Hydrotreating/isomerization process to produce low pour point distillate fuels and lubricating oil stocks |
摘要 |
A process for dewaxing a hydrocarbon feedstock with a relatively high pour point and containing paraffins selected from the group of normal paraffins and slightly branched paraffins and sulfur and nitrogen compounds which comprises subjecting said oil to hydrotreating in a hydrotreating zone operated at hydrotreating conditions sufficient to remove at least a portion of said sulfur and nitrogen compounds and subjecting said hydrotreated oil to catalytic dewaxing by contacting said oil with a catalyst comprising zeolite beta having a silica/alumina ratio of at least 30:1 and a hydrogenation/dehydrogenation component under isomerization conditions.
