Abstract: Since July 2021,the 80 000 tons per year isomerization unit of Refining and Chemical Complex of PetroChina Yumen Oilfield Company has encountered the situation that the octane number of the product decreases and the isomerization reaction weakens.Through regeneration within the unit,the catalyst restores its activity,and the octane number of the isomerized product rise to 85.
