Priamary Reforming Catalyst

1. 概述 General Introduction

SCST-201、SCST-202、SCST-203系列烃类一段转化催化剂用于天然气、焦炉气等制氢、制合成氨、甲醇装置，甲烷、高碳烃和水蒸汽在催化剂催化下反应生成H₂ 、CO 和CO₂.

The primary steam-reforming catalysts SCST-201, SCST-202, SCST-203 are used for the reaction of methane, high-carbon hydrocarbon and water vapor to produce hydrogen, carbon monoxide, carbon dioxide under the catalyst on the hydrogen plants by natural gas, coke oven gas, ammonia plant and the methanol plant.

主要反应如下：the main reactions are as following:

 CH₄ + H₂O=CO + 3H₂   -206.3 kJ/mol

CH₄+ 2H₂O=CO₂ + 4H₂  -165.3 kJ/mol

4. 催化剂特性Product Advantages

1) 低温活性好，在400℃就有明显的活性和较高转化率；

Good activity at low temperature: apparent activity and high conversion rate at 400 ℃;

2) 抗析碳能力强，适用于低水碳比长时间运行；

Strong anti-carbon ability: long time running at low water-carbon ratio;

3) 强度高、运行阻力低，特别是还原后的强度达到国际领先水平；

High strength, low running resistance: reaching the international advanced level after reduction;

4) 抗毒性能好、活性和热稳定性更强，硫、氯等轻度中毒时，通过优化操作参数即可自行再生，催化剂严重中毒后可以进行器内再生；

Good Anti-toxic performance and thermal stability. When sulfur and chlorine are mildly poisoned, the catalyst can regenerate by itself by optimizing the operating parameters;

5) 外形设计结构合理、性能稳定；催化剂六孔圆柱体，具有外表面大、空隙率高、阻力降低、气流发布均匀等特性；

Reasonable structure design: the six-hole cylinder of catalyst has the characteristics of large outer surface, high porosity, low resistance and uniform air distribution;

6) 具有优良的还原性，可以直接天然气进料、自循环还原活化，节能显著。

Excellent reducibility and save energy remarkably. It can feed natural gas directly, reduce and activate by self-circulation.
