Development of BEACON technology. Quarterly report, April-June 1982

Description: The BEACON process involves the catalytic deposition of a highly reactive form of carbon from a gas stream which contains carbon monoxide. The carbon-depleted gas is combusted with air to produce power, and the carbon is reacted with steam to produce methane or hydrogen. Experiments were continued this quarter with the objective of improving the carbon deposition efficiency using a Paraho retort off-gas mixture. Analysis has shown that the use of the Paraho off-gas to make hydrogen would be att… more

Design of a diesel exhaust-gas purification system for inert-gas drilling

Description: To combat the serious oxygen corrosion of drill pipe when a low density drilling fluid (air or mist) is used in geothermal drilling, a system has been designed that produces an inert gas (essentially nitrogen) to be substituted for air. The system fits on three flatbed trailers, is roadable and produces 2000 scfm of gas. The projected cost for gas is slightly less than $2.00 per thousand standard cubic feet.

Future aircraft and potential effects on stratospheric ozone and climate

Description: The purpose of this study is to extend the recent research examining the global environmental effects from potential fleets of subsonic and supersonic commercial aircraft. Initial studies with LLNL models of global atmospheric chemical, radiative, and transport processes have indicated that substantial decreases in stratospheric ozone concentrations could result from emissions of NO{sub x} from aircraft flying in the stratosphere, depending on fleet size and magnitude of the engine emissions.

The quest for greenhouse-constrained technologies amid other concerns for environment and energy

Description: As we approach the 21st century, sentiments run high in the US for improved air quality in our cities and for a more secure energy future, hopefully to be manifest in lesser dependence on foreign supplies of oil. These sentiments are reflected in intense political activity on both the federal and state levels to enact legislation that will help alleviate both problems. At the same time though, the recent emergence of awareness of a threat of global warming due to ever increasing emissions of gr… more

Energy from true in situ processing of Antrim Shale: extraction trials in an explosively fractured site

Description: Three in situ energy extraction trials were conducted at The Dow Chemical Company's oil shale site, in Michigan's Sanilac County, near the town of Peck. Here the Antrim shale layer occurs between 1200 and 1400 feet underground. The trials began on October 14, 1979, and ended on April 1, 1980. The three trials, lasting 7, 60 and 17 days respectively, were conducted in a formation prepared by explosive fracturing. Ignition energy was generated with a methane burner. Some energy in the form of a d… more

NO/sub 2/ levels in diesel exhaust

Description: The safe operation of diesel-powered equipment in underground mines is predicated on there being sufficient ventilation to dilute the exhaust such that none of the toxicants in the dilute mixture exceed allowable levels. In order to determine the ventilation requirement for an engine, it is necessary to measure levels of the various toxicants in the exhaust. Measurements in the past typically either have excluded nitrogen dioxide or have not provided information on nitrogen dioxide specifically… more

Development of BEACON technology. Quarterly report, January-March 1982

Description: The BEACON process involves the catalytic deposition of a highly reactive form of carbon from a gas stream which contains carbon monoxide. The carbon-depleted gas is combusted with air to produce power, and the carbon is reacted with steam to produce methane or hydrogen. Process conditions favoring the production of hydrogen were explored this quarter. Excess steam was found to suppress methane formation, and reduction of catalyst methanation activity was demonstrated. The effect of carbon load… more

Durability testing at one atmosphere of advanced catalysts and catalyst supports for automotive gas turbine engine combustors. Part 1

Description: Studies were conducted to experimentally demonstrate the durability catalysts and catalyst supports in a combustion environment. A test of 1000 hours duration was completed with two catalysts, using No. 2 diesel fuel and operating at catalytically supported thermal combustion conditions. This atmospheric pressure durability test was conducted, using an air preheat temperature of about 640/sup 0/K and a reference velocity of about 14 meters/second. The adiabatic flame temperature of the fuel/air… more

Ancillary effects of selected acid deposition control policies

Description: NAPAP is examining a number of potential ways to reduce the precursors (sulfur dioxide and nitrogen oxides) to acid deposition. However, the policies to reduce acid deposition will have other physical, biological and economic effects unrelated to acid deposition. For example, control policies that reduce sulfur dioxide emissions may also increase visibility. The effects of an acid deposition policy that are unrelated to acid deposition are referred to as ''ancillary'' effects. This reserch iden… more

Improving the energy efficiency of residential clothes dryers

Description: An experimental study on energy efficient electrical domestic clothes dryers is presented. A literature survey was performed and four basic energy saving techniques were identified: (1) reduced air flow rate and heater input, (2) recirculation of a portion of the exhaust air back into the clothes dryer, (3) heat recovery, utilizing an air-to-air heat exchanger, and (4) 100% recirculation of air through the dryer and a heat pump to condense water out of the air. Reduced air flow rate and heater … more

Analytical and experimental studies of heat pipe radiation cooling of hypersonic propulsion systems

Description: Preliminary, research-oriented, analytical and experimental studies were completed to assess the feasibility of using high-temperature heat pipes to cool hypersonic engine components. This new approach involves using heat pipes to transport heat away from the combustor, nozzle, or inlet regions, and to reject it to the environment by thermal radiation from an external heat pipe nacelle. For propulsion systems using heat pipe radiation cooling (HPRC), it is possible to continue to use hydrocarbo… more

Investigative study of engine limiting

Description: An experimental study was conducted to determine the effect of cylinder cut-out or ''engine limiting'' on fuel consumption and exhaust emissions for a current technology V-type 8-cylinder engine. Increases in energy conversion efficiency while operating with only 4 cylinders ranged from 10 to 40% compared to operation with 8 cylinders at the same power outputs. The speeds and loads chosen were representative of those required to operate a 4,500-lb vehicle at speeds up to 60 mph. Hydrocarbon emi… more

Characterization and Research Investigation of Methanol and Methyl Fuels. Final Progress Report

Description: Work on several aspects of using pure methanol as an alternate fuel are reported. A stock (OEM) Pinto engine mounted on a dynamometer was used to compare methanol with Indolene in terms of power, efficiency, and emissions for a variety of speeds and loads. Although the engine was designed for use with gasoline, it was found that methanol was generally superior in power, thermal efficiency and reduced emissions with the exception of aldehydes. Three different fuel metering systems were tested fo… more

Single cylinder spark ignition engine study of NO and NO/sub 2/ emissions for methanol, iso-octane and nitrogen doped methanol with emphasis on measurement technique

Description: NO and NO/sub 2/ emissions from a single cylinder CFR engine were measured as a function of fuel air equivalence ratio for the spark ignited combustion of methanol, iso-octane and nitrogen doped methanol. In all cases, no NO/sub 2/ was detected for fuel-rich or stoichiometric combustion, while significant amounts of NO/sub 2/ were found for fuel-lean combustion. The exhaust system and exhaust sampling system were throughly tested for NO and NO/sub 2/ conversions, NO/sub 2/ to NO conversions and… more
