US Patent:

20080009055, Jan 10, 2008
Filed:

Jan 22, 2007
Appl. No.:

11/656330
Inventors:

John J. Lewnard - Westford MA, US
Assignee:

Greenfuel Technologies Corp. - Cambridge MA
International Classification:

C02F 3/34
C02F 11/02
US Classification:

435262, 4352921
Abstract:

Integrated systems including a photobioreactor system designed to contain a liquid medium comprising at least one species of phototrophic organism therein, and a facility associated with extracting and/or processing oil extracted from mixtures of oil and solid material, such as an oil sands facility, are described. Processes for using a photobioreactor system as part of a gas-treatment process and system able to at least partially remove certain undesirable pollutants from a byproduct gas stream produced by an oil sands facility are also described. Examples of such pollutants that may be removed include compounds contained within combustion gases, e.g., COand/or NO. These pollutants processed with the photobioreactor system, and, in some embodiments, biomass produced with the photobioreactor system may be utilized to produce a fuel source (e.g., biodiesel) and cutting stock for further operation of or use in the oil sands facility. Such uses of certain embodiments can provide an efficient means for recycling carbon, thereby reducing COemissions, fuel, and/or cutting stock requirements for a given quantum of energy produced. In addition, in some cases the photobioreactor can be integrated with a holding pond and waste heat from the oil extraction process can be used to maintain the photobioreactor temperature and/or provide energy for other processes. Accordingly, embodiments described herein can improve the overall environmental and economic profile of the oil sands facility.

US Patent:

49102273, Mar 20, 1990
Filed:

Oct 11, 1988
Appl. No.:

7/255935
Inventors:

Dennis M. Brown - Allentown PA
John J. Lewnard - Emmaus PA
Pradip Rao - Allentown PA
Robert F. Weimer - Allentown PA
Assignee:

Air Products and Chemicals, Inc. - Allentown PA
International Classification:

C07C 2701
US Classification:

518700
Abstract:

The present invention relates to a process for improving reactor volumetric productivity in the production of methanol wherein a synthesis feed gas stream containing hydrogen and carbon oxides is contacted with a catalyst slurry containing greater than about 25 wt % of a powdered copper-containing catalyst having a porosity of from about 30% to 70%. Volumetric productivity is maximized in the process by controlling a single parameter, gas holdup, wherein holdup is maintained within the range of about 14% to 26%.
