耐硫变换催化剂QCS装填及升温硫化总结

QCS Sulfur Resistant Shift Catalyst Loading and Heating Vulcanization

介绍了耐硫变换催化剂QCS型装填前的准备工作,由于催化剂的特殊性,在装填过程用一种较理想的方法保证其不能破碎且装填的均匀,升温硫化充压过程中严格控制冲压速率,各个阶段严格控制空速、温度、变换炉压差、H2含量控制在10%左右,变换炉出口H2S与进口一致,表示硫化结束,3小时硫化强化期结束后,缓慢将入工段大阀全开,系统全部接气,系统转入正常生产。

Introduced QCS type sulfur resistant shift catalyst is introduced the preparing work befure loading, due to the particularity of catalyst, in loading process in a more ideal method to ensure its not broken and uniform loading, heating vulcanization pressurized strict control in the process of stamping speed, strictly control the airspeed at various stages, temperature, pressure differential transform furnace, H2 content is controlled at about 10 %, conversion furnace outlet H2S agree with imports, said end of sulfide, vulcanization improved period after the end of 3 hours, will slowly into the section valve fully open, system of all the songs, the system to normal production.
