Industrial Application of QDB-06 Sulfur-Tolerant Shift Catalyst in Isothermal Shift Unit
Since the transformation of the synthetic ammonia shift unit from a four-stage adiabatic sulfur-tolerant shift to isothermal shift,the catalyst used is changed to QDB-06 sulfur-tolerant shift catalyst.The process flow,catalyst loading and heating vulcanization of the isothermal shift unit are introduced.The actual operation for over 6 months shows that the QDB-06 sulfur-tolerant shift catalyst has good low temperature activity,particle strength,and strength stability,which can fully meet the shift requirement and isothermal shift conditions.
