Benefits from catalyst evaluation

For Thaioil, the selection of the most suitable hydrotreating catalyst can lead to estimated cost saving of 15 million baht/year/reactor.

Objectives of catalyst evaluation program

To evaluate catalytic performance of hydrotreating catalyst in terms of the Start of Run (SOR) temperature (ºC) and deactivation rate (ºC/month). Essential process parameters can also be determined; for examples, mass balance, hydrocarbon yields, and so forth.

Exemplary results

Catalytic activity comparison

Start of run (SOR) temperature at targeted sulfur

By using the above graph, SOR temperature is considered the temperature at a targeted sulfur is produced.

Catalyst deactivation rate (ºC/month)

Catalyst deactivation is determined as the rate of temperature increment per month (ºC/month) in order to keep the product at targeted sulfur.

Hydrocarbon yields (C1 – C20, C20+)

Mass balance

Hydrogen consumption
