The work about choice of hydroisomerization catalyst systems and scale up in catalyst preparation was presented. Performance and regeneration behaviors tested in different laboratory reactors and a 1000 t/a pilot plant were discussed, which offers the information for commercial use of this process. Mechanism for coke formation was also proposed.展开更多
