Humic acid (HA) is widely used for soil quality improvement, yet little known how bacterial communities, especially common and rare bacteria, respond to HA amendment, which crucial understand biodiversity function in agroecosystem. Therefore, a manipulated microcosm experiment with gradient of amendment was conducted unveil this. The results showed that taxa had similar patterns species richness, while exhibited higher turnover, caused their structural dissimilarity. Common wider niche...
The reason that the stoichiometry of gas to water in artificial hydrates formed on porous materials is much higher than nature still ambiguous. Fortunately, based our experimental thermodynamic and kinetic study hydrate formation behavior with classic ordered mesoporous carbon CMK-3 irregular activated combined density functional theory calculations, we discover a microscopic pathway materials. Two interesting processes including (I) replacement adsorbed surface by (II) further pore...
Nitrogen (N) deep placement has been found to reduce N leaching and increase use efficiency in paddy fields. However, relatively little is known how bacterial consortia, especially abundant rare taxa, respond placement, which critical for understanding the biodiversity function of agricultural ecosystem. In this study, Illumina sequencing ecological models were conducted examine diversity patterns underlying assembly mechanisms taxa rice rhizosphere soil under different fertilization regimes...
A hydrate slurry transport technology based on risk control methods is an important technical means to solve the blockage of multiphase pipelines and guarantee safety efficiency exploitation petroleum resources in deep-water. It foundation for industrial promotion this adequately understand flow characteristics, especially influence microbehavior particle size its distribution. This research establishes a kinetic model aggregation (KMHA) that developed reflect complex physical processes...
The Himalayan alpine canyon area is characterized by complex engineering geological conditions and abnormal internal external dynamic processes. Severe slope disturbance disasters can be caused disturbances. In this study, field investigations theoretical analyses were performed to determine the formation mechanism, spatial distribution law, controlling factors of in areas. A total 396 identified within scope 2,800-km survey line. geographic information system mathematical statistical...
Utilizing dynamic adsorptive method, the static equilibrium sorption data of CO2/CH4 binary gases with four different concentrations on CMK-3 present water were collected. Compared similar system only in bulk water, it was found that whole process considerably complex, which mixed gas hydrate formation competitive adsorption. The comprehensive discussions about wet have been here generating reasonable conclusions. selectivity also calculated as important support for separation by using...
Equilibrium data of ethylene sorption on activated carbon in the presence water are measured for near-critical temperatures. The isotherms indicate formation hydrates. Hydrate is a compressed state gases and receives interest gas storage or separation, pores may reach complete conversion show better dynamic behavior. It presently shown that hydrate pressure at above-critical temperatures observed considerably less than reported media. Both molar ratio to equilibrium enthalpies sub-...
A method to separate a gaseous mixture of nitrogen and methane by exploiting the difference between hydrate-formation pressures has been developed enrich concentration in low-quality coal-bed methane. The equilibrium isotherms pure N 2 CH 4 CMK-3, mesoporous carbon material, presence water are measured determine optimal separation parameters. Tetrahydrofuran (THF) was added lower at which gas hydrates formed. containing 50% fed through bed filled with CMK-3 THF solution 5 mmol/g...
The use of hydrate formation in porous media is an effective method for gas storage and separation. equilibrium isotherms CH4 N2 CMK-3, a mesoporous carbon material, were measured under different tetrahydrofuran (THF) concentrations temperatures. higher the temperature required, greater pressure needed, but presence THF significantly reduces pressure. When exists, both form structure II (sII) hydrate; however, amount generation lower than theoretical value. As operating increases, some sII...
Abstract There have been various environmental issues in the treatment and resource utilisation of solid waste livestock poultry industry Gansu Province. Thus, this study, manure cattle, pig, chicken from farms near Lanzhou University Technology City, Province were selected as raw materials for composting using 10 % corn stalk a leavening agent aerobic static composting. This study focused on bacterial, fungal, actinomycetes community succession during underlying microbial degradation...
The low efficiency and unstable gas production of hydrate exploitation have become the difficulties restricting commercial exploitation. In this work, based on geological conditions reservoir in South China Sea, paper establishes a low-permeability heterogeneous reservoirs model multi-layers “hydrate layer/mixed layer/free layer” to analyse effects hot water injection well reservoir. results show that decomposition are lower than those under depressurization due increase pore pressure...
The formation of gas hydrates in porous carbon materials is highly dependent on the potential field pores. ethylene hydrate from water and with different pore-size distributions was investigated at 303 K. pores favourable for when were less than 1.2 nm. By comparison, larger 6 nm, little formed. When pore sizes 2.35 molecules occupied both large (L) small (S) cavities simultaneously. However, greater 2.82 only L occupied. This proven by measuring molar ratio to equilibrium.
