long service life and good stability.
- Packaging, Storage and Transportation
The finished catalyst is packed in plastic drums or iron drums lined with plastic bags;
Rolling or impact is strictly prohibited during transportation;
The catalyst should be placed in a dry and ventilated place, strictly preventing moisture and chemical contamination;
When stored outdoors, place sleepers at the bottom and cover with canvas for rain protection;
During shipping, strictly prevent seawater (river water) from entering to avoid affecting the performance of the catalyst.
