摘要: An apparatus for conducting aqueous liquid media includes a plurality of static mixers, a gas distributor assembly with a plurality of nozzles, at least one impeller having blades attached thereto and a plurality of static mixer assemblies having flow guide elbows and collectors. The static mixer assemblies are independently and separately mounted to orient to the current leaving the blade tips of the impeller. Swirlers are also described as being utilized in place of the static mixers.

摘要: A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.
