Process for producing hydrogen from ethanol, characterized in that it comprises the following steps: a) provide a reactor with a catalytic system comprising a nickel oxide, at a content between 10 and 60wt%, on a support, selected from the group of: alumina, calcium aluminate and magnesium aluminate or mixtures of these compounds in any proportions, and with a promoting element selected from the group comprising alkali metals or alkaline-earth metals, wherein said promoting element comprises potassium, present in the catalyst at a content between 0.5 and 5%wt; b) provide said reactor with an ethanol feed, with a space velocity (LHSV) between 0.5 and 3.0 h -1 and allow contact with the catalytic system; c) provide said reactor simultaneously with steps (a) and (b) with a hydrogen feed, to establish an H 2 /ethanol molar ratio between 0.2 and 0.6; d) provide said reactor simultaneously with steps (a), (b) and (c) with a steam feed, to establish a steam/ethanol molar ratio between 3.0 and 6.0; e) adjust the operating conditions of the reactor to a temperature between 350 and 550°C; f) allow the conversion of ethanol to a stream containing methane, CO, CO 2 and H 2, in the conditions established in the preceding steps; g) send the mixture of gases produced in step (f) to a unit operating under typical conditions of primary reforming of the industrial steam reforming process to permit the conversion of the methane to CO, CO 2 and H 2; h) treat the mixture of gases produced in step (g) by means of typical conditions of the "shift" step of the industrial steam reforming process, to permit the conversion of carbon monoxide to CO 2 and hydrogen; i) purify the hydrogen produced, derived from the shift reactor, by the methods used in the industrial steam reforming process. a) provide a reactor with a catalytic system comprising a nickel oxide, at a content between 10 and 60wt%, on a support, selected from the group of: alumina, calcium aluminate and magnesium aluminate or mixtures of these compounds in any proportions, and with a promoting element selected from the group comprising alkali metals or alkaline-earth metals, wherein said promoting element comprises potassium, present in the catalyst at a content between 0.5 and 5%wt; b) provide said reactor with an ethanol feed, with a space velocity (LHSV) between 0.5 and 3.0 h -1 and allow contact with the catalytic system; c) provide said reactor simultaneously with steps (a) and (b) with a hydrogen feed, to establish an H 2 /ethanol molar ratio between 0.2 and 0.6; d) provide said reactor simultaneously with steps (a), (b) and (c) with a steam feed, to establish a steam/ethanol molar ratio between 3.0 and 6.0; e) adjust the operating conditions of the reactor to a temperature between 350 and 550°C; f) allow the conversion of ethanol to a stream containing methane, CO, CO 2 and H 2, in the conditions established in the preceding steps; g) send the mixture of gases produced in step (f) to a unit operating under typical conditions of primary reforming of the industrial steam reforming process to permit the conversion of the methane to CO, CO 2 and H 2; h) treat the mixture of gases produced in step (g) by means of typical conditions of the "shift" step of the industrial steam reforming process, to permit the conversion of carbon monoxide to CO 2 and hydrogen; i) purify the hydrogen produced, derived from the shift reactor, by the methods used in the industrial steam reforming process.
