It is necessary in the next phase of technical development to carry out an in-depth study on the reaction mechanism, high-activity catalysts, process technology and engineering techniques to further raise the technical level, reduce investment and production cost in a bid to provide technical support for low-cost upgrading of gasoline quality.展开更多
