Utilization method of hydrocarbon oil enriched in C4 and C5 alkanes

The invention provides a utilization method of hydrocarbon oil enriched in C4 and C5 alkanes. According to the utilization method, reforming topped oil rich in in C4 and C5 alkanes is taken as a mainraw material, catalytic dehydrogenation technology, etherification technology, and aromatization technology are combined and adopted, etherified gasoline, aromatized oil, and propylene are produced, and by-product hydrogen gas is obtained at the same time; etherified gasoline and aromatized oil can be taken as high-octane rating gasoline additives to improve gasoline pool composition; the producedpropylene can be taken as a raw material of polypropylene devices, and hydrogen gas can be adopted in other hydrogen gas consumption devices in factories. The effective approach used for utilizationof reforming topped oil is provided, and the utilization rate and product added value of hydrocarbon oil such as reforming topped oil are increased. 本发明提供一种富含碳四碳五烷烃的烃油的利用方法，主要以重整拔头油为原料，充分利用其富含碳四碳五烷烃的特点，采用催化脱氢技术、醚化技术和芳构化技术的工艺组合，
