Process for converting a hydrocarbon feedstock into alcohol(s) wherein the hydrocarbons are first converted into syngas, which is converted into alcohols, by converting hydrocarbon feedstock in a steam reformer into stream A′of carbon oxide(s), hydrogen and water, feeding stream A′with hydrocarbon and oxygen feedstocks into an auto-thermal reformer to produce stream A, converting stream A in an oxygenate synthesis reactor into stream B containing methanol, ethanol, propanol(s), H2, C1-C3 alkanes, CO, CO2 and water, separating stream B, into stream C containing CO, C1-C3 alkanes, H2 and methanol, stream D containing CO2, recovering stream B containing the ethanol, propanol(s) and water, treating stream C to separate into a stream comprising CO and a stream comprising H2 and C1-C3 alkanes, reintroducing part of stream C with the stream comprising CO into the oxygenate synthesis reactor. At least part of stream D is reintroduced into the steam reformer. |
