Abstract:
Temperature-controlled CO shift technology can fundamentally overcome theover-temperature problem of the catalyst bed in the “double high”(high temperature &.high pressure)crude gas CO shift reaction,thanks to which it has been favored by many enterprises and sci- entific research units,witnessing a very strong development momentum in recent years among temperature control technologies.Several repre- sentative companies in China have developed their own temperature-controlled CO shift technologies,which feature respectively different struc- tures.The technical characteristics of each type of temperature-controlled CO shift reactor are introduced in detail and are compared,which is of guiding significance for the selection of temperature-controlled CO shift reaction technologies and reactors.
