Testing and research catalytic processes

​
ARSKA Technologies offers solutions in testing of adsorbents and catalysts for compliance with manufacturer-declared parameters for the process. The aim of testing is to determine optimal parameters of the process.
​
Testing includes the following principle steps:
​
1. Testing of catalysts on the pilot units that imitate the reactor of a refinery plant.
​
2. Carrying out the analitical research of the raw feedstock components and the products of catalytic reaction.
 
3. Estimation optimal parameters of the process that would allow maximal product output.
​
In the research procedures of the catalyst properties and hydrocarbon mixture composition specialysts of ARSKA Technologies use the top analytical equipment  that provide high analysis precision and speed.
