The appraisal committee is composed of 11 experts including Jin Yong, Wang Xieqing, and Yang Qiye, academicians of the Chinese Academy of Engineering.

75em; word-wrap: break-word ;">Paraxylene is an important organic chemical raw material.

According to Li Jun, deputy secretary and general manager of Yanchang Petroleum Group Refining and Chemical Company, China consumed 24 million tons of paraxylene in 2017 , imported 14 million tons , and its dependence on foreign countries exceeded 58%.
Traditional p-xylene production mainly uses straight-run, hydrocracked naphtha or ethylene pyrolysis gasoline as raw materials, and is extracted through the aromatics combined device matched with the refining unit.

75em; word-wrap: break-word ;">According to reports, the 10,000-ton industrial test device was commissioned in April this year to open up the process, and completed the 72-hour industrial test assessment in September.

The assessment results showed that the conversion rate of toluene per pass was 26.
42%; the conversion rate of methanol per pass was 93.
