organic sulfur hydrolysis catalyst LYT-511

A, product features and uses:

In the process of synthetic ammonia with coal as raw material, the trace organic sulfur removal by normal temperature hydrolysis process, which has the advantages of simple operation, low cost of the catalyst. Disadvantage is the low activity is poor, and often due to capillary condensation of saturated water vaporand water and inactivation, it is demanded for heating and cooling equipment in thebefore and after hydrolysis agent. At the same time to avoid high concentrations of H2S and trace oxygen reaction caused by hydrolysis catalyst sulfation inactivation,hydrolytic agent before setting activated carbon or iron oxide from high concentration H2S. This long process, large equipment investment, for theconversion and removal of trace organic sulfur is neither reasonable nor economic.In view of the above problems, we developed a sulfur tolerant catalyst for organic sulphur hydrolysis. The activity of titanium dioxide as active component, add special additives, with active temperature range, high conversion rate of organic sulfur,sulfur resistant, resistant to high steam / gas ratio, loading the catalyst, in theorganic sulfur removal was transformed into inorganic sulfur, which greatly simplifies the process flow, improve the desulfurization efficiency. Can replace theCo Mo HDS process using the catalyst, and low cost, can realize the conversion of organic sulfur transformation without equipment, to ensure the normal operation ofsubsequent section production.

Reaction principle:

COSH2O = H2SCO235.53KJ / mol

Air speed: 2000 ~ 3000h-1

Four, packaging and storage

Woven bag with 1, LYT - 511, lined with plastic bag, prevent moisture absorptionand chemical pollution.

Avoid scrolling should be 2, in the process of transportation, collision and vibration,so as to avoid crushing.

3, good packaging products should be stored in dry warehouse, can not be in contact with other chemicals, to prevent pollution, damp and broken.
