Apparatus for a photochemical reaction

Claim 2

Apparatus for photochemically reacting a selected fluid comprising: (a) a hollow container, said container comprising a first lower section containing a volume of the selected fluid and a second upper section having at least one light transmitting wall; (b) a shaft supported for rotation in said container; (c) a plurality of porous support disks mounted on said shaft so that a first portion of each support disk extends into said lower container section and a second portion of each support disk extends into said upper container section; (d) webbing means attached to each of said support disks, said webbing means comprising a multiplicity of high surface area fibers suitable for attaching said fluid and having a diameter of about 1/8 inch or less; (e) a light source located adjacent said light transmitting wall, said light source emitting radiation of a selected wave length for exciting selected molecules of said fluid; and (f) means for rotating said shaft so that portions of said webbing means are sequentially immersed in the volume of fluid contained in said lower container section and then moved out of said fluid volume and into said upper container section whereat said fluid is exposed to radiation from said light source.

Claim 3

The apparatus according to claim 1 wherein the multiplicity of fibers are in the form of fiberglass.

Claim 4

The apparatus according to claim 1 wherein the multiplicity of fibers are in the form of ceramic material.

Claim 5

The apparatus according to claim 1 wherein the multiplicity of fibers are in the form of a polyester.

Claim 6

The apparatus according to claim 1 wherein said light source comprises a source of ultraviolet light.

Claim 7

Apparatus for photochemically reacting a selected nutrient fluid with a selected photometabolic microorganism suitable for converting a selected component of the nutrient fluid into a selected chemical, said apparatus comprising: (a) a hollow container, said container comprising a first lower section containing a volume of the selected nutrient fluid and a second upper section having at least one light transmitting wall; (b) a shaft supported for rotation in said container; (c) a plurality of porous support disks mounted on said shaft so that a first portion of each support disk extends into said lower container section and a second portion of each support disk extends into said upper container section; (d) webbing means attached to each of said support disks, said webbing means comprising a multiplicity of high surface area fibers suitable for attaching said microorganism and having a diameter of about 1/8 inch or less; (e) a light source located adjacent said light transmitting wall, said light source emitting radiation of a selected wave length for photometabolically exciting said microorganism; (f) means for rotating said shaft so that portions of said webbing means are sequentially immersed in the volume of nutrient fluid contained in said lower container section and then moved out of said nutrient fluid volume and into said upper container section whereat said microorganism is exposed to the radiation from said light source, said shaft being rotated at a speed which is below the speed at which the microorganism becomes detached from said webbing while providing exposure of the microorganism and the selected nutrient fluid component for a time period sufficient to produce a satisfactory chemical yield; (g) a discharge port for the selected chemical, and (h) means for removing the selected chemical from said container through said discharge port.

Claim 8

Apparatus for photochemically reacting a selected nutrient fluid with a selected photometabolic microorganism suitable for converting a selected component of the nutrient fluid into a selected chemical, said apparatus comprising: (a) a hollow container, said container comprising a first lower section containing a volume of the selected nutrient fluid and a second upper section having at least one light transmitting wall; (b) a shaft supported for rotation in said container; (c) a plurality of porous support disks mounted on said shaft so that a first portion of each support disk extends into said lower container section and a second portion of each support disk extends into said upper container section; (d) webbing means attached to each of said support disks, said webbing means comprising a multiplicity of high surface area fibers suitable for attaching said microorganism and having a diameter of about 1/8 inch or less; (e) a light source located adjacent said light transmitting wall, said light source emitting radiation of a selected wave length for photometabolically exciting said microorganism; (f) means for rotating said shaft so that portions of said webbing means are sequentially immersed in the volume of nutrient fluid contained in said lower container section and then moved out of said nutrient fluid volume and into said upper container section whereat said microorganism is exposed to the radiation from said light source, said shaft being rotated at a speed which is below the speed at which the microorganism becomes detached from said webbing while providing exposure of the microorganism and the selected nutrient fluid component for a time period sufficient to produce a satisfactory chemical yield; (g) a discharge port for the selected chemical, and (h) means for removing the selected chemical from said container through said discharge port.

Claim 9

The apparatus according to claim 6 wherein said light source comprises a source of infrared light.

Claim 10

The apparatus according to claim 6 wherein said support disks include a hollow tube having a plurality of holes therein for intaking the selected fluid and the selected microorganism when said hollow tube is rotated through said first lower container section and for evenly distributing the selected fluid and the selected microorganism over said high area fibers when said hollow tube is rotated through said second upper container section.
