Abstract
An improved process for catalytically dewaxing low nitrogen content hydrocarbon oils, such as distilled hydrocracker bottoms which normally form by-product naphtha of variable, but poor octane quality. The improvement is achieved by doping the low nitrogen content oil with a small amount of high nitrogen content gas oil, resulting in a by-product naphtha having a clear research octane of about 90, which octane is relatively insensitive to adjustment of pour point during processing.
