Isomerization of high sulfur content naphthas

摘要

This invention relates to a process for isomerization of sulfur containing isomerizable hydrocarbons, especially saturated hydrocarbons having from 4 to 7 carbon atoms per molecule. More specifically, this invention relates to a process for isomerizing a sulfur containing combined feed where the sulfur compounds are controlled to achieve a level of from about 5 wt. ppm to about 150 wt. ppm utilizing a catalyst composition containing a hydrogen form crystalline aluminosilicate, a Group VIII metal, a refractory oxide and having a surface area of at least 580 m2/g.
