Is Syamcat YJ 18G catalyst pre-sulfided type or non-sulfided type?

HDS catalyst Syamcat YJ 18G should be sulfided(convert oxidation state of Co and Mo etc active component into sulfurized state) to increase the activity, stability and selectivity.

●Non-sulfided: We usually suggest non-sulfided HDS catalyst to help customers to save cost. Sulfuration procedure can be carried out and finished soon during stable running(after startup), based on the sulfur content of feedstock. 

●Pre-sulfided: Can be offered also if necessary(sulfuration procedure should be done before loading of the catalyst). We can finish the sulfuration procedure on our facilities.
