Catalytic dewaxing of middle distillates

Patent ·
OSTI ID:6471556
The fractionation and stripping equipment of a middle distillate catalytic dewaxing unit may be eliminated by integrating the catalytic dewaxing unit with a catalytic cracking unit. The light cycle oil sidestream from the cat cracker fractionator, bypasses the sidestream stripper and serves as the feed to the catalytic dewaxing unit. The dewaxed product is separated into a gasoline fraction which is recycled for fractionation in the cat cracker fractionator and a fuel oil fraction which is recycled to the cat cracker sidestream stripper for removal of light materials to produce a low pour fuel oil meeting product specifications.
