Dewaxing with nickel-silicalite catalyst

摘要

A process for dewaxing middle distillate petroleum products includes the steps of introducing a middle distillate petroleum fraction having a boiling point in the range of from about 160<o>C to about 500<o>C into a reaction zone and contacting the middle distillate petroleum fraction in the reaction zone at temperatures of from about 500<o>F to about 700<o>F and pressures of from about 300 psig to about 2000 psig with a nickel-containing silicalite catalyst.
