This disclosure provides improved processes for converting aromatic hydrocarbons, such as benzene/toluene, alkylation, transalkylation, or isomerization. In an embodiment, a process comprises utilizing a passivated reactor to reduce deactivation of a molecular sieve catalyst. Additional measures such as the use of an auxiliary catalyst and/or an elevated reactor pressure may be used to further reduce deactivation of the molecular sieve catalyst.

The present disclosure relates to a dispersed metal nanoparticle synthesis method and metal nanoparticles prepared thereby. Specifically, the present disclosure relates to a method of effectively preparing a dispersed metal nanoparticle using Taylor vortex flow even when using a small amount of stabilizer or using no stabilizer, and well-dispersed nanoparticles obtained thereby.

An equilibrium approach reactor with the ability to receive a highly variable gas and normalise it to a useful quality, and further to utilise the energy from the gas itself to robustly elevate the operating temperature, to ensure good mixing and high conversion while having the ability to handle solids in multiple states.

Embodiments of the present technology are directed to air treatment reactor modules, and associated systems and devices. An exemplary reactor module can include a housing, an ultraviolet (UV) light source disposed within the housing, and a plurality of hollow elongate conduits disposed within the housing and peripheral to the UV light source. The UV light source and individual conduits can extend in a lateral direction perpendicular to the direction of air flow through the reactor module. The conduits can include a plurality of holes and be at least partially coated with a photocatalytic material. The housing can have an inner surface comprising a reflective material that, in operation, reflects UV light emitted from the UV light source.

A metal chloride generator is provided. The metal chloride generator is a metal chloride centrifugal reactor that can be operated under conditions sufficient to cause metal particles and chlorine in the generator to be brought into contact with one another and react using centrifugal force to form metal chloride. A process for manufacturing titanium dioxide that utilizes the metal chloride generator is also provided.
