# Commission Implementing Decision (EU) 2017/2117 of 21 November 2017 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the production of large volume organic chemicals (notified under document C(2017) 7469) (Text with EEA relevance), Division BAT 15:: In order to increase resource efficiency when using catalysts, BAT is to use a combination of the techniques given below.

Extent: E+W+S+N.I.

Technique
Description
a.
Catalyst selection
Select the catalyst to achieve the optimal balance between the following factors:
catalyst activity;
catalyst selectivity;
catalyst lifetime (e.g. vulnerability to catalyst poisons);
use of less toxic metals.
b.
Catalyst protection
Techniques used upstream of the catalyst to protect it from poisons (e.g. raw material pretreatment)
c.
Process optimisation
Control of reactor conditions (e.g. temperature, pressure) to achieve the optimal balance between conversion efficiency and catalyst lifetime
d.
Monitoring of catalyst performance
Monitoring of the conversion efficiency to detect the onset of catalyst decay using suitable parameters (e.g. the heat of reaction and the CO2 formation in the case of partial oxidation reactions)
