SAL-116 ZnO Desulfurization Catalyst

Description

Model:SAL-116

ZnO Desulfurization Catalyst SAL-116 is used for removing sulfide of coal, natural gas, coke oven gas, oil field gas, refinery gas, syngas, gas and other gases and liquid hydrocarbons, propylene, naphtha and other liquid materials. It can prevent sulfur poisoning of following section catalysts and improve product quality.

The main reactions are as follows:

ZnO + H₂S → ZnS + H₂O +76.62 KJ/mol

ZnO + COS → ZnS + CO₂ +126.04 KJ/mol

ZnO + C₂H₅SH → ZnS + C₂H₄ + H₂O + 137.83 KJ/mol

2ZnO + CS₂ →2ZnS + CO₂ + 283.45 KJ/mol

Industrial Applications

The catalyst is suitable for sulfide in catalystic dry gas, coking dry gas, oil field gas, refinery gas and naphtha purification plant;

The catalyst is suitable for sulfide purification device in coal synthesis gas.

Physical and Chemical Properties

Operation Conditions

Space velocity of the feed gas: 500 ~ 3000h-1(g), 0.5 ~ 3h-1(l)

Operation temperature: 200 ~ 400℃
