SCST-201 Primary Steam-Reforming Catalyst

Model：SCST-201

The primary steam-reforming catalysts SCST-201, SCST-202, SCST-203 are used for the first conversion plant with natural gas or methane-rich gas to produce ammonia, methanol, hydrogen. The principle is that natural gas reacts with steam to produce hydrogen, carbon monoxide, carbon dioxide. They are new type of energy-saving primary reforming catalysts.

The main reactions are as follows:

CH₄ + H₂O_（g）→ CO + 3H₂ －206.3 KJ/mol

  CH₄ + 2H₂O_（g）→ CO₂ + 4H₂ －165.3 KJ/mol

CO + H₂O_（g）→ CO₂ + H₂ + 41.19 KJ/mol

【Industrial Applications】

• The catalyst is suitable for the system of ammonia, methanol, hydrogen plant using natural gas and coke oven gas;
• The catalyst is suitable for the hydrogen plant using catalytic dry gas, coking dry gas;
• The catalyst is suitable for methanol synthesis and ammonia plant using oil field gas, refinery gas, naphtha.

【Physical and Chemical Properties】

          The shape, size and activity content can be customized subject to Customer's requirement.

【Operation Conditions】

• Inlet temperature of the reformer tube: 350 ~ 650℃
• Outlet temperature of the reformer tube: 600 ~ 950℃
