Summary of "Effect of preparation and reaction conditions on the performance of In/H-Beta for selective catalytic reduction of NO with CH."

In/H-Beta catalyst was prepared by optimizing the support, concentration of ion exchange liquid and calcination temperature to investigate the effects of synthesis conditions on catalytic activity of selective catalytic reduction of NO with CH. The results showed that the In/H-Beta catalyst exhibited the superior activity when concentration of exchange liquid was 0.033 M and calcination temperature was 500 °C, the NO removal ratio could reach 97.6%. In addition, reaction conditions could affect the catalytic performance. When O concentration was 10%,
NO ratio was no less than one, space velocity was lower than 23600 h and NO initial concentration was no more than 700 ppm, In/H-Beta could exhibit superior catalytic activity. Moreover, the catalytic performances of In/H-Beta catalysts were discussed after enduring HO or/and SO. This novel strategy could open the door for selective catalytic reduction of NO with CH.

Medical and Biotech [MESH] Definitions

A beta-2 selective adrenergic antagonist. It is used primarily in animal and tissue experiments to characterize beta-2 receptor involvement and identify beta-2 receptors.

A highly selective and specific beta antagonist that is used to characterize beta-adrenoceptors.

RNA that has catalytic activity. The catalytic RNA sequence folds to form a complex surface that can function as an enzyme in reactions with itself and other molecules. It may function even in the absence of protein. There are numerous examples of RNA species that are acted upon by catalytic RNA, however the scope of this enzyme class is not limited to a particular type of substrate.

The region of an enzyme that interacts with its substrate to cause the enzymatic reaction.

Sperm surface proteins involved in sperm-egg fusion. They consist of two subunits, fertilin alpha (ADAM1a) and beta (ADAM2), both of which belong to the metalloprotease-disintegrin protein family. The beta subunit does not have catalytic activity.
