Product Information

LHTCS-305 Zinc Oxide Desulfurization Catalyst 

1. Product Introduction

LHTCS-305 Zinc Oxide Desulfurization catalyst is applicable to desulfurization of residue cracking gases or syngas and purification of feed gases for organic synthesis processes. It is suitable for both higher (350--408°C) and lower (150--210°C) temperature use. It can convert some simpler organic sulfur while absorbing inorganic sulfur in gas stream.

 

Main reaction of the desulfurization process is as follows:

(1) Reaction of zinc oxide with hydrogen sulfide

   H2S+ZnO=ZnS+H2O

 

(2) Reaction of zinc oxide with some simpler sulfur compounds in two possible ways:

a. Organic sulfur compounds, catalyzed by zinc oxide, react with hydrogen to form  hydrogen sulfide:

  CS2 + 4H2 = CH4 + 2H2S

  C2H5SH + H2 = C2H6 + H2S

  Then hydrogen sulfide is absorbed by zinc oxide

  H2S+ZnO=ZnS+H2O

b. Zinc oxide reacts directly with organic sulfur compounds

  COS + ZnO = ZnS + CO2

LHTCS-305 is an ideal desulfurization adsorbent for deep purification cases, especially those at higher temperature (350--400°C).
