Abstract: A catalytic static mixing reactor has a conduit casing defined about an axis of a fluid flow. A catalyst is deposited on a mixing element. The mixing element is adapted to be inserted in the conduit. The element provides an exceptionally high surface area and is formed to obstacle the primary flow inducing a first order mixing phenomenon. The element is formed with at least one irregular surface or edge capable of inducing a second order mixing phenomenon. The irregular surface is adapted as a catalytic supporting surface. The supporting surface supports the deposition of the catalyst thereon so that a third order chemical reaction phenomenon is coupled with that of said first and second order mixing phenomenon at the catalytic surface so that a reactant to be converted in the fluid flow is converted to at least one predetermined product during said first and second order mixing phenomenon.

Abstract: A fast pyrolysis system includes an auger housing having an inlet, an outlet, and an inner wall. A rotatable auger is mounted in the housing. The auger has surfaces defining at least one spiral channel. The spiral channel is tapered from a first depth adjacent the housing inlet to a second lesser depth adjacent the housing outlet. The auger is rotatable to propel particulate materials from the housing inlet toward the housing outlet to heat the particulate material to a first temperature sufficient to convert at least a portion of the particulate material into a vapor. A heat exchanger transfers a heat of vaporization from a heated medium to the auger housing inner wall. A filter assembly is connected downstream to the housing outlet in order to filter char fines from the vapor. A condenser is connected downstream to the filter assembly and is adapted to condense the vapor stream into bio-oil.

Abstract: A photocatalytic air purifier (10) is provided which includes a tubular housing (1) having an inner and an outer wall, a central axis (A), a first end (2) having a centrally located air intake nozzle (4), a second end (5) having at least one air exhaust port (6), an air exhaust plenum (11) between the inner housing wall and a radial porosity medium (12), the porosity medium (12) extending radially and axially about the axis, and a housing central portion (13) defined by an interior perimeter of the radial porosity medium (12), the central housing enclosing an ultraviolet lamp (20) and a packing medium (30), the packing medium (30) extending radially and axially about the lamp (20) and comprising a plurality of spiral wound filaments (32) coated with a photocatalytic film.
