Abstract: The present disclosure relates to a single shell open interstage reactor (“SSOI”). The SSOI comprises a first reaction stage, an interstage heat exchanger, an open interstage region, and a second reaction stage. The SSOI may be configured for upflow or downflow operation. Further, the open interstage region of the SSOI may comprise a supplemental oxidant feed. When the open interstage region comprises a supplemental oxidant feed, the SSOI may further comprise a supplemental oxidant mixing assembly. Processes for producing acrylic acid through the oxidation of propylene are also disclosed.

Abstract: An object is extruded to have the form of a cage, the cage defined by spokes corresponding to several extrudate streams. The spokes bound a hollow interior and extend between opposed hub regions where the spokes are fused together. In manufacturing the objects, ceramic material is extruded through multiple dies arrayed around an extrusion axis, the dies mounted to permit controlled movement of the dies during the course of extrusion to vary the position of extrudate streams exiting the dies.

Abstract: Described herein are flexible seals for directing fluid flow in a tubular reactor, such as a reformer, for enhancing heat transfer and reactor efficiency. The seals can be made of corrugated metal foil that is expandable in the radial direction for accommodating the expansion and contraction of reactor components in the tubular reactor during operation. The seals can block or redirect fluid flow through the reactor. Fluid is directed to the interior of the reactor by the seals and bypass around the outer circumference of the reactor components is reduced or eliminated.

Abstract: A wire standoff suitable for use in a tubular reactor, such as a reformer, is described. The wire standoff includes a portion or segment positioned between an outer reactor tube and one or more reactor components located within the tube. The reactor components and the outer tube are prevented from coming into directed contact with one another by the positioning of the wire standoff. The wire standoff can be secured to a reactor component at one of its ends or to a washer located between stacked reactor components. Prevention of the reactor components from contact with the outer tube promotes fluid flow through the reactor and can enhance heat transfer and reactor efficiency for carrying out catalytic reactions.
