An object of the present invention is to provide a photocatalytic sheet configured to perform disinfection independent of the state of external light.

A photocatalytic sheet 50 according to the present invention includes a sheet 10 having a photocatalytic layer 17 on one surface, and an optical fiber 20 embedded in the sheet 10 and configured to supply ultraviolet light UV from inside of the sheet 10 to the photocatalytic layer 17. In the photocatalytic sheet, ultraviolet light is supplied from the optical fiber disposed in the sheet to the photocatalytic layer coated on the surface of the sheet (ultraviolet light is supplied from the back of the photocatalytic layer). This configuration allows for disinfection independent of the state of external light.

The present disclosure sets forth a proposed solution to decarbonize the acrylic chemicals industry with a lactic-to-acrylic technology producing bio-based acrylics that are sustainable and eco-friendly and are at cost parity with petrochemicals. In the present disclosure, catalysts comprising potassium and zeolites were relied on as the catalyst base. It has been found high yield lactic-to-acrylic technology of the present disclosure is industrially feasible at new or as an add-on to existing bio-refining facilities throughout the Midwest due to the high yields achieved.

An active catalyst for ammonia synthesis is integrated with a specialty sorbent in a composition or composite, such that the catalyst portion and the sorbent portion are in direct intimate contact, which overcomes the thermodynamic limits for conversion. The sorbent may comprise a metal halide absorbent, zeolite adsorbent, other material absorbents or adsorbents, to capture ammonia as it is produced in intimate or near molecular contact with the catalyst, wherein the composition/composite may be provided in the form of a granular or pellet structure. By removing ammonia essentially as it forms, the forward reaction for producing ammonia can continue nearly unabated such that high net conversion can be achieved in a single pass or cumulative within segmented reactors as operated in series.

A denitration catalyst structure includes: a rectangular frame body having a gas inlet and a gas outlet; a plurality of plate-like catalytic elements each of which has a gas inlet-side edge, a gas outlet-side edge, and two side edges and contains a catalytic component; and a plate-like draft stopper having a gas inlet-side edge, a gas outlet-side edge, and two side edges. The plurality of plate-like catalytic elements are stacked and housed in the frame body with the side edges aligned, with a space between the stacked plate-like catalytic elements and between an inner surface of the frame body and the side edges of each plate-like catalytic element to allow a gas to pass from the gas inlet to the gas outlet through the space. The plate-like draft stopper is arranged between the inner surface of the frame body and the side edges of each plate-like catalytic element.
