Appl. No.:

09/848792

Inventors:

Christopher Churchill - Sacramento CA, US
Charles Likes - Yuba City CA, US
Theodore Bauer - Central Point OR, US

International Classification:

E06B001/04
E04C002/38

US Classification:

052/783120, 052/784100, 052/204100, 052/455000, 052/656400

Abstract:

The present invention provides a building material derived from straw, such as rice straw, that has significantly improved fire-resistance properties over traditional cellulose-based materials. In one embodiment, the invention provides a method of fabricating a board from milled rice straw. The milled rice straw is blended with a binder to form a mixture. The mixture is then formed into a mat with sufficient size to achieve a predetermined board thickness and density. The mat is then pressed into the board. In another embodiment, the present invention provides a fire resistant board that includes milled rice straw, a resin binder, and a fire retardant material such as an organic phosphate, zinc borate, aluminum tribydrate, sodium silicate, or even rice hulls.

Appl. No.:

11/294292

Inventors:

Christopher Churchill - Sacramento CA, US

Assignee:

GREENCOR COMPOSITES, LLC - SACRAMENTO CA

International Classification:

C09D 5/20

US Classification:

106002000

Abstract:

The present invention is a fire-retardant wall having a fire-resistance rating of a least two hours and a method of making such a fire-retardant wall. The fire-retardant wall includes a first layer comprising an inner core, typically made of an insulated panel used in construction of buildings, and at least one second layer on each side of first layer, the at least one second layer further comprising at least one fire-resistant board of pressed milled straw, thereby forming the fire-retardant wall having a fire-resistance rating of at least two-hours. The second layer may also include a structural board used as a building panel in construction of buildings and/or an interior wall board used for internal and external walls and ceilings of buildings, wherein such boards are positioned on the exterior side of at least one board of pressed milled straw.

Christopher Churchill - Sacramento CA, US

International Classification:

C10B 53/02
C10L 1/02
C10L 1/18
B01D 5/00

US Classification:

44307, 202109, 201 29, 44436

Abstract:

A system is described that includes a pyrolyzer and a primary condenser. The primary condenser is coupled to the pyrolyzer and configured to receive pyrolytic vapors from the pyrolyzer. The primary condenser is further configured to condense the pyrolytic vapors by contacting the pyrolytic vapors with a condensing liquid, to form a bio-oil component mixture having multiple separated phases. At least a portion of the condensing liquid includes a component that is extracted as a separated stable phase from a second bio-oil component mixture resulting from a prior pyrolysis cycle.

International Classification:

C10B 19/00

US Classification:

201 34, 202108

Abstract:

A fast pyrolizer includes an elongated tubular housing having a feed inlet to receive material, an outlet, and a flow path. The flow path has an internal contact surface extending from the inlet to the outlet. The inlet is to be oriented to a non-vertical relative elevation with respect to the outlet. At least a portion of the internal contact surface directly contacts the material. A heater heats the internal contact surface such that the material is heated via direct thermal transfer from the internal contact surface.

US Classification:

44307, 422187

Abstract:

A system is described that includes a pyrolyzer and a primary condenser. The primary condenser is coupled to the pyrolyzer and includes an input to receive pyrolytic vapors from the pyrolyzer and a solvent. The condenser is further configured to condense the pyrolytic vapors by contacting the pyrolytic vapors with the solvent to form a condensed liquid that exits the primary condenser via an output. A capture vessel receives the condensed liquid from the condenser output. A recirculator couples the capture vessel to the primary condenser input and is configured to receive the condensed liquid from the primary condenser, and to provide at least a portion of the condensed liquid as the solvent in the primary condenser. The solvent from the bio-oil component/solvent mixture is then extracted in a solvent extraction system and returned to the quenching system.
