Low pressure combined bed two stage catalytic reforming process

摘要

Under low pressure, the raw oil is contacted with platinum-rhenium catalyst in semi-regenerative reforming reaction stage formed from one fixed-bed reactor, then the obtained effluent after reaction is completely fed into the continuous regenerative reaction stage formed from 2-4 moving-bed reactors and one regenerator which are series-connected together, further is contacted with the platinum-rhenium catalyst, then the reaction product is undergone the processes of cooling and flash evaporation, and separation into hydrogen-enriched gas and reformate.
