CA 2395768

Long chain alcohols and acids or other similar oxygenates such as esters are produced from paraffins (1) of similar carbon number by a process comprising paraffin dehydrogenation (2), carbonylation (9), and separation (21, 24, 30). Preferably a mixture of paraffins extending over several carbon numbers and recovered from a kerosene fraction is processed, and unconverted paraffins are recycled to a dehydrogenation zone. Alternative reaction zone configurations, catalyst systems and product recovery methods are disclosed.

On produit des alcools et des acides à chaîne longue ou d'autres composés oxygénés similaire, tels que des esters, à partir de paraffines (1) à indice de carbone similaire, par un procédé comportant la déshydrogénation des paraffines (2), la carbonylation (9) et la séparation (21, 24, 30). On traite de préférence un mélange de paraffines s'étendant sur plusieurs indices de carbone et récupérées dans une fraction kérosène, et on recycle les paraffines non converties dans une zone de déshydrogénation. D'autres configurations de zones de réaction, de systèmes catalyseurs et d'autres procédés de récupération de produit sont décrits.
