Esters are hydro genated to provide product alcohols such as ethanol. In one aspect, the hydrogenation is conducted to substantially completely react the hydrogen and provide a hydrogenation product containing product alcohol and unreacted ester which is recycled. In another aspect, hydrogen for the hydrogenation is provided by pyrolysis of biomass and hydrogen separation operation, and the rate of hydrogen supply from the pyrolysis to the hydrogenation is controlled by adjusting the purity of hydrogen from the hydrogen separation operation.
