This work reports an experimental investigation on the morphology and kinetics of CO2 hydrate formation in presence sodium dodecyl sulfate (SDS). The experiments were conducted at 277.15 K 3.5 MPa, quantity SDS varies from 0 to 3000 ppm. "wall climbing" phenomenon was observed, growth above gas–liquid interface found become stronger as concentration increased 300 indicates that promoting effect enhanced with increase concentration. largest gas consumption for solutions obtained 1500 ppm...
Single-layer and high-quality graphene was synthesized over Cu foil by atmospheric pressure chemical vapor deposition (CVD) without additionally introducing H2 gas during the growth time. We compared surface morphology evolution as a function of time, with supply AFM, SEM, EBSD, Raman spectroscopy. The comparison results suggested that absence time caused orientated wrinkles, small grain size, more boundaries on surface, well high quality rapid rate. cross sectional TEM, HR-TEM, SAED...
The consumption of natural gas is great importance to optimize China's energy structure toward reduced CO2 emissions and projected increase in the next 10 years. Coalbed methane (CBM) a primary unconventional has been recognized as significant resource supplement conventional fossil fuels (oil coal) result its huge potential. It established that hydrate-based separation promising method for purification low-concentration coalbed (LCCBM). In this work, research on CH4 from LCCBM conducted by...
Abstract Bilayer graphene ribbons (GRs) hold great promise for the fabrication of next‐generation nanodevices, thanks to unparalleled electronic properties, especially tunable bandgap in association with twist angle, ribbon width, edge structure, and interlayer coupling. A common challenge manufacturing bilayer GRs via templated chemical vapor deposition (CVD) approach is uncontrollable dewetting micro‐ nano‐scaled patterned metal substrates. Herein, a confined CVD synthetic strategy GR...
Cocombustion with biomass tar is a potential method for NO reduction during fossil fuel combustion. In this work, the molecular dynamic based on reactive force field was used to study by phenol, which typical model compound. Results indicate that phenol undergoes significant decomposition at 3000 K, resulting in formation of small fragments accompanied generation large molecular, network-structured soot particles. At higher temperatures (3500 K), morphology produced from certain degree...
Abstract During rapid load increase and decrease in circulating fluidized bed (CFB) units, the presence of a large amount material, including incompletely combusted carbon residue reacted calcium‐based desulphurizers, affects both change rate pollutant emissions boiler. Therefore, rational utilization active stock within boiler plays an important role improving heat release increasing response rate. Using 350 MW supercritical CFB as research object, numerical simulations were conducted on...
The influence of cyclopentane (CP) on methane separation from low-concentration coal mine gas (30% CH4, 60% N2, and 10% O2) by hydrate formation was investigated in the present work. Overpressure used as driving force. Experiments were carried out at 286.6 K (2.0–5.0) MPa, concentration fixed 7.0 wt %. experimental results indicated that uptake increased with increase force, but recovery decreased A ∼ 6% higher obtained under low force ΔP = 1.5 MPa compared to presence tetra-n-butyl ammonium...
Fringe projection profilometry (FPP) is widely used in the 3-D noncontact measurement. In FPP, one of most important steps obtaining absolute phase through fringe orders and wrapped phase. The existing methods usually acquire independently. Therefore, more patterns are needed to project onto object, which decreases measuring speed a lot. We propose an inner shifting-phase method that codes into same four patterns. With unwrapping algorithm, we obtain simultaneously, number required proposed...
In the present work, an adsorption–hydrate hybrid process was employed to enhance separation of CH4 from a 30 mol % CH4/60 N2/O2 gas mixture in presence pulverized coal particles. The incipient hydrate equilibrium conditions for hydrates formed this CH4/N2/O2 were measured 1.0 tetrahydrofuran (THF) and reported. Then, characteristics efficiency, uptake, rate consumption studied at different saturations particles THF. experiments carried out batch operation with initial pressure fixed 3.6...
