LIQUID HC PRODUCTION VIA CAT. REFORMING

摘要

Process for producing liquid hydrocarbons from a hydrocarbonaceous feed which comprises the following steps: (i) catalytically reforming at least part of the hydrocarbonaceous feed at elevated temperature and pressure with steam in at least one reforming zone; (ii) heating the reforming zone(s) by means of a carbon dioxide-containing heating gas comprising a product obtained by partial oxidation of reformer product obtained in step (i) or of a remaining part of the hydrocarbonaceous feed or of a mixture thereof with an oxygen-containing gas in an oxidation zone; (iii) separating carbon dioxide from heating gas obtained in step (ii); (iv) catalytically converting at least part of the reformer product obtained in step (i) and/or gas obtained after separating off carbon dioxide in step (iii) at elevated temperature and pressure into normally liquid hydrocarbons; and (v) combining at least part of the carbon dioxide obtained in step (iii) with hydrocarbonaceous feed for at least one of steps (i) and (ii).
