PROCESS AND PLANT FOR REFORMING HYDROCARBONACEOUS FEEDSTOCK

摘要

The present invention provides a process for the production of a synthesis gas mixture containing carbon oxides and hydrogen from a hydrocarbon feedstock material comprising: providing a reforming zone having a plurality of chambers charged with a catalyst effective for catalysis of at least one reforming reaction; supplying to the chambers of the reforming zone a vaporous mixture of the hydrocarbon feedstock and a reforming reagent; maintaining the reforming zone under suitable reforming conditions for reforming of the hydrocarbon feedstock and reforming reagent to form the synthesis gas mixture by supplying to the reforming zone a fuel for heating the chambers by combustion and by supplying to the steam reforming zone a vaporous stream comprising combustion oxygen in which the fuel may be combusted; humidifying the vaporous stream comprising combustion oxygen; exchanging heat between the humidified vaporous stream comprising combustion oxygen entering the reforming zone and the synthesis gas mixture exiting the reforming zone; recovering from the reforming zone a cooled synthesis gas mixture; and recovering from the reforming zone a vaporous combustion products mixture comprising the products of fuel combustion in the reforming zone and any uncombusted materials supplied to the reforming zone and to a plant constructed and arranged to operate such a process.
