In order to process Fischer-Tropsch(F-T)synthetic oil,on the basis of optimizing the acidic component of the catalyst to improve the temperature sensitivity of the catalyst and selecting the suitable mesoporous silica-aluminum components,catalyst RCF-1 for isomerization-hydrocracking of F-T wax was developed,which had low temperature sensitivity and high selectivity of middle-distillate.Based on this catalyst,the low-temperature F-T hydrotreating and hydrofinishing CFHL technology was employed.The commercial application of the catalyst RCF-1 showed that the cetane number and freezing point of the diesel distillate produced by the isomerization-hydrocracking unit were 76 and-33 ℃,respectively,using the low-temperature process for the hydrogenation of F-T synthetic CFHL.The stabilization-hydrogenation and isomerization-hydrocracking naphtha fractions are particularly suitable as steam cracking feed.
