Sentence examples for selectivity catalyst from inspiring English sources

CrHMA was the most active (64.9% conversion) and selective (80% α-tetralone selectivity) catalyst, but developed metal leaching due to its amorphous pore walls.

The efficiency of different carbon structures (macro/micro) was investigated over selectivity catalyst.

The study showed that that the RDR process is the superior process in terms of DAA-MO selectivity, catalyst productivity and separation costs.

Quantities such as product distribution, selectivity, catalyst lifetime, TON and activity were used in comparing and evaluating the efficiency of the precatalyst.

In recent years, the development of efficient artificial photocatalysts for CO2 reduction has attracted much attention; however, the product selectivity, catalyst stability and catalytic activity are far from the requirements for commercial consideration.

In recent years, development of efficient artificial photocatalysts for CO2 reduction has attracted much attention; however, the product selectivity, catalyst stability and catalytic activity are far from the requirements for commercial consideration.

Compound 2, which does not require any alcohol, was even more iso-selective at room temperature (Pi=0.82±0.02) and represents, to our knowledge, the highest iso-selectivity catalyst reported, excluding the aluminium salen complexes.

The high p-xylene-selectivity catalyst modified further with Pt, Pd, Co, Ni metal demonstrated excellent stability, even after 100 400 h on stream, and the selectivity for p-xylene of more than 98.3% with toluene conversion of 20.0% was achieved.

32 In the course of these investigations it was also shown that the presence of both ammonium groups was crucial to ensure high selectivities; catalysts containing only one ammonium group performed with only very poor selectivity.

Issues related to the role of catalyst-topology, acidity properties, reaction parameters and their effects on catalytic activity, selectivity and catalyst lifetime have been critically covered.

To be concluded, the PSD has a significant influence on product selectivity of catalyst.
