Jinling Petrochemical Company recently used SCC’s toluene disproportionation catalyst in its dismutation and isomerization section of PX units. After the application, the production has been increased and the cost has reduced. The production of aromatic hydrocarbon is increased 200 tons daily and the paraxylene is expected to increase by more than 3% daily. Consequently, the catalyst brings added benefits to the company of more than 10 million yuan per month. The loss of aromatic hydrocarbon can be reduced from 6.1% to 2.7%.
