Abstract:
Methods and systems for the production of linear alkylbenzens are described herein. The methods and systems incorporate the novel use of a high shear device to promote dispersion and mixing of one or more olefins (e.g. propylene) with an aromatic. The high shear device may allow for lower reaction temperatures and pressures and may also reduce reaction time with existing catalysts.

A system for the production of cumene hydroperoxide from oxidation of cumene, the system comprising a reactor and an high shear mixer the outlet of which is fluidly connected to the inlet of the reactor; the high shear mixer capable of providing a dispersion air gas bubbles within a liquid, the bubbles having an average bubble diameter of less than about 100 microns.
Abstract:
Herein disclosed is a method for thermal cracking or steam cracking of hydrocarbons comprising: supersaturating a hydrocarbonaceous liquid or slurry stream in a high shear device with a gas stream comprising steam or hydrogen and optionally one or more C1-C6 hydrocarbons to form a supersaturated dispersion; and introducing the supersaturated dispersion into a thermal cracking or steam cracking reactor to generate a product stream. In some embodiments, the method further comprises contacting the supersaturated dispersion with a cracking catalyst in a slurry, a fluidized catalyst bed, or a fixed catalyst bed. In some embodiments, the cracking catalyst is mixed with the hydrocarbonaceous liquid or slurry stream and the gas stream in the high shear device. Herein also disclosed is a system for thermal cracking or steam cracking of hydrocarbons.
