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: Polyolefin polymerization performed by contacting in a reactor an olefin monomer and optionally a comonomer with a catalyst system in the presence of induced condensing agents (ICA) and optionally hydrogen. The ICA may include two or more ICA components where the composition of the ICA (i.e., the concentration of each ICA component) may affect the polyolefin production rate. Changes to the relative concentration of the two or more ICA components may be according to ICA equivalency factors that allow for increasing the polyolefin production rate while maintain a sticking temperature, increasing polyolefin production rate while increasing the dew point approach temperature of the ICA, or a combination thereof.

Abstract: In the operation of an oxidative dehydrogenation (ODH) process, it is desirable to remove oxygen in the product stream for a number of reasons, including to reduce oxidation of the product. This may be achieved by having several pre-reactors upstream of the main reactor having a catalyst system containing labile oxygen. The feed passes through one or more reactors saturated with labile oxygen. When the labile oxygen is consumed through a valve system, the pre-reactor accepts product from the main reactor and complexes reactive oxygen in the product stream until the catalyst system is saturated with labile oxygen. Then the reactor becomes a pre-reactor and another pre-reactor becomes a scavenger.
