1. 概述 General Introduction

SCST-111预转化催化剂适用于以轻油、石脑油、液化气、轻烃、含烃干气、等烃类原料和水蒸气预转化制取富甲烷气过程。此预转化催化剂气可进一步用于制取氢气、氨合成气、甲醇合成气或城市煤气。

Pre-reforming catalyst SCST-111 is mainly to produce methane-rich gas by pre-conversion of naphtha, light oil, liquefied petroleum gas, light hydrocarbon and other hydrocarbon feedstock with steam. It also could produce hydrogen, ammonia synthesis, methanol synthesis and natural gas for household use.

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

2CnHm+3nH₂O=nCO+nCO₂+(3n+m)H₂

CO+3H₂=CH₄+H₂O+206 kJ/mol

CO₂+4H₂=CH₄+H₂O+165 kJ/mol

CO+H₂O=CO₂+H₂+41 kJ/mol

3. 操作工艺条件Operation Conditions

4. 催化剂特性Product Advantages

1) 高镍稳定分散在多孔载体上，具有良好的低温活性、活性稳定性；

Nickel dispersion in the porous carrier, with good activity at low temperature, activity stability;

2) 可以提供氧化态或还原态催化剂；氧化态催化剂需要在器内还原活化，还原态催化剂直接进料使用；

Can provide oxidation or reduction state of the catalyst;

3) 烃类原料单一或混合进料，原料切换、原料比例调整不影响催化剂正常性能；

Single or mixed material switching, material ratio adjustment does not affect the normal performance of the catalyst;

4) 具有优良的抗工况波动能力，操作弹性大，可以冷态并入系统。

Excellent resistance to working conditions fluctuations and the gas could enter the system at room temperature.
