Claim Text:
1. A method of preparing a catalyst for paraffin isomerization, comprising: a) mixing one or more rare earth compounds with a TON molecular sieve to form a first mixture, drying and calcining the first mixture to obtain a TON molecular sieve modified by one or more rare earth oxides; b) mixing one or more zirconium compounds with an inorganic refractory oxide to form a second mixture, drying and calcining the second mixture to obtain an inorganic oxide modified by zirconium oxide; c) kneading the TON molecular sieves comprising one or more rare earth oxides and the inorganic refractory oxide modified by zirconium oxide to form a third mixture, drying and calcining the third mixture to obtain a catalyst carrier; and d) loading a compound of a noble metal of group VIII on the catalyst carrier to obtain a catalyst precursor, drying and calcining the catalyst precursor to obtain the catalyst for paraffin isomerization.
