US Patent:

60397748, Mar 21, 2000

Filed:

Dec 26, 1996

Appl. No.:

8/774185

Inventors:

Frederick G. McMullen - Gwynedd Valley PA
Dillon G. McMullen - Irma WI
Roger B. McMullen - Irma WI

International Classification:

C10G 904
B01F 302

US Classification:

48102A

Abstract:

A self-sustaining system for converting organic waste feedstreams into usable solid and gas end products includes a plurality of interconnected retorts, an apparatus for flash pyrolyzing the feedstream to form intermediate gas and solid products, a source for introducing a water spray to refine and cool the intermediate products, a device for separating the gas product from the solid product and a device for regenerating, and thereby further refining, the solid product. In a self-sustaining process, wastes which would otherwise be landfilled are converted to an activated carbon product and a combustible gas mixture of hydrogen, carbon monoxide, and lower hydrocarbons.

US Patent:

43211500, Mar 23, 1982

Filed:

Dec 7, 1979

Appl. No.:

6/101128

Inventors:

Frederick G. McMullen - Ambler PA

International Classification:

C02F 1112

US Classification:

210769

Abstract:

The process disclosed includes treating settled sludge and/or organic debris recovered from a wastewater treatment system and thermally converting the treated material and/or comminuted organic solid wastes separately or in combination into steam combustible gas, residual tars and oils and other energy by-products which are recycled as heat for increasing the thermodynamic efficiency of the process. The process further includes cleaning the combustible gas which is provided during the thermal conversion so that the gas is suitable for driving gas engine or gas turbine generators and the like.

International Classification:

C10B 106

US Classification:

202109

Abstract:

Pyrolytic apparatus for the rapid and efficient thermal dissociation of matter is disclosed. The apparatus includes a concentric tubular arrangement of high thermal conductivity in a heat sink configuration; inlet members for heat and feedstock; outlet members for solids, gases and heat exhaust; and a plurality of annular passages through which heat is brought into heat transfer relationship with an interior pyrolytic retort section for the dissociation of matter conveyed therein into solid, liquid and gaseous by-products. Provisions are made for the separate liberation of steam produced by the simultaneous interfacing of superheated steam and product gas during pyrolytic decomposition of high moisture content feedstocks. Additional hydrocarbons from the product gas evoluted in the pyrolytic retort section are provided by diversion of the gas to an annulus flanked on either side by adjacent annuli conveying the heat source supply to exit. Residual carbon, the by-product of the dissociation, is continuously expelled from the pyrolytic retort section of the apparatus.

Inventors:

Frederick G. McMullen - Gwynedd Valley PA

International Classification:

C02F 1112

US Classification:

210769

Abstract:

The process disclosed includes treating settled sludge and/or organic debris recovered from a wastewater treatment system and thermally converting the treated material and/or comminuted organic solid wastes separately or in combination into steam, combustible gas, residual tars and oils and other energy by-products which are recycled as heat for increasing the thermodynamic efficiency of the process. In one embodiment of the invention the process includes cleaning the combustible gas which is provided during the thermal conversion, with the clean gas driving a heat engine such as a gas engine or gas turbine generator or the like. In another embodiment of the invention the gas drives the heat engine without the above described benefit of the aforenoted cleaning. In either case, the high temperature exhaust from the described heat engine is fed back for supporting the thermal conversion of the organic materials in a boiler/pyrolyzer, refractory furnace or a separate retort having its own heat chamber, connected directly to the exhaust manifold of the heat engine.
