(Texas A&M University. Libraries, 1986)Producing methane from biomass feedstock by using anaerobic digestion method is a way of providing a renewable source of energy. When a seasonal crop is used as a feedstock in a batch digestion method, storing of the biomass ...
-
(Texas A&M University. Libraries, 1987)The results of this research indicate that [M⁺O⁻] centers (M = Group IA ions) in Group IA/Group IIA oxides are responsible for the catalytic production of CH₃[superscript dot] radicals from CH₄ through hydrogen atom ...
-
(2017-12-08)In this research, the uncertainty of commonly used GHG measurement methods was evaluated using Taylor series uncertainty analysis and a field study was performed to evaluate the feasibility of one of these methods. Taylor ...
-
(2014-10-31)One of the most pressing technical challenges in the production of biofuels from biomass is the unavailability of economical processes to remove 30-45% (w/w) of the oxygen that is present in biomass-derived oxygenates. The ...
-
(2014-08-12)Marine gas seeps and accidental marine oil spills are sources of methane (CH_(4)) to the ocean, and potentially to the atmosphere, though the magnitude of the fluxes and dynamics of these systems are poorly defined. For ...
-
(2015-09-30)Methane (CH4) originating from thermogenic (e.g. seafloor seeps) and biogenic sources (e.g. methanogenesis) affects the distribution of methane concentrations at varying depths in the ocean. A comprehensive survey of CH4 ...
-
(Texas A&M University, 2004-11-15)A greenhouse study was conducted to investigate the mechanisms causing diurnal variations in methane emission from rice plants (Oryza sativa L.). Methane emission was measured using a closed chamber system on individual ...
-
(Texas A&M University. Libraries, 1982)Methane gas is a highly prized fuel in the world. However, the low burning velocity and instability of a flame creates some problems for the burning of natural gas. By applying an electric field, a means may be provided ...
-
(2011-02-22)A new shock tube targeting low temperature, high pressure, and long test times was designed and installed at the Turbomachinery Laboratory in December of 2008. The single-pulse shock tube uses either lexan diaphragms or ...
-
(Texas A&M University. Libraries, 1991)Over La2O3 and the transition metal oxide catalysts LiNiO2 and NaMnO4/MgO it was demonstrated that the coupling of the surface-generated gas-phase Ch4 radicals constitutes a major pathway for the formation of C2+ hydrocarbons ...
-
(2017-07-24)Studying the combustion properties of liquid fuels and low vapor pressure fuels is important for power generation, propulsion, and aviation. Determining these properties, requires facilities like heated shock tubes that ...
-
(2022-05-20)The energy-efficient capture and release of gas molecules, mainly carbon dioxide, methane, hydrogen, and small hydrocarbons, has been an area of significant academic and industrial interest due to their relevance for ...
-
(Texas A&M University. Libraries, 1978)The di-π-methane rearrangement has been shown to be of very general scope. During the course of a study designed to broaden the scope of this rearrangement by including a nitrogen atom in the backbone of the di-π-methane ...
-
(2016-07-28)Chemical process design requires mathematical models for predicting thermophysical properties. Those models, called equations of state (EoS), need experimental data for parameter estimation and validation. This work presents ...
-
(2013-05-21)Condensed tannins (CT) are polyphenolic compounds that have demonstrated biological activities in ruminants including suppression of enteric methane (CH4) production, protein binding and suppression of gastrointestinal ...
-
(2018-11-27)Due to the rapid vertical transportation of methane in the ocean, there is a growing concern regarding the contribution of natural gas seepage to the global atmospheric greenhouse gas budget. Hence, it is essential to ...
-
Radiochemical Transformation of High Pressure Methane under Gamma, Electron, and Neutron Irradiation (2014-05-01)The chemical effects of irradiation on high pressure methane and noble gas mixtures were investigated using gamma, electron beam, and neutron irradiation sources. The gamma source used was the La-140 source from the Nuclear ...
-
(2012-10-19)The ocean is both a source and a sink for atmospheric methyl bromide (CH3Br) and methyl chloride (CH3Cl). It plays a significant role in their global biogeochemical cycling. In response to the Montreal Protocol, the ...
-
(2016-05-24)In the U.S., gastrointestinal fermentation from cattle is estimated to account for approximately 25% of total anthropogenic related methane (CH4) emissions. In addition, 2-8% of gross energy consumed by cattle is lost in ...
-
(2019-11-08)Methane-derived carbonates occur in siliciclastic settings globally and precipitate from bicarbonate derived from methane oxidation. Methane-derived carbonates, which occur from the Archean to the present, take diverse ...
