NOx Selective Catalytic Reduction over Pt Supported Catalyst Promoted by Zeolite and CeO2-ZrO2

The emission control of NOx in exhaust gases is one of the greatest engineering challenges to extend the practical and commercial application of diesel and lean burn engines. One solution is selective NOx reduction using hydrocarbons in an oxidizing atmosphere. We mainly focused on catalytic reactions under temperature excursion because of the resemblance to conditions prevailing in real automo...

Low temperature selective catalytic reduction of NOx with NH3 over Mn-based catalyst: A review

The removals of NOx by catalytic technology at low temperatures (100–300 °C) for industrial flue gas treatment have received increasing attention. However, the development of low temperature catalysts for selective catalytic reduction (SCR) of NOx with ammonia is still a challenge especially in the presence of SO2. The current status of using Mn-based catalysts for low temperature SCR of NOx wi...

CFD modeling for selective formation of propylene from methanol over synthesized Mn-substituted MFI metallosilicate catalyst

The high silica Mn-substituted MFI metallosilicate catalyst with Si/Al molar ratio of 220 and Si/Mn molar ratio of 50 was successfully synthesized by hydrothermal method. The catalyst sample was appropriately characterized by XRD, FE-SEM, EDX and BET techniques. The Mn-substituted MFI metallosilicate has not been reported as the potential catalyst for the methanol to propylene (MTP) reaction. T...

Selective formation of propylene by hexane cracking over MCM-68 zeolite catalyst.

Dealumination of MCM-68 zeolite with MSE topology enhanced the selectivity to propylene (45-50%) and durability to coke formation during hexane cracking, regardless of the reaction temperature, which is attributed to the control of the position and density of acid sites originating from the framework Al atoms.

Investigation of selective catalytic reduction impact on mercury speciation under simulated NOx emission control conditions.

Selective catalytic reduction (SCR) technology increasingly is being applied for controlling emissions of nitrogen oxides (NOx) from coal-fired boilers. Some recent field and pilot studies suggest that the operation of SCR could affect the chemical form of mercury (Hg) in coal combustion flue gases. The speciation of Hg is an important factor influencing the control and environmental fate of Hg...
