A system for producing catalytically treated pyrolytic vapor.The system comprises a pyrolysis reactor (100) configured to produce pyrolytic vapor and a catalytic reactor (200) limiting abed area (B) into which a fluidized catalyst bed is configured to form in use. The catalytic reactor (200) comprises a static mixer (300) configured to spread the particulate catalyst within the bed area (B). Thus, the catalytic reactor (200) is configured to produce a mixture of the particulate catalyst and the catalytically treated pyrolytic vapor from the pyrolytic vapor. A method for producing catalytically treated pyrolytic vapor. The method comprises producing pyrolytic vapor and allowing at least a clean part of the pyrolytic vapor to chemically react in the presence of the particulate catalyst to produce a mixture of the particulate catalyst and catalytically treated pyrolytic vapor. The method comprises mixing, in the bed area, the pyrolytic vapor and the particulate catalyst with a static mixer.

Tightly-coiled helical ducts for centrifugal air separators may be formed with the tools and methods disclosed herein. A helical coil toolset includes a helically grooved mandrel and an entry block. The helical groove of the mandrel has a small helix inside diameter relative to a width of the helical groove. The entry block has a guide channel to guide a tube to the helical groove and a mandrel channel to receive the mandrel. Methods include forming tubing into a tightly-coiled helical duct by filling a tube with fine particles, positioning the tube in the helical groove of a helically grooved mandrel, fixing the tube relative to the mandrel, assembling an entry block around the tube and around the mandrel, and bending the filled tube around the helically grooved mandrel into the tightly-coiled helical duct by rotating the mandrel relative to the entry block.

The specification and drawings present a new apparatus and method for continuously providing an oxygen-enriched gas/air using a relative motion of selected surface(s) of an apparatus (such as fossil-fueled combustion device/vehicle) relative to an atmospheric air with a speed exceeding a threshold value for, e.g., improving combustion, exhaust and related properties of the apparatus. An oxygen-enriched gas/air layer can be formed along/near each aforementioned surface from the atmospheric air due to pushing the atmospheric air along the surface(s) during that relative motion and collected by corresponding collector gate(s) located inside the apparatus near/adjacent to the corresponding surface. The apparatus can be an object (e.g., a vehicle) moving through the atmospheric air with a relative speed exceeding the threshold value. Alternatively, the apparatus can be a stationary object (e.g., a power generator) while the atmospheric air, having a desired speed exceeding the threshold value, is moved/blown toward the stationary object.
