This article also explores the technical measures for maximizing the target products delivered by the gasoline-type and aromatic-type CCR units with respect to the selection of catalysts, the optimization of feedstock and the optimized operating regime.展开更多

Test results had revealed that the low potential aromatic content of the reformer feed and high operating severity were the critical causes leading to high bromine number of the C8^+ aromatics feed for the PX unit and the shortened service life of clay. This article also puts forward the corresponding remedial measures.展开更多
