Abstract: Low Pt content SKI-110 catalyst，an ethylbenzene dealkylation C8 aromatics isomerization catalyst，developed by Research Institute of Petroleum Processing has been applied in a large integrated complex. The performance test results show that low Pt content SKI-110 catalyst exhibits good catalytic performance，the isomerization activity of para-xylene reaches 23.04%，the conversion of ethylbenzene reaches 70.40% and the xylene yield is up to 98.00%. Lower production cost for para-xylene and less energy consumption of the unit are achieved.
