采用水热合成法合成长条状大晶粒镁碱沸石分子筛，采用XRD、SEM及NH3-TPD程序升温脱附进行表征，结果表明，实验室小试合成、中试放大及工业生产得到的3种分子筛物化指标基本一致，该分子筛催化剂在正丁烯骨架异构反应中均表现出高活性、高选择性和再生性能好等优点。工业应用结果表明，SC518催化剂在重时空速6 h-1和异丁烯收率不低于30%条件下，工业装置运行中单程运行周期不小于43天，副产物收率小于1%。%The ferrierite zeolite catalyst was synthesized by hydrothermal method. Three samples obtained from laboratory,pilot plant and industrial scale were characterized by means of XRD,SEM and NH3-TPD. The results indicated that the three samples had basically the same physicochemical properties and exhibited the advantages of high activity and selectivity and the excellent regeneration performance in the skeletal isomerization of n-butene. The commercial application results showed that under the condition of WHSV 6 h-1 and i-butene yield not less than 30%,SC518 catalyst of industrial scale ran over 43 days, and the yield of by-product was less than 1%.
