1. 概述 General Introduction

SCST-302型氧化锌精脱硫剂用于脱除煤、天然气、焦炉气、油田气、炼厂气、合成气、变换气等多种气体及液态烃、丙烯、石脑油、等液态原料的硫化物，以保护蒸汽转化、低变、甲烷化、甲醇、合成氨、聚丙烯和羰基合成等含镍、铜、铁及贵重金属催化剂和提高产品质量。

ZnO Desulfurization Catalyst SCST-302 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, naphthaand other liquid materials, to protect the nickel catalyst, copper catalyst, iron catalyst and pecious metal catalyst such as the catalyst of steam reforming, low temperature shift, methanol synthesis, ammonia synthesis and so on, and improve product quality.

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

ZnO+H₂S==ZnS+H₂O           +76.62KJ/mol

ZnO+COS==ZnS+CO₂             +126.04KJ/mol

3. 操作工艺条件Operation Conditions

4. 催化剂特性Product Advantages

1) 耐水性好，在水蒸气参与反应的工序，催化剂具有强度高、不易粉化，运行阻力低等特点；

A high resistance towards water , the catalyst has a high strength, low running resistance when the water vapor involved in the reaction process ;

2) 耐高压、高空速，在高压高空速运行下催化剂运行寿命高于国内同行催化剂；

Life is higher than other peer catalyst at high pressure and high space velocity operation condition;

3) 新型生产工艺，催化剂硫容大，在一定温度下硫容超过30%；

Excellent sulfur capacity: at a certain temperature, sulfur capacity could more than 30%;

4) 比表面积大、转化率高，催化剂出口H₂S一般小于0.01ppm。

Higher surface area and higher conversion, outlet H₂S less than 0.01ppm.
