Gasoline upgrading technology is another unique technology developed by our company. It is a new process of cracking, stacking, isomerization, cyclization, aromatization, dehydrogenation and other chemical reactions of gasoline components under the action of catalyst, using atmospheric straight run gasoline as raw material in non hydrogen state, which can greatly improve the octane number of gasoline. The process has new projects with less investment and quick effect, which is very popular with small and medium-sized refineries.
