Abstract This invention relates to a combined technology for cracking C5 fraction to produce methyl tert-amyl ether (TAME) by utilizing ethylene and use it for rich n-pentane-contained parafins of ethylene-cracked raw material. It features that decyclized pentadiene, selective hydrogenation, etherization reaction and saturated hydrogenation technique are organicly combined to decrease hydrogen consumption to the maximum extent, and an ideal harmonious ingredient without lead and containing oxygen and high octane number gasoline-TAME is obtained. Catalstic-distilled etherization reaction is used, tert-amy ethylene reaches deep transformation; the saturated-hydrogenated C5 paraffins contain rich n-pentane used as ethylene-cracked raw material or gasoline ingredient; crude cyclic tert-amyl diene can be produced in combination, and after further refining, it can be used as raw material for fine chemical industry.
