The present disclosure relates to a catalyst composition comprising copper and iron on a support for use in a process for the synthesis of higher alcohols from a syngas feed stream comprising hydrogen and carbon monoxide, the catalyst composition being remarkable in that the support is one or more zeolite, in that the total content of iron and copper is ranging from 1 to 10 wt. % based on the total weight of the catalyst composition and as determined by inductively coupled plasma optical emission spectroscopy, in that the Cu/Fe bulk molar ratio is ranging from 1.1:1.0 to 5.0:1.0 as determined by XRF spectroscopy.

Copper-iron-based catalytic composition comprising zeolites, method for producing such catalytic composition and process using such catalytic composition for the conversion of syngas to higher alcohols

The present disclosure relates to a process for converting syngas to C2+ alcohols, said process comprising the steps of providing a reactor, of providing a catalyst composition and one or more acidic materials within said reactor, of providing a feed stream comprising a mixture of Hand CO; and of contacting said feed stream with said catalyst composition and said one or more acidic materials under reaction conditions to provide product stream. Said process is remarkable in that said catalyst composition comprises an active phase comprising CuFe deposited on a carbon-containing support, and the one or more acidic materials are one or more zeolites having a Si/Al molar ratio ranging between 2 and 200.
