Purpose. Using mathematical modeling, to assess the feasibility of introducing a Selective Non-Catalytic Reduction (SNCR) system as measure reduce nitrogen oxide emissions from production iron ore pellets. To determine peculiarities using ammonia solution and urea reagents for SNCR process, influence injection these on temperature regime during pellet production, well expected efficiency method...
abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
In markets with strict emission legislations Selective Catalytic Reduction (SCR) has become the industry standard for NOx abatement in heavy-duty vehicles, and therefore modeling control of these systems are vital. Many SCR catalyst models available literature this paper different discussed classified into groups. Two models, based on two most popular classes control-oriented implemented compar...
effects of water on the catalytic performances of movtenbo catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. presence of water induces some structural modif...
Novel 3D flower-like NiMnFe mixed oxides as monolith catalysts prepared by an in situ hydrothermal method show enhanced performance for the selective catalytic reduction of NO with NH(3).
gas diffusion electrode was used for providing better conditions in fuel cell systems for oxygen reduction reaction (orr). because the slow kinetics of the oxygen reduction reaction at the proton exchange membrane fuel cell cathode restricts fuel cell efficiency. to this end, researchers have used platinum-coated carbon. in the present study, due to the reduction of carbon corrosion, zinc oxide...
Biodiesel fuels releases higher NOx emissions than fossil diesel. The Selective Catalytic Reduction (SCR) technique used in the OEM industry is not suitable for application small engines due to back pressure and clogging problems. Non-Catalytic (SNCR) relatively large combustion operations. This study introduces a new design by combining SCR SNCR systems, use low power density diesel engines. s...
