Abstract: The present invention relates to devices for maintaining a state of equilibrium, and process set-ups to perform equilibrium reactions using heterogeneous catalysts, in particular said reactions are equilibrium reactions where at least one reaction product is volatile. The invention is especially interesting for enzymatic reactions using immobilized enzymes, although it is also useful for pure chemical reactions. The invention is characterized by a combination of non-impact mixing of components and volatilization and/or removal of excess molecules, thereby maintaining a state of equilibrium or driving an equilibrium reaction. The present invention also relates to devices and/or process set-ups and materials made using said processes.

Abstract: The present invention discloses an immersion type rotating packed-bed reactor and an application thereof. A rotor filler is immersed in materials in the reactor; under the driving of the rotation of a rotor, the materials in the reactor form a loop; and when passing through the filler, the materials are fully sheared and dispersed into fluid micro-elements, so that the mass transfer rate and the reaction rate are increased. A feeding assembly simultaneously introduces materials of different phases to an inner edge of the rotor, a retaining ring and a baffle function to break a vortex, and a heat exchange assembly can maintain a system in a suitable temperature range. The present invention is suitable for heterogeneous systems such as a gas-liquid system and a liquid-liquid system. Compared with a conventional rotating packed bed, the material contact time is long, so that the reaction is more complete.

Abstract: A spin contactor is provided for contacting a particulate with a fluid. The spin contactor has a containment section that may contain the particulate, a fluid inlet, and a fluid outlet. The containment section comprises an upper particulate separator, a lower particulate separator, and a conical wall. In most cases, the spin contactor includes a shaft to be operatively coupled to a means for spinning the spin contactor. The fluid is drawn upwardly through the fluid inlet to contact the particulate and then expelled through the fluid outlet. A process of treating a fluid composition is provided by sending the fluid composition through the spin contactor comprising particulates.
