19.8 REDUCTION OF ALDEHYDES AND KETONES TO …

Catalytic hydrogenation is less important for the reduction of carbonyl groups than it once was because of the modern use of hydride reagents. It is usually possible to use catalytic hydrogenation for the selective reduction of an alkene double bond in the presence of a carbonyl group. Palladium catalysts are particularly effective

Diesel Exhaust Fluid (DEF) Q & A - Cummins Filtration

What is Selective Catalytic Reduction (SCR)? A. SCR is a technology that uses a urea based diesel exhaust fluid (DEF) and a catalytic converter to significantly reduce oxides of nitrogen (NOx) emissions. SCR is the leading technology being used to meet 2010 emission regulations. Q. How does an SCR system work?

32 Urea Fact Sheet - Incitec Pivot Fertilisers

Selective Catalytic Reduction (SCR) Urea. UAN is used as a liquid nitrogen fertiliser. It is marketed by Incitec Pivot Fertilisers as EASY N. SCR Urea is used as an exhaust-scrubbing agent in heavy-duty diesel motors, to improve performance and reduce nitrous oxides (NO x) emissions. NO x contributes to the formation of smog.

AP42 8.8 Nitric Acid Production

Catalytic reduction can be used in conjunction with other NO x emission controls. Other advantages include the capability to operate at any pressure and the option of heat recovery to provide energy for process compression as well as extra steam. Catalytic reduction can achieve greater NO x reduction than extended absorption. However, high fuel ...

3 With optimized conditions for the photochemical coupling between 2 and 3 in hand, we implemented a one-pot sequence for the direct C–H alkylation of tert-butylbenzene 1 (Figure 2c). This was accomplished by addition of 1 to a mixture of dibenzothiophene (DBT) S-oxide and trifluoromethanesulfonic anhydride in CH 2Cl 2, forming 2 in situ.The crude mixture was treated …
