A series of binary Mn-based materials (Fe-MnOx, Cu-MnOx, Cr-MnOx, and Mo-MnOx) were prepared by the coprecipitation method, mechanism for elemental mercury (Hg0) removal Cr-MnOx in absence presence SO2 was investigated. The physicochemical structure properties fresh as well spent samples characterized methods N2 physisorption, XRD, SEM-EDS, FTIR, H2-TPR, XPS, TPD. experiment results revealed that loading Cr into/onto MnOx yielded above 90% Hg0 efficiency at 120 °C. However, appearance would...
The composition of low calorific value synthesis gas varies greatly depending on the raw material and processing technology, which makes combustion extremely complicated. three mechanisms GRI-Mech 3.0, Li-Model, FFCM-Mech are used to numerically simulate CH4/CO/H2/N2 air premixed by using ANSYS CHEMKIN-PRO. numerical simulation is calculation laminar flame velocity adiabatic temperature at an initial 298 K, equivalence ratio 0.6–1.4, pressure 0.1–0.5 MPa, discussing through thermodynamics...
The suppressing effects of inert nanoparticles on methane-air explosion, in an obstructed chamber with internal dimensions 150 mm × 500 mm, were experimentally investigated. To this end, the flame behaviors presence obstacles as well overpressure transients during explosions and without compared. Additionally, density, diameter, material analyzed well. results showed that deflagrating remains generally light blue if are added. In particular, obstacle interaction may enhance suppression...
Aimed at reducing the occurrence of gas explosion accidents, this work explored mechanism and effect ultrasonic water mist suppression on explosion. On basis EDC combustion model, experimental numerical results are compared verified. It shows that flame temperature, propagation velocity, maximum pressure obviously decreased when is added into pipeline, descending proportion increases with increment concentration, which implies can effectively restrain The error time velocity within 10%,...
In this paper, the effects of different ignition positions and equivalence ratios on explosion characteristics syngas in a half-open Hele-Shaw duct were investigated. The points are set at distances 0 500 mm from closed end. Moreover, research range ratio is 0.8-1.2. experimental results indicate that influence flame front structure dynamic propagation. When position end, undergoes several typical propagation stages before eventually reaching open end duct. time required by to reach...
Garbage and biomass contain more chlorine, which reacts with H2 to form HCl gas during combustion or gasification, resulting in corrosion of metal walls. In this paper, based on the chlorine mechanism Ansys Chemkin-Pro, laminar characteristics H2/Cl2 are simulated different diluents CO2/N2 under an initial temperature 298 K, equivalence ratio range 0.6-1.4, pressure 0.1-0.5 MPa. The results show that burning velocity decreases significantly increase dilution ratio, effect diluent CO2 is...
The numerical simulation model of coal gangue brick tunnel kiln system in one mine was established to study the waste heat recovery. gas flow and transfer studied. temperature distribution cangue analyzed. Simulation results show that layout bricks has certain impact on optimizing can improve efficiency utilization.
The catalytic combustion characteristics of a hydrogen–air mixture inside microtube were investigated numerically and experimentally. Numerical simulations with detailed gas-phase surface reaction mechanisms investigated. Combustion for different models the influence wall thermal conductivity, inlet velocity, tube diameter, on reactions are discussed. computational results indicate that restrains combustion. higher temperature gradient low conductivity promotes upstream in distribution. can...
