ASTM Standard Zinc Oxide Desulfurization Agent

Description
High Light:

zinc oxide adsorbent

,

desulfurization catalyst

Zinc oxide desulfurizer, Biogas desulfurizer, H2S removal, LSDS2 series

 

Usage and Features

The feed gas can be natural gas, petroleum gas, light oil gas, synthetic gas, coal gas, semi-water gas and other various gases. Usage of type DS2 zinc oxide desulfurizer at a low temperature can guarantee high purity of gases containing large amount of inorganic sulfur(1-2 g/m3) and small simple organic sulfur(such as COS,CS2). It's suitable to remove hydrogen sulfide both at high(350-450C and low temperatures(30-350C), while it's better for high temperature.

 

Zinc oxide desulfurizer can also be used as a protective agent for synthesizing carbinol, hypoallergenic and methanation catalyst.

 

The usage:

Serve as raw material of fine desulfurization when using natural gas or light oil vapor gas conversion makes hydrogen or ammonia

Serve as conversion catalyst to protect methane before conversion catalyst when coke-oven gas makes ammonia

Serve as low transformation protectant before copper low temperature conversion catalyst when using natural gas or naphtha as raw material makes ammonia or hydrogen

Other techniques for fine desulfurization

Features of chemical equation

ZnO+H2S=ZnS+H2O

CS2+4H2=2H2S+CH4

COS+H2=H2S+CO

COS+ZnO=ZnS+CO2
